Hi All, RRS have recently completed a performance billet 4-spot caliper conversion using my 65 Riviera for the prototype. I believe it may also fit similar era full size Buicks using the sample spindle as 1st Gen Rivs. 1964 Electra for example. Also, working on same kit for 66-70 Full size Buicks and 65-66 Electra and Wildcat. Incredibly, this kit works with the standard factory booster and even before bedding in my brakes are fantastic. This kit includes: New Vented Rotors 11.86" (301.244mm) dia 1.28" (32.5mm) thick - Full size Buick 5 on 5" stud pattern New quality inner and outer wheel bearings and seals All mounting hardware (adaptor brackets with high tensile bolts) Approved Braided SS lines and mounting hardware (pair) RRS Cobra Billet Calipers custom-made for Buick (pair) I have put all the information up on our website and look forward to any questions. click here to visit web page RRS are now working on a matching Rear Disc Brake kit with drum brake built-in to the rotor that uses existing emergency brake cable so no mods.
