best disc brakes for sbp
Some confusion on rotors is due to different Centric PN's. PN 120.63005 sells for $80+ and usually "not avail". PN 121.63005 that Vs29H1B references is available and cheap. Centric's website shows the later for 65 Valiant but the drawing of the earlier one (below), so should interchange. I ordered a pair from PartTrain for $61 w/ shipping in the hope I can make them fit a 10" drum conversion. If not, I'll wait til I get disk spindles & hubs, or resell.
I assume Scarebird refers to these K-H rotors. The rotor's hub register is 2.90" ID (73.7 mm). The 10" drum hub is 2.31" OD (58.7 mm). To center on the hub, Gorilla Automotive's "Hub Centric Ring" PN 74.5710 (57.1 x 74 mm) or PN 73-5920 (59.2 x 73 mm) could work with a little filing (plastic). Of course, you can also center the rotor on the studs.
Forget prior suggestion of '96 Voyager (14" wheels) 5x100 mm rotors (also Lebaron, Acclaim, etc). While they can fit over the hub and studs (grind), a bigger problem is the tophat is low, making the caliper stick out past the hub outer surface plane (where wheel bolts). My 14" SBP Cragar inside surface is almost flush with the hub. I would have to use wheel spacers to move it out ~1", and those are rare, costly, and cause other problems.
Scarebird found the K-H rotors on the 10" drum hubs don't come quite to the spindle surface, allowing room for a front-mounting spindle plate. It might be possible to fit the caliper to the drum spindle, though many other possible interferences. My 14" Cragars are 13.5" ID except within 1/2" of the hub surface where it reduces to 12.25" ID. My factory steel wheels are 13" so no discs could fit.
I would buy if Scarebird can design a spindle plate that is low-cost like his others and a bolt-up (no drill) solution. I imagine no problem scaring up 4 others. Like others, I didn't look at the earlier design because the photos on ebay and the website didn't show clearly how the caliper mounted, plus questions about the wheels fitting. I don't have a milling machine.
My preference would be 4-piston aluminum calipers (non-float). I see many Wilwood ones on ebay, with standard mounting ear spacing of late, plus adapters (~$20) that bolt to the ears. The biggest concern is that most are for up to 1.25" thick rotors so not sure would work with the K-H 0.81" thick ones. They do say the calipers work for various rotor diameters as long as the pads sit near the outer edge.
