I have a 2008 Cooper S with the JCW Body kit and the JCW Tuning kit installed by the dealer when new. I just purchased the car three weks ago and want to put a JCW big brake kit on it...It currently has 17" cross spoke 98 wheels from the factory...I'm told the big brake kit will not fit these wheels? any reason why? they are 17" or does the caliper hit on the face of the rim? can I install wheel spacers? I personally love the looks of these two piece design wheels...
