15 stock wheels cpp rear disk brakes
 
Okay guys I’ve searched the forum and haven’t been able to find an answer. Currently have a 12bolt rear end that’s not on the truck and converting to rear disk brakes. The issue I’m having is that the stock 15” wheels 5x5 wheel pattern will most likely not work on the rear and disk brake set up. I want to use these wheels as I just got new 255/60/15 whitewall tires mounted and going for a rat-rod look. I’ve tried using a .5 wheel spacer (not adapter) but don’t think that will help the wheels clear the calipers. I don’t want to have to purchase different wheels, any ideas?

Thanks in advance guys.

Quick phone call to CPP should help confirm whether the kit you have is compatible with 15" factory wheels.

Also, what wheels do you have exactly?

I added the CPP rear disc brake kit with my 15x8 Rally's with no problem. They were the 11" rotors w/ e-brake

I have the steel 15x6 wheels with the 3 nubs for the hubcaps. Rick, I too have the CPP rear disk brake kit with the 11" rotors w/ebrake. However, the wheels definitely don't clear the caliper at all. I'm thinking I may just have to get some wheel adapters vs wheel spacers to make them work.

Really don't want to buy more wheels as I still have to get the new diff installed and the T5 I just purchased installed too followed by getting a new driveshaft made to get rid of the two piece. Just never ends and never easier than it should be. :banghead:
