lip kits on a sport c class

I know a lot of the lip kits like wald and auto couture have lip kits for the w203. but i have a sport model and i was wondering if the front lip can fit on the sport bumper or would i have to get a new one?

The standard bumper and AMG bumpers are yes, totally different and those kits will not fit on them.  I know you've seen mine with the Auto Couture aero, but it's a luxury model and it wouldn't fit on your car.  The side skirts will, but not on the front and rear bumpers.  The only front I can think of is the Eurotech carbon front lip which is made specifically for the AMG front bumper on the AMG, sport, and optional AMG aero cars.  Other than that it's either get a full bumper aero kit or swap bumpers with someone with a regular C-class plus some cash.  Then they get AMG aero and you get bumpers that can be used with lip kits..plus some cash to buy those lip kits.

thanks. youve been a lot of help to me.  Do you know how much it would cost to get the regular bumper? And kinda of off topic but what brands have a full exhaust for the benz?

Well there's Eisenmann brand from maker Eisenhaus, Remus, Carlsson, Kleemann, Brabus, Supersprint, I could go on and on...haha, there's a lot.

Lol. Damn. I must be looking in the wrong places then. I dont know if i should leave the bumpers stock and just drop it on coils and get bigger rims or try to mix and match kits.
