I ran a more or less brand new (less than 500 street miles) set last Saturday at Streets of Willow. I did about 30 laps, weather was 100+ degrees. I could get another 5 days out of them, easily.

Admirable Gusto posted:Oh do tell please; I promise to keep the traction control on Ok, keep in mind: 1) I've never driven Laguna in real life, this is all just from my own racing experience and watching lots of races and other series at Laguna. 2) This stuff might not be applicable/work with your tires/skill/willingness to die. 1) Turn 2: You look like you're a bit shallow for the exit of the corner. You have a nice long straight after so you want to have a later apex and be on the power out of that corner as soon as possible. You'll want to start getting into the throttle by middle of the rumble strip and getting to WOT as fast as possible. Faster than that: The braking zone for 2 extends into probably at or a bit past the midpoint of the first rumble strip. You can get a bulk of the braking done in the straight and trail brake through the first rumble strip. 2) Turn 6: Again it's one of those nice long straight aferwards you want to maximize your speed down. It sounds like you're waiting a while to get back on throttle after the corner. I would suggest losing a bit of entry speed and turn in a bit later to try to get into full throttle by middle of rumble strip. Also don't spin and die. 3) Turn 11: Same as turn 6, sacrifice some cornering speed. Apex a bit later and go for early throttle, about midway through the rumblestrip. Also don't spin the car or you're hitting a concrete wall. And will die. Muffinpox fucked around with this message at 05:55 on Jul 12, 2012 |

The V12 is not something I would recommend for track use. Especially if you don't have the alignment dialed in for track use and especially if the tires are on the narrow side. Get the alignment right and go a little wider and they'll work better and last longer. Of course, that's true for any tire. One of those cheap little IR temp gauges goes a lot way toward getting the most out of your tires and helping set up the car. Everyone who does track days should be monitoring the tire temperatures and pressures to set up the suspension and get a feel for how the tires respond to pressure differences.

Admirable Gusto posted:I wonder if anyone who's familiar with Laguna Seca would please critique my lap: I've run Laguna 3 times and am really not more than a novice but I did see one thing that made me cringe. On one lap while passing another car you apexed 4 very early. Your speed was low enough that you didn't need all the track so everything was fine. One of my coworkers put his GTS in the wall on the inside of 4 because he went in hot, early and the instead of just letting go 4 off, he tried to save it. Thankfully both him and the instructor are okay. He was also luckily insured for it, so he was off buying a new car in no time. I guess I just cringe whenever I see people take 4 really early. What Muffinpox said about 11 is true. The game is late apex and get on the power as soon and as hard as you dare. This is the game the M3 played and lost. It's a well used section of wall. The game at 6 is similar but it's a normal apex. However, given the safety improvements at that corner you will no longer be collected by a wall. More likely stuck in the gravel, worst case upside down.

Yeah, accusumps are great. It's just a pressurized can of oil that sits just after the pump outlet (usually via a sandwich adapter at the filter). If the pickup starves there is a pressurized source of oil ready to go. We were possibly the fastest wet sump Subaru and never had an oil starvation issue with one of those hooked up. Some interesting stuff here: http://www.lnengineering.com/deepsump.html http://www.lnengineering.com/accusump.html I like the secondary scanvenge pump for the heads. That would be a good idea on Subarus... Hankook RS3 is probably the best value for a street/track tire, and has more grip than anything else in the category. They made that tire pretty much specifically for street tire class time attack. jamal fucked around with this message at 22:12 on Jul 12, 2012 |

Admirable Gusto posted:Or perhaps it's time to say gently caress it and get a dedicated track car I'd do this. Hell, part of the reason I've never gone much for a track day is because I've never had anything that I could track without worrying about the cost to repair / replace, and without ruining it for daily use (before I sold it the Miata definitely was cheap enough to track, but I'd need to put a rollbar in it - and any bar tall enough to pass for me would mean no top of any sort would ever work). Maybe in a few years when the MS3 has 200k miles and I've bought my wife something newer...

According to some of the Miata turbo guys, the R-S3s give the Nitto NT-01 a run for their money. I'm in the start/middle (what started it was snapping 2 timing belts) of making the Miata a dedicated, street legal track car. I need to be able to get to work in the morning.

