Got my N55 midpipe today. Wheelspin from zero until 2-3 gear shfting @ 120kmh (75mph?) with this setup and even on partly dry surfaces >90mph...in 4th gear. Man!
Advevo put this 225/40 18 square Hankook Winterplus tyres on , the same he used in the snow with his former E90 M3. It's a blast, anywhere a tad of oversteer or totally full lock. Sound is great with the midpipe too. This is a EVO Mitsu sort of without the frontdiff or a Escort MkII on super stero´ds LOL . Greatest car I ever owned.
