Not bad, but plenty to work on. I personally think the camera angle sucked, however there not much you can do in that car to "fix" it. Basically I had a hard time seeing the course until you were on top of it, and difficulty gauging how close you were to the cones, until I saw that you were way off (more on that later).

Good things: you look ahead, most of the time. You are finding the next element and figuring out where you need to go before you complete the current one. Its a little hard to see from the video if you are doing it all the time, but you seem to be doing it most of the time. Its something you'll have to constantly work on, but you seem to understand the basics.

"Bad" things:
-From the video, it sounded like you coasted a lot. Generally you want to be either gas, brake, or modulating the throttle (keeping you speed up/small acceleration in sections where you can't go flat out).

-It looked like you were several feet off of nearly every cone, especially in the turns that were over 90 degrees. If you are in a U-turn and you are 4 feet off that apex cone, you just went 8 feet out of your way (4 out and 4 back). Start aiming to hit cones until you actually do. It'll tell you where the body of the car ends and where you need to be. Then back off a bit so you stop hitting cones, but are still right on top of them. I'm assuming the camera was a gopro based on the fish eye distortion. Mount it on the rear quarter panel on one side of the car with the large suction cup so that you get a good view of how far off the cones you actually are.

-Your steering inputs are late, and you need to connect features together. Turning early means you turn less, which allows you to go faster and straightens out the arcs thus minimizing distance. For connecting features together, study the slaloms. I saw you go up to a cone, turn, go straight, go to the next cone, turn, etc. The whole thing should be constant back and forth fluid motion. The steering wheel shouldn't be static and there shouldn't be any straight parts. Once you've got it linked together, you should notice you can carry a lot more speed. Then you should start working on "backsiding" the cones in the slalom. Basically you want to be turning so far ahead that you are starting to turn for a cone when you are next to the cone before it. If you draw a line between two cones in a slalom, you want to cross that line right on the backside of the first cone and start turning right around when you do that.

Does your club allow you to ride in other people's cars? If so, I would recommend you take advantage of that. Ride in cars similar to yours (if possible) and pick out one major thing others are doing that you are not, such as slamming on the brakes. Then experiment with that thing on your runs for a few events.

Remember, its cones in a parking lot. Don't get too focused on what you suck at to the point where its not fun. Its supposed to be fun, and most of your improvement comes from experience, pushing the limits a little bit each day, not trying to make massive improvements in one go.

Awesome advice!

Thanks! This is exactly what I needed. Looking ahead is the one thing I've really been working on all season, and it has definitely helped. I'm normally closer to the cones, but we had 3 runs in either direction that day, and in both cases I coned my first two runs trying to get close to the cones, so my third run I backed off a bit to get a clean run in. It's definitely something I've been more conscious of lately - especially in 90 degree or more turns. I'll definitely try a different mounting position for the gopro next event.

I've been doing as many ride alongs as I can, and it's definitely helping. If you had to pick one specific thing to work on next, what would it be? I find I can learn better if I try and focus on improving one bit at a time.

And don't worry - I'm having way too much fun, I just like to improve! I wasn't sure what I should be working on next, as I wasnt able to get much advice at local events. I did... Maybe 2 events last year, + this season, so I'm still relatively new to this :)

Man you shift a lot. Next time do one of your runs without all the drops to 1st. I think you'd be surprised. In the 1st gear shift that goes from :37 - :50 you mat it for about 2.5s that entire time and hit some rev limiter in there. An upshift costs you about .2s. It's really surprising how often you should downshift even in a low power Miata. I'll admit though that the camera angle does make it fairly hard to see how tight the turns are.

Speaking of getting close to cones. I got a good pic from one of the photographers at the last event. Only hit one cone that day and it wasn't that one. Was driving a buddies 155whp SSM car, man that was fun.

I agree, only focus on improving one thing at a time, because what ends up happening is your normal skills suck a bit as you concentrate on the new thing, which ends up splitting you concentration as you try to keep you skills at their normal level while working on the new thing.

I'd say steering is probably most important for you right now. Once you start getting it "right", it will unlock greater speed potential. Even though it sounds backwards, I've found that you generally need a minimum speed to drive a slalom correctly, and the faster you go, the easier it becomes. The back and forth weight shifts from faster speeds actually help turn the car (not drifting though)

Will do! One of the things I've been told before is to try to be more smooth with my steering inputs - is that kind of what you mean? I'm trying to wrap my head around what to be thinking about during a run. For example, I've been telling myself to look up for most of the season, and I put a piece of tape across my windshield and tryed not to look below it. Maybe if I focus on linking my turns?