I just want to say that driving fast and well and on track is hard as gently caress - not just technically, but physically.

I just got back from a long track event at Summit Point Raceway in west va and I was physically exhausted at the end of it. I now know why F1 drivers spend so much time at the gym. Was it a one or two day event? Two day events loving kill me if its hot. Drink plenty of water. Just constantly guzzle water and hit the bathroom before every session. Don't drink coffee or soda. One of the greatest things I got was a pop-up canopy. As always, know your physical limits. Most of the incidents I see during DE events are at the end of the day. There is nothing wrong with calling it a day early. Question for the rest of you. Do you ever practice getting out of your car quickly? Start fully strapped in with helmet on and so forth. Everything on like you would be driving the car. Random timer to give the green and you get the gently caress out of the car. Kill the motor, hit the extinguisher, undo harness, pull down window net, dive out window, and run around like a mad man (don't do this last part). It is something that you can practice in your garage and definitely something you don't want to learn in an emergency. It is kinda fun trying to beat your last time. I started doing it blindfolded. Practiced getting out the passenger window.

It was a 2 day event, 4 30-minute sessions per day. What I ended up realizing was by the time I did a lap and got to the start of the straightaway I was tensed up from head to toe and I tried to relax there. And yeah, water owns.

Do deadlifts, you brace a lot with your back and stronger muscles will make it less taxing. I started karting last year and races were 10 min with a 10 min break between heats. I would be exhausted by the 3rd heat and need to back off in the 4th when I first started. I had been running/cardio for a while at that point but doing back workouts had the most noticeable improvement on the ability to cope with the demands of driving, to the point where at the end of the season I did a 60minute continuous driving session at a flat out pace and felt like I could have stayed out for longer.

Bought some DTC-60s and did a 2-day; it was kind of boring because I drove in a 14 hour Chump the weekend before on the same course. Braking in a super front heavy FWD car is inducing. I had the option of going into the 3rd level run group, but I figured the speed differential would been too great; only could brush 100mph without the instructor in the car.

Admirable Gusto posted:Or perhaps it's time to say gently caress it and get a dedicated track car This is my plan, and I don't want to accumulate a bunch of parts I won't use on my current car. Sounds like V12s won't disintegrate on me, so I should be good. I've found that as I get faster it's easier physically because I'm fighting the car less and using less force. But yeah, still pretty demanding. Just a few free weight exercises for triceps, biceps, and back daily goes a long way. Seating position is critical too. If you have a heavy car, get closer to the steering wheel. If you've ever wondered why NASCAR drivers almost have the wheel under their chin, it's because they need more leverage to muscle the car around.

Buy a baffled oil pan, it's a lot cheaper than paying for a rebuilt Porsche engine. If you're serious about doing more than a few track days or even just want to get the most out of what you have, do it right. I had to get a baffled oil pan and a fuel surge tank to tackle the oil and fuel starvation problems inherent with the Elise. Seems odd given the nature of the car but it's the cost of doing business sometimes. I would also look into an intermediate shaft upgrade like the one here: http://www.lnengineering.com/ims.html. Again, $600 plus installation is a lot cheaper than 15-20k for a remanufactured engine. Edit: I'm really banking on the new 9A1 DFI engine in the Boxster not having these issues. They moved away from the IMS bearing design and added an integrated dry sump so here's hoping... quote:Or perhaps it's time to say gently caress it and get a dedicated track car There's a huge gap between tracking a car with some light mods and a full on track car. You can have plenty of fun with the car as it sits. That said, if I had to do it all over again I'd find 3 or 4 other people to run Spec Miatas with.

I've started finding my Sparcos quite uncomfortable after about an hour in the car, the left foot isn't wide enough, I think. No, future cats sole at their widest point are a little smaller than the width of you foot. I actually think theyre a bit too narrow, I heel toe with the side of my foot and can't reliably heel-toe in my S2000 with them unless I really turn my foot. They also have a very pronounced heel which is a bit uncomfortable after a long period of driving. If you can find them, I thought the drift cat width was just about perfect, the sole is as wide as your foot which makes them feel very natural.

That's not enough time to get remotely comfortable with the car to even enjoy the drive. On a racetrack, almost any car is a really good time, so put that $100 towards a track day with your car or renting a Miata (~$500) and get like 50+ laps.
