I purchased the AW21 wheels for my M3P, and waited patiently for my original tires to wear before installing these 18" wheels with 245 45 18's.
I do not track my car and I am not concerned about the little in handling I'm giving up, because the added range and longevity of the new all season tires from Yokohama (Yokohama YK GTX) give me an exceptional ride quality and the 18" rims by Atomic have already given me additional range. Straight line acceleration feels the same, although the staggered tires from Tesla lend additional grip in handling, which may be important for those who track, but for the average guy like me, these are perfect, and they allow me to properly rotate tires unlike the original staggered setup. The ability to clean my brake calipers is now an easy task.
Atomic Wheels got these to me in less than a week, and they were packaged well with no defects to be seen. I am very pleased with these!
