Well since my car is getting an fmj disc spindle swap I started with a set of spindles and rotors. as you can see from the picture the rotor is well used and I found out that it was actually warped which made for difficulty machining it.
So I chucked it in my friends lathe, covered the ways and ground the disc portion off
So Machined it to accept the charger wheel speed sensors off the fronts. and turned it into a hub. So I uses the factory charger wheel studs and sensors. uses the factory fmj wheel bearings. and has the 5 on 4.5" bolt pattern.
and as you can see in these last 3 pictures I have placed the factory charger 12.5" disc brake on the hub and will be building a mount to use the factory charger brake caliper.
