Hey guys just got out of my C230 coupe,and bought a C32,and wanted to get started working on it.
The main Question is can I fit 19's on it without rubbing?,and it is not lowered.
Besides Renntech where can I get a pulley and ecu upgrade?

Yes and Evo Sport or Brabus

what kind of springs could I put on it that would not drop it to much?

There are many vendors on this forum.
All the spring kits for the W203 are pretty conservative.
H&R Coilovers will be good if height is a major concern..

Calrsson and brabus makes a kit for the C32. Which you can get from me. You will not rub with 19's if the offset is correct. And If you want a drop that is not to much by just springs, eibach lowers the car a little less then H&R does. Neither of them will look slammed if thats what you dont want it to look like.
