Is E85 an option? I would think your only a set of cams and a tune away from the pointy end, figuring the weight removal as well with the fuel change. I just feel the car is really good but over developed for 5. To be on the pointy end of 5 (imo) would take quite a bit of changing parts out - going back to stock brake calipers, stock arms, none spherical bushings and shock change, at least from my experience. Plus I am biased towards more cars in 4
