I have a MSC on order. I have driven MSC's off the lot and was not that happy with the firmness. I could live with it, but a little less shake, rattle and roll would be nice. I have an opportunity to buy some 15 inch hollies at a pretty good price and understand from the forums that the stock tires on the 15 inch rims have a somewhat negative effect on handling, but the positive aspect of the improved ride quality is a plus. My question is, do all 15 inch wheels fit the 2006 MSC or is there something that you have to watch for?

 

Pretty sure they all fit, with possible exceptions for wheels with extreme offsets that would put the caliper in danger.

15inchers don't have a negative effect on handling if you use a size like 205/55/15 or 225/55 - actually the smaller diameter wheel/tire with less rotating mass improves handling. Now, if you're using 185/65/15, then yes, the handling goes bye bye. Unless you're in snow, that is.

If you really want to improve the ride of your MCS, you're going about it the right way. Start with the tires, then if it isn't good enough, invest in some softer springs/shocks. Or buy the 07 MCS.

All 15" MINI OEM wheels will fit the MCS fine, assuming the car does not have the JCW brake kit.
Aftermarket 15" wheels - most fit, some do not.