I'm not surprised I got comments on gears. That course really put me in between first and second in a number of places. So I'll shift out of reflex when really it's a toss up whether it's worthwhile or not. But in general, I agree with you. Usually I have my gears figured out early in the day. But as conditions constantly got better, (started full wet and then the sun popped out during lunch) the speeds changed in such a large way that my gear choices in the morning were way off after lunch. Which threw me out a bit. I appreciate the feedback though.

Linking turns, which is part of being smooth, involves looking ahead. Not only are you looking at where you are, and where you need to be, but also where you need to be after that, and trying to form one smooth arc that links all three. This is different than "point to point" driving where you get to where you need to be next, then you decide how to continue. There is a slalom in your video at about 30 seconds. To enter, you jerked the steering wheel left. Visually what I saw was you exited that turn, then decided you needed to be over to the left to enter the slalom. Since you were already on the slalom when you decided that, you had to make a big steering input that didn't flow well from what you did before.

I have a '95. Great handling car (although mine is set up for STU and has a lot of suspension bits).

I'm running 17x8.5 Kosei's, and 255/40x17's. Be aware, that even with 3 degrees of camber, and rolled fenders, the 255's have some very tight fitment/rubbing issues, so unless you run a class where you can actually pull the fenders, those are going to be your max size rubber.

I only planned on running 235s or 245s at most. The local competition isn't really very good class wise, with 20 to 30 cars per event. I'll be running SM but the work I'm planning to do would be less than even STU limits me too. Aside from replacing most of the bushings and cooling system, I'll probably only add a SSK, camber plates and some sort of mild suspension (GC coil over with koni yellows and 450/550 springs was recommended as a good starting point).

Out of curiosity what have you done to your M3?

One comment though - I learned on this car that I'll never again buy a single adjustable shock. DA's are the most amazing thing ever made, allowing you to make major adjustments to how your car handles with nothing but a screwdriver (for rebound), and the little Koni tool (for compression). Spend the extra money for properly valved DA's and once you figure out how to adjust them (I'll post a short cheat guide for that tonight too), you'll never regret spending the extra money, guaranteed.

Today was very cold although that might have helped even the playing field a bit with my lovely stock tires. Muffinpox helped me not drive horribly (and drove my car a bit) and I ended up coming second in novice class, and more importantly, I won a t-shirt. I had a dirty time 2 seconds quicker than my fastest with only one cone, but it wasn't meant to be.

Why recommend HP+? For street and autocross, they are generally dusty, noisy, and overly aggressive (pads and rotors will wear out much faster). With those two things being the focus, and track days being rare, I'd go with the HPS instead.

I think I could get away with HPS all the way around but i'm in a miata. Right now I have HP+ front and HPS rear. They have lasted me about 4-5 months, 1 and a half track days, and maybe 6 autocrosses and the HP+s are very close to gone (not a fair comparison because they are on the back, but the HPS have tons of life left). My brother and another friend got Carbotech XP8s and XP10s at the same time as I got my hawks, they ran all the same events and they have tons more life left in their pads. When I do it again Im probably just running cheap pads for daily/autocross and switching to Carbotechs for the track. Also the HP+s dust quite badly, I have to clean my nice wheels at least once a week. Not to mention the noise. My friends will be waiting for me outside their houses because they hear my brakes from more than a block away. In any case, on RS3s I never got them to fade on the track. Though im new to it so I could maybe do that when I get better at breaking harder.

EDIT: I seem to remember that reading that the HPS actually bite a bit better at first. Been awhile since I read that article everyone loves linking for the differences between HPS and HP+s.

Might I sway you into running a more aggressive pad in the rear, at least if you're on street tires and assuming you want an autox setup.

It helps subside the low-speed lock-up that is easy to experience on an autox course. I went from HPS all around to HPS front/HP+ rear and it's helped tremendously. Not that we should be braking all too much anyways, lol.

The dust and noise does suck, but I've ran HP+ in all my miatas for the past 5 years so I guess I'm use to it.

Im running RS-3s, so yeah, street tires. Im pretty used to the noise by now too but it still is embarrassing to me when Im picking someone up or going out. Anyway Im leaning more towards tracking my car. I'll probably go balanced before I try to rear bias, just because I dont want to start spinning all the time.

