Tom the 20mm in the front made it look like it should(although it felt like the turing radius was affected slightly), brought the wheels more flush with the side of the car and rubbing was NEVER an issue (lowering springs and konis) if i were to do it over again i think i would do 15mm up front and the much needed 25mm in the back. I think that would be just right, b/c the rears with 20mm look like they could use more as there is still room to fit with the way the body curves and bulges in the back
