I believe back diameter is about half inch shorter. I’m not sure how off the speedo is as I haven’t checked against gps. Ive run MDM which was very intrusive. I’m not sure if the diameter difference had an effect. Traction control totally off and the car is awesome!They are holding up great! I’ve only been out 2 days at road America, and 2 days at Road Atlanta. No fade. I have revozsport brake ducts off my base m4 that I haven’t installed yet. That’ll be a winter project. Current project is installing a set of OMP WRC carbon seats and harnesses. I hope to do a couple track days in February at COTA and Sebring.