I've found EBC to have pretty fantastic dual purpose pads. The yellows are good enough for light track duty, and you can step up to blue when you out grow yellow. I've used both on the street without any issues whatsoever besides dust, which I think are still less than HP+.

EBC yellow/blue are what HPS/HP+ should be.

The HP+ are plenty bitey but I don't recall them being all that noisy except when cold. I never had a problem with them on the street, but I was doing a lot of autocrossing and tracking at the time so a compromise here and there never bothered me.

I love the way they bit and were basically impossible to overwork in a light/low-power application.

Allow me to post a quote from Bob Tunnell (multi time national champion in BMW E36's, and owns a BMW shop in Colorado - BimmerHaus. He and his wife have combined for something stupid like 30+ national championships):

"If you need to trim the budget a bit, I consider the double-adjustable rear shocks to be the single most important component - they are essential for good handling on an M3. If you decide you absolutely *can't* afford them, try to at least get the externally single-adjustable rears at <price>..."

Bob knows more about setting up E36 M3's than I'll ever even pretend to know, and the above is his advice on the most important piece of suspension tuning on an E36 M3.

Autocross video time! My third event and the first time i managed to make gopro work and would like some criticism (positive and negative) on how i can get better at this whole malarkey. Driving technique, car upgrades, camera angles, everything is fair game. I tried to make this not a boring "hood cam" video, becuase nobody but the driver likes those.

First run is a track learning slow run, I didnt tighten the mount in the second video so it wobbles a bit, stick it out the third run looks objectively cool :) Personal FTD is second run before the rain started.

Sorry to poo poo on your parade, but that video is not very good from a coaching standpoint. I can't see your hands, I can't see your helmet (thus where you are looking), and two of the views don't give me any sense of the course.

First view: you were probably 2-3 feet off of every cone you should have been only a few inches off of on the left side, which is the easy side to get correct.

Second view: I can kinda see the course, but the massively uneven angle makes it hard to comprehend without really concentrating. I would probably watch the section 50 times and really comment, but I'm not gonna go through that effort. Only thing I got from this was you were feet off of important cones on the right side as well

Third view: bloody hell, this is terrible. Interesting and artsy, but utterly terrible for coaching. Also, the camera was mounted too low. If you were on the cones like you should be, then your camera would have been knocking them over.

I probably could comment more, but I'm not putting in the effort unless you make it easy for me.

Err, sorry i guess? I didnt really make the video for coaching. Autocross videos bore people to death because "Trunk mount facing forward" or "windshield mount facing forward" are dull as hell to watch, i shot it for the "interesting to friends and family" value rather than just technique. Excuses: Maybe a Lower than usual mount and massively wide angle might made the cone gap look worse than it is, i was pretty drat happy with my times compared to the rest of the field.

:smith: I was really proud of that third shot. Dont worry, I actually took a spare cone and set it below the camera, even leaving a little space for the roll of the car.

I can certainly take "get closer to the cones" as advice, thanks.

Last autox for the season was this Saturday and bsamu was there! I got to drive his BRZ and let him drive the S2000 so I could get some onboard of him driving to show him where to correct how he was driving, but my mount fell off. I would suggest everyone go to an autox school when starting off like he did, he was pretty drat quick and the only thing I really needed to yell at him about was not keeping his eyes up and staying tighter on the cones.

There was a literal herd of S2000s there, I beat them all heh :smug: I also let one of the instructors drive my car who usually will post FTD in an NC miata on street tires since the driving line is pretty similar. Sorry for the whiteout, it was super glarey for some reason and my fastest run is just all white.

His run:

Being in the car with someone else driving and having videos is definitely the way to go for seeing where you need improvement, I managed a 73.5 clean for my fastest run and I think his second run was a 73.08 with two cones but there was a section there where in the video you can see he was entering the complex at 41s 14mph faster than me and keeping the speed up into the next braking zone just because he had a better entrance line, got tighter, and was smoother on throttle/steering modulation so he could go into the zone without braking like I did.


Now crossposting from the BRZ thread:

Bsamu graciously let me drive his BRZ at autocross this Sunday so I thought I'd post some impressions, keep in mind coming from a S2000 using star specs.

