thats a tough one. you mean there is no custom front rotors that will fit the one off front hats? so you want to get away from the floating stock front rotor? i would say , the only way to do this is to get the hat and rotors from him. worth it in the end. huge difference in life with RB.COM's set up. as far as the rears, i dont know the offset , but i would think he has those, but i still use the stock solid rears and never changed them, other than using drilled rotors in the rear. they last a long time due to the bias being mostly front anyway... even on the 911, , although more than the 928, it should be fine for racing. i would focus on the fronts and wait until something turns up on the list for sale for the rears for a two piece.
