production before i got to it. So i ended up with 42. I think they are tucked to much under the fenders so i would have gone with 37 (or maybe even 30) fo the fronts if i could have it. ET doesnt have so much with spokedesign to do though. I could have had 37 but still have 2mm clearing from the calipers. Yes there MAY be differences in the clearing but you cant figure it out via ET
