magnum wheels wiwood brakes

I sent Wilwood the measurements for my 15" Magnum wheels ,which the inside measurement is 145/8" and from the stud hole to the rim is 5 1/2".the kit that I am thinking about buying is P/N 140-11020

Any opinion and help if this kit will fit with the Magnum 500 wheels would be a great help.

Also is there any other measurements I should be looking at.

BTT Wow nobody got any info

Just want to tell you that Wilwood customer service is pathetic including their technical knowledge (can't say what I really want to on this board). I have Wilwoods on the race car front and rear and never again for me. Anyone but Wilwood...........

Can't help. I have magnum 500s under the Master Power Brake rotors. Had stock discs but switched em out. The probably have a skeleton holiday crew.

I have an older kit, 140-2721-B. Size and clearance wise, it might the same as the kit you are interested in (10.75" rotor, .810" thick). Mine fit the conventional 14" Ford rims I have, but not a 14" Chrysler rim. The sales guy was no help and provided mis-information too.

Because I knew I was close, I made a fixture from their cross-section information available on line. Made the fixture, and fitted it to the rims before I bought them. I can send you a picture if you want.
