Problems with Big Brake conversion....Help Needed
Friday, March 18, 2005 9:40 PM
Ok, heres the deal, i started by building my own rear disk conversion by getting the adaptor plates in a GP awhile back, and decided to put together my own front kit as well. well i have all of the pieces but they are not fitting together right.

I have the front spindles and hubs and caliper adaptor brackets as they come from bear in the 13" conversion kit, and i thought that they just used standard C4 13" rotors, but the rotors i have hit the bolt that holds the top of the caliper adaptor bracket, its like the offset on them is to deep, when i put an 8mm wheel spacer under the rotor, it almost fits like its suppose to?

So can sombody please clearify weather the 95+ J-body 13" track system has a speacial rotor or uses the standard C4 vetter 13" rotor?

I'm honestly not sure. It's not something they mention since most people will need to get the rotors from them anyway with the re-drilled pattern.

I know that the front rotors had less of an offset than the rear ones, if that's relevant.

Yeah, i was looking at your website and the pics of your kit and the rotors are special on the front with less offset, man i hope the rear rotors i bought will work.

well the bolt pattern doesnt matter, but they are 5x4 3/4 but have been redrilled for the 5x100 cavy pattern, this is the same thing bear does with there rotors.m unless you get the 2 piece rotors then there is only one pattern in the hat.
