I recently read some of the forums here and thought it might be worth joining. I own a MY04 wrx with minimum modifcations eg: rims, stereo, turbo back exhaust.
My mate and I recently went to wakefield park for a track day to test the performance of our cars before doing any major mods. We thought this would be a good way to find out what can be improved, I recommend it to all! its great fun.
Will bother you with questions in another thread as this will be too long otherwise
