|390mm x 34 mm AP Racing/STILLEN Rotor|
The new AP Racing 390 mm x 34 mm J-hook rotors just arrived in an air shipment . They are being unpacked, but I grabbed a rotor to take a couple of quick pictures. Real photos coming soon.
These are a little different than the early J-hooks. They do not reuse the factory hats. In order to make it possible to fit these rotors on 2009-2013 cars, we made a new hat to properly center the 390 mm x 34 mm rotor. The disc assembly is upgraded from 10 mounting points to 12 mounting points. Also the disc is a 72 curve vane design(48 vane on the early 380 mm J-Hook) that is slightly heavier than the stock rotor for more thermal capacity.
