Front 380mm X 34mm Rotor Rings for S197 380MM S550 Brake Conversion - GT - Boss 302 - GT500
This is a 380mm x 34mm direct replacement rotor ring for use with the OP Mustang S550 6 Piston Brembo Conversion Kit. These rings are a direct bolt on to your Existing GT500 15" Girodisc Hats. Simply remove your 32mm Rotor Rings and Install our 34mm replacements. These rings also correct the centering issue in the caliper and allow the removal of the caliper shims from your OP Mustang Kit.
***THESE ONLY FIT EXISTING S550 6 Piston Brembo Converted S197's Already Utilizing the Girodisc GT500 Rotor System***
The thicker rotor ring provides additional thermal mass for a small weight penalty of 1 pound, 10oz per rotor. The thicker ring also places the caliper pistons in their designed sweet spot so the pistons remain square in the caliper bores as the pads wear to the backing plates.
The rotor utilizes 72 internal curved vanes, developed in racing to act as a centrifugal pump to force cooling air through the disc.
Rings come complete with all new hardware and full instructions for re-assembly; but if you choose you can send us the hats and we will do all the re-assembly and turning of the rotors for only the cost of shipping. This service is available for the life of your rotors.
*** Price is for a PAIR of rings and 2 hardware kits. ***
*The Rotor Hats Are Marked: 30mm Min. Thickness. The 34mm Rotor Rings Min Thickness is 32mm, it is marked on the outer edge of the rotor ring. Follow the markings on the rotor ring and not the hat*
