Yes we do still have them for a good price (it has gone up a bit, as have most Porsche parts in the last 6mos.) to $302 each, it's still comparatively better to the PCNA rotor at about $400 each. Normal observed longevity is the same, high performance braking has yielded normal wear signs at near equal rates.
See you Friday for those going to T-Hill.
