Wilwood rear disc kit

DEoes anyone know if the rotors that come with there kits are double drilled 4.5"/4.75" ? I want to run a set of Weld Pro Stars but the backspacing I need is only available in 4.75" bolt patern. I thought I could have Moser make me some 4.75" bolt patern axles for B-body brakes and run the rear disc kit if the rotors are double drilled.

Thanks AL, The Aerospace kit looks nicer then the wilwood too.
I see three patterns... I think you should be covered...

bblm23, which kit is that? street or drag? how thick is the rotor?
Hello, The studs for the wheel pattern are drilled into the axles. The disc hubs are drilled to fit both patterns. You will need to have custom axles made in the 4.75 pattern with the correct axle offset to match your disc brake set up.

The Pro Street kit with the parking brake. They are the thicker vented rotors.

I know, I need to have Moaer make me some A body length 4.75" bolt patern axles for B body brakes.

And just out of curiousity what size and make of wheels are you putting around those new disk breaks?? I have the Wilwood rears on my 72 Dart but my 16" Center Line wheels won't clear the calipers. So I have to find a wheel that doesn't have the step in the back or move to 17" wheels. and my car is a 440 bracket racer and you can't buy slick for 17" rims and few make them for the 16" rims. So I have this small but frustrating problem.

So I'm curious what wheels you're using.
