The Official 370Z Autocross Thread

IMWEZL · 07-13-2009, 12:01 PM

I just recently had my first Autocross event with my 370Z. Big difference going from an SM Dodge Neon SRT4 running Hoosiers to a stock 370Z. My times sucked, however that was a driver issues.

I asked a fellow 370Z owner (didn't race/purchased the night prior) who gets FTD more often than not to drive my car. He knocked 3 seconds off my best official run on the first lap. His vids are on my youtube too.

My overall experience was that I could be more aggressive with the car. I did understeer a few times and drifted around a few turns. My best times came with the VDC on. My weakness was the slalom. I never had a good feel as to how big the car was as I entered and exited the slalom.

Here's one of the vids. Not sure why the quality looks crappy I recorded on 1080 HD.

Has anyone else noticed that with the synch-rev on the car momentarily continues to apply the throttle even after you let off and hit the brakes?

I ended up just turning it off, it's not like I'm downshifting anyways on the course. With the system turned off the car behaved as expected or until I got to happy with the throttle and steering.

Had an awesome auto-x this past Saturday. This particular club is one that runs a long course, a little over 100 seconds this week (actually short for them). This is also an anything goes club as far as mods go. There are 2 classes, cars with tires of 140 treadwear rating or above, and everything else.

There were 4 Corvette Z06's, a Viper, a supercharged Exige, supercharged Miata, twin turbo Miata, turboed MR2, and a bunch of other machinery there.

I pulled off a win in the "street tire" class with a 1.5 second gap to 2nd. Got 5th overall (0.2 seconds away from 3rd).

For this event I ran camber control arms and dialed in -2.6 degrees in front and -1.6 in the rear, as well as the Hotchkis sway bars. The car was very responsive and handling was excellent!

I haven't searched yet but I have been wondering how much the car would benefit with more negative camber. Is that the max you could get out of it? Just wondering what made you choose that particular setting.

Nice result. Were you running the stock B'stones?
