Was curious how hot the front rotors were getting. Looks like they get a bit warm. Painting the pad backs and caliper piston centers for Thursday. Expect I'll see similar brake temps, data should be a little useful.

These are 18x11 EC-7 with 295/30r18 Toyo RRs up front, with a 25mm spacer. At the stock ride height there is roughly 2" of vertical clearance to the fender. Tires turn lock to lock without rubbing at 15mph. Ballpark .75" inboard clearance to the coilover, and given the slight tire stretch, I'm hoping the inside won't deform enough to rub.

A little worried that under compression it will rub the outside shoulder on the fender. In theory given the camber and the angle of the coilover, it looks like it'll tuck in. I'll take it easy on the first session, gradually add more cornering and check for rubbing signs.

This is the last goal for the car, squared 18x11. If it doesn't work out, I think M4 GT4 parts might make it possible. It'll be questionable if I go that route vs just sticking to a staggered setup and accept the front/rear tire wear variance.
If you find you are rubbing on the outside fender, you might not need that much inboard clearance. I have about 0.25" and have never rubbed the strut.
