Heres the wilwood numbers
rotor wil-160-7105 L/H (needs L/H for correct cooling when mounted on front of diff) 12.00" dia. smallest I could get. I will run a loop type guard. 89.00 ea
Hat wil-170-3149 (shallowest hat they make) trying to keep rotor close to diff. 75.00 ea
Bolts wil-230-0150 13.00 kit for one rotor
Calipers wil-120-4997 (billet, because I dont like the cheaper ones with the crossover lines) 125.00 ea
Pads-I cannot remember the wilwood number, but I call their tec. line and explained to them what we were doing and the problems we were having and he recomended one of their special compound pads. 45.00 4pads
The brakes are mounted on the front of both axles, so to clear the Howe double ended steering rams (like Camo's). Had I done it again I would have called Station, and saved some $$$$$$.
I milled some T6 allum. to center and space the hat to the pinion yoke. I have seen some pinion brake jobs and they were "centered" with the yoke bolts, worked but a bit wobbly.
I used the rockwell yoke and original driveshaft yoke for the rear. Milled the allum. and the yoke to fit together inside the hat. Then milled the hat to fit the driveshaft yoke. The spacing between the two was .350. This put the rotor about .200 from the housing. I used the same spacer for the front.
The cailiper bracket will be 3/8 steel plate attached to the pinion bearing retaining bolts and the caliper. (haven't test fit yet) might need slight machining of the bracket.
