Autoclub speedway in car, 9/8/13
 

my in car vid from my best lap of the day, not happy with the pace, its been over 2 years since ive been there, so i have alot of rust to knock off. Plus some setup changes would help too. enjoy

personal best lap of the day



Last session of the day, several laps

^ Did I see your speedometer correctly? Did you pull 130 mph through T1 & T2? Damn, I thought I was doing good maintaining 100-110 mph through the same section.

that's actually 140 on the speedo ;) but from reviewing my data i think our speedos get a little inaccurate that high, my GPS logger had me at like 135ish

Nice, either way its quick!

my oval entry was a bit shallow since i hadnt been there in so long, reducing my overall speed, ill work on that next time

added a second video from my last session

Did this track for the first time this weekend, lot of fun. Missed you by a week Clint and I had martin instructing me. He taught me the same lines, but he did teach me to ride a bit higher through turn 1(maybe because stock suspension?).

I was playing w 2 vs 3rd gear on turn 3, I like the idea of using it at the hairpin as well if necessary like you did a few times.

Why do you prefer to stay low on main straight and T1/2?

My best time was a 2:11 which I don't think is too shabby for a newbie that is mainly stock and the first time I did the track. I think I can probably get down around 2:05 but then I think suspension/brakes would limit me. I definitely learned the extent of my suspension on this track. The sweeper/U-turn is definitely a place I could pick up some speed, and I was staying below 130 per martin's advice on turn 1/2 but I could definitely have gone faster.

yeah if your car has less over all grip (from either lack of suspension mods and/or tire grip) then a higher turn 1 entry is better/safer, since it widens the turn out and you use the down hill of the oval to your advantage. the disadvantage is you have a longer distance to travel. so its all strategy figuring out how low in the oval you can go without causing you to scrub speed and/or lose traction.

i used 3rd in turn 3-4, 2nd in the hair pin. 3rd had enough power band to pull me out of 4 fine.

i stay low on the oval straight cause its a shorter distance to travel. i was on the lower side of turn 1-2 oval because honestly, i hadnt been on ACS for 2.5 years, never been there with the Z ever, i was playing it safe and didnt wanna be that close to the wall lol.

for ACS specifically, i need a more aggresive front pad, i was losing alot of time in the brake zones

Thanks man, good info. I did hit second a few times on T3, but later in the day decided to stay in 3rd. I am still 50/50 on it but the problem is really suspension. I body roll like a MoFo in turn 3 to make that little tuck move to line up 4. I hit the 4 exit correctly only once and understand it, but most of the time I just got too wiggly in T3 to really exit correctly. Only other option is to scrub more speed and hit 2nd gear to exit.

T1 T2 I never felt unsafe or uncomfortable on, the highest speed I remember seeing was ~130 and I went to 3/4 throttle just to be safe.

Tires were not the problem, brakes and suspension I definitely felt the limitations-much more than any other track I have been on. ACS will definitely check your hardware and lives up to its name as a professional racetrack.

That being said I don't think I have ever had more fun in my life lol. Hope to see you out at a track day soon.
