Autocrossing - lots of fun

aaykayaaykay Posts: 539
Last weekend, I attended an Autocrossing event here in MN (onlooker not a participant). I had never attended an Autocrossing event till then, even though I had heard a lot about it. Needless to say, I am now hooked.

Basically, on my 07 WRX wagon, I have the SPT (Subaru Performance tuning) front and rear strut tower braces, slightly larger SPT rear sway bar (20mm vs the stock 17mm), and 225/45ZR17 Michelin Pilot Sport A/S tires on 17x7.5" +53mm offset 2004 STI wheels (slightly wider and lighter than the stock 17x7 WRX wheels).

I don't have any other mods (either engine or suspension). Under what class would my car be able to compete in, if I were to participate in an Autocross event ?

    Based on the information provided in the other forum (by stevecebu), seems to be the organization who manages these in the US and their rules and car classifications can be obtained from within their site.

    I just became a member in our local chapter ( and hope to join in the fun, when the next event takes place here. :D

    I think checking through the rules, my car would be placed in the "Street Touring" or STS category. This is because I have the slightly larger rear sway bar and the slightly wider rims/tires.

    However, since I don't have other suspension mods other than the 2 strut braces (like stiffer springs/struts), I am not fully utilizing the leeway provided to cars in the STS category. :cry: But let us see.
