[quote=paradocs98;12344365]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.


I changed out my 380mm Stoptech rotors well before the wear limits due to the surface cracking starting to go right to the edge.I had about 18000 kms and 20 days on them.I only used Pagid RS 14 & 29's with these rotors on track.Cheap insurance to change the rotors before you get full blown cracking issues.
