I've had an ATB from Bernie since september and it's coped with 530 brake with my GT30 without any dramas, did 'Coombe and gave it a proper spanking and it behaved brilliantly, do-nuts no probs, who ever said they don't do them must be dreaming. Did the Daddy thrash with GT35R circa 610 brake, still no problems ( wish I could say the same for the engine

)
The ATB is maintenance free once fitted, the Gripper will need to be stripped and serviced, new plates ect.
