nice one diles, all you do is ask a simple question and you get nothing but abuse. if i had the money i still would not buy gruppe m, doesnt justify the price for the gains and you have to cut into your scuttle panel to fit it. surely for that price you shouldnt have to cut anything........ also read a few people getting rattling coming from them as well. that kind of money could be spent on other mods.
