Default Autox setup for SC car

I have started autox this year. MY01 with Vortech SC and Kumhos on stock rims. Otherwise completely stock. Oversteer is sick and will order a Comptech bar soon. What settings on the bar should I start with and what other set up things should I address? I have reviewed the Autox thread that is a permanant post but am in SM2 class. Not sure if it is the right class either.

I'd start with at least the middle position on the bar, if not full stiff. What alignment do you have? That will make a lot of difference. You may also want to consider the 265/45 for the rear, especially with the extra power.

Of course, the real difference is the nut behind the wheel. Get all the seat time you can get and do any autox driver schools you can find. A lot of handling problems can be traced back to less than optimal driver inputs...

BTW, SM2 is right for an FI S2K.

Thanks for the setting info. I did the Evolution school in Kansas in April. What a great learning tool! I agree that seat time is the best. The alignment is stock. Tires 225 50 and 245 45 V700.

I'd strongly suggest more negative camber for both the front and rear. Conservative settings (to minimize street tire wear) would be -1.0 front/-2.0 rear. You will likely want to have more but the exact settings vary. The thing that will make the suggestions in the FAQ invalid are when you start doing big suspension mods. You may want to investigate the mods by the serious trackers here to get a jump on the theory. Of course, buy a rulebook so you don't mod yourself out of SM2...

I have read some posts about the alignment. Thanks for the great information. We will have the car on the alignment pit to install the bar and will set the camber to your numbers. I bought the rulebook at an autox today (sunday). I appreciate all the help I can get.

I'm thinking of getting good sway bar like comptech's adjustable one, but most likely I want to deal w/ a better alighnment for the time being.

I really need an alighnment suggestion for my s2000 b/c my car has mad oversteer. I'm getting one this saturday or next. b/c the bayarea section is going to do a group deal thing. Heres some info if it helps. My car has:

Supercharger
4.57 gears
and it's lowered on stock shocks w/ kg/mm race springs about (35mm drop).

The alighnment settings currently is stock.

What also doesn't help me much is the tire setup I goofed up at buying 205/55-16 front and 225/50-16 rear wrap in potenza s03's. ( i just read that thread )

I need a new set of rear tires too. The fronts are okay, but any suggestion would be nice. I'll tri to pick up a new set before the alighnment day

I like to autox my car too. My car is my daily driver. So mabey a suggestion on a good "road racer" street alighnment , or autox alighnment. and/or the best of both together.

Sorry to overwhelm you guys w/ this question. I apreciate all you help and advice.


Thanks.

"Mad oversteer" may be power- or driver-related. If you're in the powerband of the SC, your choice is to back-pedal a little on the throttle or change your driving style to minimize any "snap" movements leading to loss of traction. We can all get our cars to oversteer if we aren't smooth on turn-in and/or power application. An alignment may help with this if it's cornering-induced but I suspect you just need to work on avoiding movements that cause the oversteer in the first place.

Your exactly right, I agree! I do tend to oversteer my purposely just to have fun around turns. But, sometimes when I'm in a "rush" to go somewhere, I can't go fast w/out worring about the tail whip out in front of me around the corner. It's like I'm over the edge of being "alert" (if that makes any sense. ) So, i'm "babying" the gas. It's still fast going around the turns, it just doesn't feel right holding back. At first I had a hard time controling the oversteer, but I've gotten used to it ever since the last couple autox's I've been to. A couple friends suggested an good alighnment is a start and pretty cheap. I was even thinking about a front sway bar. So any advice on an alighnment setting suitable for my setup would be great.

I appreciate your help.

Thanks!

Hey PJ,
I told you about those tires like 3X in the last 6 months. YOU ARE UNDER TIRED.
And if you get the front bar you can move the 225's to the front and get 245/45-16 for the rear. Go with the Saner bar. It has great balance on the softest setting with the above tire combo. PM ludedude for more details.

If you are getting power on oversteer, you can correct this by having a lighter foot. It is going to happen with the SC. You will probably also see inside rear wheel spin with the front bar in an autoX or track situation so it is a trade off.

Send me a PM

Sounds to me like you're getting used to oversteering as a normal condition and having trouble backing it down a notch. I can certainly understand that the desire to go fast is always there but "fast", whatever that means, may be "too fast" in certain situations. I drive harder than the normal bloke on the street and people have no problem telling me that. However, there's few times I attempt to oversteer just for fun on the street. It may primarily be due to the desire to stay off curbs but it does keep me in check. Having someone do something stupid in front of you when you're at 11/10ths will be, umm, problematic.

As for places where it's totally appropriate to hang yer butt out, a front sway bar will certainly help and some additional rear negative camber might, too (I'd start with -2.0 deg and 1/4" total toe-in for the rear).

One question - is this BOTH wheels spinning or just the inside?
