I have some Speedway GN hubs & some 4 piston Wilwood superlites & I am looking for hats & rotors for this setup to complete my 9". Since the hubs aren't hatless I called speedway & they said to call Wilwood. I called Wilwood & they were less than helpful. Is there a common setup that a lot of you have run with these hubs as far as hats & rotors & who can I buy it from? It's going on a ranger so I'm guessing a 12" rotor is sufficient.
