I think I remember someone say 15mm front and 12mm in the back is the goal on the 45 offset JCW wheels. How are your vehicle regulations in terms of modification?
Does anyone have any advice on how thick the spacers can be if I put 215/40 - 18 non run flat tires instead run flat 205/40 on JCW Cup wheels. Standard suspension, Mini JCW convertible 2017.
