My mates 98 wrx runs 12.1 with very minimal mods. sti turbo , power fc , front mount , 1.2 bar. They handle awesome and the launches are rediculous. 1.6 60ft time at plex. Even a highly modded gts-t wont get near that on the street. And this stuff bout the gts-t catching up on the straights ? youd want to be packing at least 350 at the treads.
So all in all there a good car. Awesome street package in my opinion.
