I was thinking that running 18s would be nice for the winter and I like the idea of the Aeros to try and optimize the range as much as possible. So, the MPP rotors are 4mm thicker plus 15mm spacers minus 5mm for the more poitive offset of the Aeros, and you moved the wheels 14mm to the outside of the car. Any idea what impact that had on the range?I was running MPP Page Mill disks in standard M3P sizes (355mm) + M3P calipers and Bonoss 15mm spacers on mine with Aero wheels for every day use absolutely no problem. No grinding necessary at all. I know that the MPP disks are slightly different than the standard ones (and way better heat management + lighter) vs offset.
