I run my MY04 in A Stock autocross. What wheels are available that are lighter than stock and qualify to keep me in A Stock? As I understand the the rule, the dimensions have to be within +/- 1/4 inch of stock.

 

Look in the S2000 Autocross FAQ. There is a link to a thread that discusses all the wheel options for the '04-08 S2000.

 

CCW has made some for s2000 owner who were convincing enough.

Kosei has some K1-TSs for the fronts 17x7 +50

TRM F3s by the tire rack make stock sizes as well.

Tire rack also made a deal another wheel maker to make a set of oem sized wheels for about a year.

Team Dynamics also offered some wheels within stock limits for the front.

The 97+ NSX 17" rear wheels will work for the rear.

Thats all I can come up with for now.

 

there isn't very much offered in a after market wheel within 6mm of stock offset, and then in the rear its a lot harder to find a wheel. You are better off trying to find a set of nice wheels for the street, aftermarket or something and use the stock wheels for your race tires. OR you could get another set of stock wheels from someone and put race tires on them.
