Attneded second autocross, ran this time for the first time.
I went to the autocross at Castle Airforce base in Merced, Ca today and it was my first time running and it was a blast! I used my 97' with middle of the road tires (Daytona somethings 205/55) and an alignment 1.5/2.0 camber front rear and 1/16 toe in rear and 0 front. Otherwise, it is bone stock with ac/ps. First run got a 1:068 2) 1:072 3) 1:025 4) 0:589 5) 0:585.
There was also an FM2 turbo miata driven by the national champion in (?) class and his best time was 0:45 with slicks and a passenger. Overall it was a very positive experience and the tarmac was A++ being part of an airstrip ... very smooth and grippy. There were 3 karts running and those were nuts to watch. Also a completely (like freaking everything!) gutted BMW M3 with an LS1 motor and wide slicks, among others like a few formula modified cars, which were basically 2.0 4 banger F1 cars with 200 hp and 1000lbs!
Now, more than ever, i cannot wait to get my turbo miata up and going.

Be warned... I wish I had another almost stock miata to run in STS2. It really was just more fun. Autoxing a turbo miata with street tires and a VLSD is plagued by one tire fires out of every corner. Also, I was very competitve in STS2, whereas in SM2, my car is ridiculously underprepped.
Maybe I'll have more fun when I get a proper LSD and some slicks.

Actually, the open diff will help you not to spin since one tire won't have power and lose traction. You will do many corner exits with one tire smoking though.
A big front sway bar will go a long way. It may also help to remove the rear sway bar to allow both rear tires to stay planted.

Thanks for any advice!

I have helped a friend set up a STS2 1.8 w/ an open diff and we ditched the rear bar and went with a RB 1 1/8 hollow front. The car has 650# front and 450# rear springs and is very neutral. The rear tires stay planted better than my R package w/ a torsen with that setup. A well setup car doesn't need a rear sway bar. Go back to the OEM bar if you have too much understeer with no bar, but there is no need for a larger than stock rear bar on a miata unless you are trying to drift.

I have already given some thought to my turbo setup as far as handling goes, and already have installed a FM front swaybar, and have KYB adjustables. Im leaning toward the cheapo ebay coilovers and nice nice rubber to finish off my suspension. After that, probably gonna lay off the mods for awhile. Ill be running a 90' open differential which I have heard are a bit stronger than the those made later on. I sure hope so.
