Hmm...you know Blur, I didn't think about those factors.
Well, on a track, I guess it's kinda of a given that an STi would win.
My assumption was on a 1/4 mile sort of track, and if I mod it, I would want to mod it towards a straight track. I dont' think I want to mod it towards something it's wasn't really designed for. (IE: I would want to win on the Camaro's turf

A track isn't a typical muscle car's turf )
You're also right in that you shouldn't underestimate it...I agree.
