Luke, they are a top notch rotor to say the least. Well worth the coinNot a floater like the PFs but X3E rotors are also very good, they too have a curved vane designWith an alloy hat, just gives another option
Rear 300mm brembo rotors and twin piston calipers would be a nice match for the APs I reckon, only requires a redrill to 4 stud and a custom/Techsport/racefab bracket.
Out of interest how thick are the front rotors on the AP kit?
They seem to run quite thin rotors considering the size, might be to keep the weight down?
