First test day today, and it turns out the tires on my 330i didn't take long to eat it. Near the end of the day after about 10 runs total, I noticed the front passenger sidewall was cracked and bulging. Not sure if that happened today, but I throught I gave it a pretty good look while I was setting the pressure in the morning. Going to do a really early morning bleed of my e36 328is brakes in the morning for the competitive event.

It'll be nice to get a direct comparison between the two cars on what should be a very similar course due to the setup constraints. I already prefer everything on the e36 except for the steering ratio/transmission so it should be interesting.

I'm not too crazy about the tires my car's PO put on either. Goodyear RSA's or something.

The DC region SCCA seems to do autocross instruction days once a month or so. I might try to do one of these so that I can get some basic idea of what the hell I'm doing. My only experience with anything like this before was one of the Mazda Rev it Up events after I got my mazda 6.

If you're not familiar at all, the instruction day is probably the best way to start. I did my first one last year at a regional event so it was a little overwhelming. It didn't help that they made me the first car of the day. The school today was much better - I got seat time with a good instructor who eased me into going quick. Plus I got way more runs that I could get on a competition day.



I didn't get any pictures of it, but in typical BMW fashion a z3 popped a coolant hose mid-run.

Three things I learned today:

  • Yokohama Neova Advans are way better than the decade-old Bridgestones that I ripped to shreds last year.
  • Better tires still aren't much help when your front wheels have positive camber because of stock alignment.
  • Even though I feel like a driving god because I snagged a better raw time than a 350Z, an '05 STI, a couple of Miatas, and an Elise (!), there will always be some rear end in a top hat in a '94 Protegé that will humble me with a 3-second faster run.
:gbsmith:

If it makes you feel better, the FTD for the autoX I did today was set by a 97' neon. I was almost 5 seconds off in my 328, but I blame the 2 year old all season tires for some of that. Felt pretty good to beat an early model e36 with Rcomps and get a half second within an 06' M3. Despite the slower rack, smaller engine and worse tires I felt way more confident in my e36 compared to my e46. Mechanical throttle with linear resistance really helps control a tail happy car in a bumpy parking lot with off-camber corners and wierd asphalt joints.

Hopefully my friend will upload his pictures soon. He got a great shot of some old man with a corvette annihililating the cone with the timing system reflector.

That stopbox looks terrible, and dangerous. If you brakes failed before the turn, you'd have about 30 feet until you hit what look to be spectators. We just had a huge thing in our region about making stops that are straight because when you have a sharp turn before the stop, people were going at, and often above their limits to get that last hundredth of a second off of their time and ended up punting two of our timing lights a good 40 feet.

That actually happened to us on Sunday. They put a really tight corner before the stop box (or slow box, it wasn't even possible to come to a stop) and everyone was having trouble with it. FWD cars were understeering towards the timing cone and RWD cars were hanging their rear end out at it. In the end an old man with a Corvette who was getting loose all day hit the throttle mid-exit and spun out into the reflector. Luckily they keep spares and a lot of tape.

The parking lot that that club runs in is tiny, oddly shaped and filled with poles, so they have to make convoluted and sometimes slightly dangerous courses just to keep the run times over 30 seconds.

Ours is also limited by the length of the cord for the timing equipment, and none of the parking lots they can get access to are good.

These tires are great, I have maybe 3-400 miles on them so I can't tell if dropping the pressures or the autocross wear was making them better but they seemed to be making more grip all day. My fastest run was 4 seconds off the lead car.

Also beat an '09 GTR.

Nice catch. Few weeks ago an old civic hatchback lose the rear before a sweeper, he caught the drift and held it perfectly through 2 gates. I was working the corner so I just watched him slide around me, it was awesome.

I order my tires from Tire Rack and have them shipped to the Montana Shipping Outlet warehouse to hold them until I can boogie down to the border and bring them across. It's not that bad of a drive from Southern Alberta and it saves a lot of money even after the gas & time (especially considering UPS charges bullshit brokerage fees). While I'm there I also get to read Ronald Reagan quotes and check out posters about how great Montana is.

Not sure if there's a similar service along your border but I wouldn't be surprised.

Even if you aren't near the border, tirerack is almost always cheaper with shipping + duty, which they tell you up front. My star specs were ~1350 from tirerack as opposed to 1450 from tiretrends or 1500 from 1010tires.


I actually just put ventus V12s on my e36, I have one trackday on them and a bit of highway miles. They seem like decent jack of all trades tires. Highway noise is minimal and ride seems good. Track day was hard to judge as they literally had 50km on them when I got there. They didn't seem to mind being pushed but I wouldn't say they are spectacular.

