I tried searching but did not find an answer to my question. I want to know if the 18-inch OZ Ultraleggeras will clear the new JCW brake kit without any issues. I remember reading that someone was running the 17-inch OZ Ultraleggera wheels with the JCW brake kit without any issues. The 17-inch wheel has 37 mm offset while the 18-inch wheel has 42 mm offset. I did some searching on wheel offsets and for reasons that I don't quite understand, it appears the wheel with the 42 mm offset would have less clearance than the one with the 37 mm offset? I thought it would be the other way around. Anyway, is anyone running the setup I am interested in running?

 

go to tire rack and plug in 09 jcw and they should come up under the oz wheels.

 

i just checked it out and the 18'' oz wheels are on there for the 09 jcw. so they should fit.

 

looks like the 18'' only comes in black though.

 

Thanks, that's good to know! I already have a set of 18" black OZ wheels on my 07 MCS and was thinking about upgrading to the new JCW brake kit for track driving.

 

oz wheels are the sweetness

 

I had a set on mine for a while and they clear just fine. I think I still have a few pics of them in my gallery.
