I am about undergo the front brake system upgrade/mod to my '86 Turbo Z. I have an '89 complete rack with stamped steel LCAs and PolyBishings from Johnny. I have the SLH 3 or SLH III complete setup for the rears ready to go on with correct proportioning valve and 24mm MC.
1. Are the ‘single’ pin Kelsey Hayes Calipers from only from a NON-aspirated car i.e. the ’89 plain model or the ES?
2. Were the single pin KH calipers 54mm or 60mm or came in both sizes?
3. Did any of the '89 Daytona SHELBY TII come with both the single pin KH in the 60mm as well as the double pin ATE setup in the 60mm as well?
4. Did only the ‘double’ ATE calipers come only on the TII cars, i.e. the ’89 Shelby TII?
5. I have a pair of the ‘single’ pin KH calipers from an '89 donor car already. I believe this would be a direct bolt on application using the caliper bracket to my ’86 knuckle and spindle, correct?
I have located a set of ’89 SHELBY spindles/knuckles all-in-one to mount the ’89 SHELBY ‘double’ pin ATE brakes to my ’89 K-Frame and stamped steel LCA. This is not going to be a track car, but I am looking for the best most efficient setup that work very well together since I have to replace the calipers anyway.
Would staying with the direct bolt on KH calipers with bracket with the ’86 pressed in wheel bearing setup be the optimum setup OR would going with the ’89 SHELBY setup changing the spindles to allow for the double pin ATE calipers and the bolt in wheel bearing be the optimum setup?
