I have a 2003 MCS with the stock 16" X Lite wheels. Im looking to get a little more stopping power (larger calipers and hopefully larger slotted rotors) and don't want to get larger wheels. Im having trouble finding information on which rotors and calipers I could fit in these wheels. Will the R56 calipers fit without shaving the wheels? Any information is appreciated. Thanks

 

If these are the wheels you have, then yes, they fit over R55/56 S front brakes. They are tight, but they fit.

 

The R56 brakes fits with the X-lites!