Things I learned today:

1) A brabus smart car with Rcomps should not be allowed anywhere near autoX. Dude nearly rolled it on the long sweeper where I was working. At least 6" off the ground on the inside.

2) It is possible for someone to enter the stop box completely backwards, not destroy the timing equipment or hit any cones inside the box.


Also got my first autoX experience with the Ventus V12s today. Overall I found them kind of numb - hard to tell when I was pushing too hard. I did play with the pressures a bit, and found that the fronts needed to be ~2psi lower than the rears to get rid of understeer. That will probably be my last time with the E36, I get star specs for my e46 this week.

I don't like it when stop boxes are after a fast section. Yesterday it was after a quick slalom and a lot of people came dangerously close to destroying the timing equipment.

This is an excellent idea, definitely going to do that next event. How do I gauge how far up to put the tape? The other thing I found really helpful was focusing on it during ride alongs - it's easier to think about when I'm not doing anything else, and helped me realize just how much I can improve in that regard.

I try to consciously look ahead during my runs, even if it might be affecting my times. Definitely noticing a change after a few events - I found myself anticipating sections of the course where I needed to prepare for a gate or two ahead. First few times out I was braking superlate for everything. Still weak on hairpins and slaloms where the cones start getting closer together near the end.

Since there's no honda specific thread, I figured I'd ask here (and get the answers I care about): How do people like their S2000s?

I went to an autocross school this past weekend (my first autocross event) and had a blast, and now I'm looking to get into it a bit more. The first thing I need to do is get a helmet, as I was borrowing someone else's helmet. I have a few motorcycle helmets but they both use the ECE 22.5 standard, whereas everything automotive requires SNELL. I'm leaning towards getting a specific SA2010 helmet as I believe that a M2010 helmet would only be allowed for autocross, not track days. I don't want to have to spend more money later when I could just get a dedicated car helmet now, but I have a few questions:

Where's the best place to buy an SA2010 helmet? None of the motorcycle sites I know sell them. Is there a reason to go full face over 3/4? I know the full face would be safer and the 3/4 would be a bit breezier.

http://www.helmetcity.com/page/HC/PROD/autosnellsa2010/bell-sport Is this what I should expect to pay for a reasonable full face SA2010 helmet, or are there some cheaper brands that are still acceptable?

Around here Snell M is fine for trackdays as long as it isn't a roofless or caged car. Check with whoever you want to run trackdays with.

Full-face always seemed pointless in a car to me, but I ended up with one anyway because of a complete lack of M rated openface locally.

A working rear swaybar makes a HUGE difference. The car actually goes where I point it now.

Also, is there anything funnier then someone new showing up in a "powerful" car (in this case a genesis 3.8), talking poo poo about how he's going to beat everything, and then posting the worst time of the day? I've never seen someone who has so little throttle control, it was just a toggle switch to him. He'd brake, coast through the corner and then when he got the car perfectly straight just mash the throttle. It was extra funny since he had a super loud exhaust that you could hear across both lots.

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).

Is there a ever a compelling argument to NOT use PAX for timing? Our region has a comically low amount of cars (30 is a GOOD event) so the SCCA classing pretty much means you run against yourself unless you bump up classes.

Our new timing system now does PAX automatically but they still seem hesitant to adopt it, ever for a seperate PAX championship in addition to the class specific and overall points champions. I guess it bugs me more because nobody in the region runs STU or BSP, so next year I'll be running SM against much better cars and drivers. But I'd rather be in the bottom of a full class then get 13 points for being able to park my car in a stopbox.

Thoughts, coming from an autoX newbie (only 1 year): Getting rid of rcomps in stock class is a good thing. It means if someone shows up in a newish car on good summer tires they have a place to go and not feel completely outclassed. This year I met quite a few people who decided not to come back because they have no one to compete against. Of course driver skill plays a huge factor for newbies, but if you have an experienced driver show them how fast their car can really be it helps keep interest up.

Also, this was kinda glossed over:

quote:

The proposal includes changes to the allowances for tires, shocks, sway bars and wheels as well as new language to allow for camber adjustment and the disabling of traction and stability control.

I know this is huge for BMWs, and possibly other manufacturers. I don't think there is any M or non-M car that can be competitive in slalom without camber changes. But being able to dial in lots of negative front camber can make BMWs quite competitive - If I recall correctly an e36 M3 took STU last year.

Kinda makes me wish I hadn't already bought decent coilovers already. I decided to go for STU/BSP instead of stock because of the rcomps and inability to get good camber. But with camber plates, konis and a massive front swaybar I'd probably have just as much fun for 1/2 the price.
