The right front rotor was at ~29.00, and now it is at ~28.90 (28.4 is the minimum thickness). The left rotor is more warn than the right, not surprisingly, by about 0.1mm difference. The measurements were consistent at the outer, middle and inside measuring at 8 locations (every two drilled lines).
The rotors are 30mm out of the box.
PS The car passed 066666 last night on the way home...  . The new M3 can't come soon enough. I think I will pass on the Lime Rock Special Edition E92 |
Good info for comparison--thanks for posting. I'm on my original rotors from my StopTech ST60/ST40 BBK. They've seen 16,000 miles, about 20 track days, two sets of StopTech Street Performance pads, and have used up half of the material on a set of Pagid RS29s. Since I change my tires for the track and have access to the rotors, I decided like you to get a quality digital caliper to measure rotor thickness routinely. The fronts started at 35 mm and are now at 34.1-34.2 mm. StopTech recommends replacing them after 2 mm of wear, so at 33 mm.
As far as the Lime Rock Special Edition goes, I think BMW missed the boat by releasing it in fire orange instead of lime green. If it were green with black wheels and accents, a la 997.1 GT3 RS, I'd be all over it. Oh, yes, and if they would equip it with coilovers, proper brakes, a half-cage or rollbar, CF fixed shell seats, harness mounts, and strip 400-500 lbs out of the car...
Glad to see you'll be ordering the next-gen M3. Schroth has been waiting for you to sell your E90 so they can finally release the QuickFit Pros.