I liked the car, the suspension and chassis are well set up and easy to hop in and drive hard. It has everything a car needs to be fun to use on the street; it is pretty predictable and doesnt bite if pushed too hard, it maintains composure even when the tire grip limit is exceeded and it will come back from skidding quickly and controllably. It does understeer toward the limit a bit but it can be balanced with throttle rather easily. I was trying to keep wheelspin down since it was cold, but in the harder right handers it could be coaxed into it although with stickier tires it feels like that tendency might go away. The steering is fast and pretty sharp but isnt as telepathic as the S2000s. Also the car is very easy to place on he longer corners and is narrow which are a boon to placing close to cones. I could tell within a few seconds it was about as wide as the S2000 but the cabin feels way more spacious inside. Visibility is good out of the cabin, the driving position seems pretty upright although that might have been bsamus seating position. I can see the S2000s redline/speedo in my peripheral while driving so I have a general idea of where I am in the powerband but in the brz I had to look down which threw me off a bit during the run when I hit the second gear limiter in two separate sections.

Now for the bad:
1) The engine power is underwhelming. I know it's only 150lbft and 200hp but even coming from the S2000s 240hp/141lbft it felt like it was underpowered. I guess I was expecting it to be a bit more frantic towards redline but it is pretty much just a flat torque curve from 2-7.4k. I like the linearity which makes the car super easy to push and it was deceptively quick as well, peak speed in the S2000 was around 60 whereas the BRZ hit its limiter in second which is like 57-58? The power works with the package though.
2) The primacys are awful. They make a good amount of grip, my run was a 77.4 and I think the car was capable of a 74-75.xx run. Compared to the S2000s 73.5 fastest and probably 70-71 with a perfect run. The difference wasn't in grip but the response. They are soft tires and don't communicate particularly well. In longer corners where you could be super smooth they were fine, on quicker transitions they noticeably would take a few tenths of a second to finish rolling over and start turning the car. They weren't all bad for the street, they were predictable and didn't say "gently caress off" when asked to quickly transition the car, they just were mushy. There were a few sections I could have hit way faster but didnt have the confidence in the tires to get the car turned in where I wanted it in the time I needed it. The car is super easy to hoon around on the tires though, despite their lack of reflexes.


Overall, awesome little car. I'd compare it more with a four seat miata than a four seat S2000 though.

Muffinpox tried to take some footage of me driving but I went off course and he decided my dashboard should be the focus of his movie.

My camera hated you I think. I can't believe my mount fell off at the staging line when you were driving my car.

Err, sorry i guess? I didnt really make the video for coaching. Autocross videos bore people to death because "Trunk mount facing forward" or "windshield mount facing forward" are dull as hell to watch, i shot it for the "interesting to friends and family" value rather than just technique. Excuses: Maybe a Lower than usual mount and massively wide angle might made the cone gap look worse than it is, i was pretty drat happy with my times compared to the rest of the field.

A good shot is a camera mounted on the farthest right part of the trunk lid and then elevated like 3 feet so it looks downward towards the hood. You can see cones and it's visually interesting for people to watch. Also get closer to the cones.

One feature I haven't used yet in the BRZ is the configurable shift light and buzzer. At my next autocross I'll set it up to start whining at 7200 rpm or something to give me a bit more of heads up before brutal fuel cut.

I'm good at this trick too. Sideways into the stop box with the wipers on? Yeah... :3:

It's more fun in an NA Miata when you hit the high flashers and the headlights pop up.

I got killed in the rain on the weekend. I can't seem to control the rear-end when coming out of the corner.

Given you didn't set out the video for coaching and driving technique critique, I enjoyed the third shot, especially the water spray. I thought it would work well for a more sophisticated video - those you posted had a definite "experimenting with camera work" feel to them - as a short segment, running for maybe a second or two, in a video otherwise mainly composed of a high-and-behind shot as was suggested by Muffinpox. That requires multiple cameras, of course, as well as figuring out where to mount the camera for a shot like that such that you can still place the front wheel right on cones without the camera knocking them over - the concern isn't for the safety of the camera, it's for your driving line!

I also like videos that include at least some direct views of the driver - like mounted on the passenger window or the far corner of the windscreen on the inside, pointing at the driver so both hands and the face are always visible - steering wheel, into the open-face helmet, gear shift (and windshield wiper and signal light control stalks, too, for the fun little mistakes).

S2000 fun.

Your car seems quite a bit oversteer-y. Isn't it destracting? There were moments where the slide was definitely not helping either of you.
