well i've just about given up trying to make my c 230 faster (06 sport) so i'm thinking of doing suspension work such as a front tower bar rear sway bar and full coil over suspension hoping i dont downgrade the already great stock handling performance of my car, i was just wondering if anybody has done anything this boldly different to their mercedes, i already ordered my rear sway bar from h and r and will post if i fell any difference. On a non performane note i would like to replace my stock headlights with aftermarket HID's, some people have told me that it would throw a bulb out code others say i wouldn't has any one tried this? well thanks for any feed back guys i appreciate it.
