Ok but the difference cannot be that big or? From 178 to 181 ? From stock to 181 I can imagine. Btw, it is 64,7 mm

hence better than 178. Also is it possible with 63 mm? The old c3 is 65mm I guess?
Btw you knowing the mercedes mkt, how much is a amg like yours in White ? Are there any? Would like to get one for the gf.
