The pads still had a some wear left in them but the rotors have some big cracks after yesterday at the track.
The tight and techical Streets of Willow track is perfectly suited for the 986 and I was probably a bit too hard on the brakes in the process of leaving a GT-R and a Mustang GT500KR behind me. Also probably overdrove the brakes during the coaching sessions with an ex-Indy Car driver.
Cracks like this are the Achilles Heel of any drilled rotor, especially on a car that sees a lot of track days, but I like the feel and additional cooling that a drilled rotor provides.
Of course, I knew this was coming so I had a set of new rotors and pads in the garage. Spent a couple of hours this afternoon doing the change out and all is well.
