Ive been trying to find after market wheels for my 05 c230 kompressor sports sedan but Ive been told that my year and model has an upgraded brake package so the callipers are huge and a lot of wheels ive tried dont clear them.

I am looking for black or chrome 18'' or 19'' and they have to have a staggered offset. I was wondering if anyone knows some wheels that fit my car.

Also, what sort of mods would add some HP
I've heard k&n air filter from searching the forums on this site but i dont know a whole lot about cars.

Any help is appreciated!!
