The wheels are take-offs from a 2012 Boss. They are 19s, the backs are 285 x 35, the fronts are 255 x 40. I like the eibachs, I have not bottomed out on anything, the ride is good with me. I have not had any rubbing at all.. I was originally wanting to get RTRs or the TSW nurburgring, but they ware on backorder for a long time, but I was going to wait. Kent from Evolution Performance sent me a e-mail on a Friday, letting me know about the complete take offs from the Boss, I went up to get them Sat morning.. I really like them, they seem to get a lot of looks and complements ..love the wheels! what are the specs on them? how do you like the eibachs? do you feel that it is too low for a DD? any bottoming out yet, or rubbing on the wheels?
