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.

i miss autoxing at the stadium. i used to run my spec v there.

Hahaha I figured the spam or whatever was going to get deleted.

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.

I never noticed. Good idea about turning it off.

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.

The car would benefit greatly from some more negative camber in the front. Unfortunately because of the way the suspension is designed, front camber is non-adjustable. The only way to change it is to get some adjustable arms like chris has

I wanted something aggressive, but still streetable. Normally -1.5 degrees is considered the max for street, but I set the front toe to 0.0 and set some more camber. These camber arms are set up to be almost all negative, as my mechanic said when we were installing them, "There's an oh my god amount more left there". I think I could hit 5 degrees pretty easily. Usually in auto-x the more camber you can get the better but it can start to hurt your straight line braking performance. The turn-in is very nice and hard now so I'm leaving it this way for a while.

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

I was running the Bridgestone RE-11's in oversized width. 275/30 front, 305/30 rear. I had to water the tires at the end of every run to prevent them from overheating, they fall off quickly when hot.
