Terry sells the EBC Turbo Groove rotors but good luck getting a price. I've been trying for 3 weeks now! I'll be taking my business elsewhere!
Check you rear rotors. I've been feeling warpage but I think it's in my rears because when the car is hot and my KVR's get sticky and the rear stock pads fad I don't get wobble. I'm replacing the rear with KVR's and another slotted rotor advertised on the boards recently.
