As said above, pug 106 205 0r 306 gti6 or rallye, I go for the 306, as you could leave the engine alone and just play with the susp, good spring and damper kit, soild top mounts, roller bearing wishbones, strut braces and a few other thing, my best mate has a gti6 and done a all this thing and more, and just setting the car up now on throttle bodys. his handle like one of the old BTCC 306 flat all the way through the bends, scares the shit out of me, I can happy take a bend a 60 in the rst and he can go though the same bended at like 90.
