Read so much its ridiculous. Correct me on any of this if I'm wrong.

1.). A 6.5+ backspacing is needed to tuck.

2.). Bogarts are the only wheel option with 6.5+ backspacing in a 6 lug pattern.

3.). Swapping to 5 lug gives you more wheel options. Ways to swap to 5 lug: redrill axles and hubs, swap rear ends. I heard a rumor that 8.5 obs axles may fit. Any truth to this? Any other options?

4.) If equipped with disc brakes: A 15x10 with 4.5 or less back spacing will fit with grinding the stock calipers. Anything with more back spacing than that needs the 99-02 brackets, s10 calipers, s10 brake line, pads, and grinding. Other options are a drum brake swap or a rear end swap. Any more options?

 

Pretty much correct. The only other option for the rear is to narrow it then you can keep the stock brakes and run a wheel with less backspace. From there you could also upgrade axles, swap to 5 lug and redrill the rotors, or completely change brakes, really anything you want to do. Way more wheel options in 5 lug and a lot less expensive.

 

The obs rear axles are completely different. There splines on the ends are different diameter. Was gonna pull some from an old rear end I had to fix mine a while back. Other than that everything u mentioned is correct to fit 15x10s

 

Bump for more info. Decided to get a 15x10 that doesn't tuck. Anyone know what backspacing will work with grinding the stock 03 disc brakes? Don't want to get a whole lot invested just yet. Would like to run some crager soft 8s.

 

I would like info on this too. I need to do something...

 

I'm running a 6.5 back space but I'm having to run spacers on mine because the banjo fitting is in the way of the wheel.

 

Does crager make a soft 8 in 15x10 6.5 back spacing in a 6 lug? What size tire could you fit on it?

 

Are you still running the Silverado calipers? How big are your spacers?

 

Yes the stock calipers. 1/2"-3/4"

 

Awesome! Thanks for the info man. So in theory, anything with 5.75 or less backspace should work with the stock caliper? Does the grinding progressively get worse the closet you get to the banjo bolt? I've heard the caliper is tapered.
