Is there any chance in hell that a set of 15" 8-lug rims would clear the brakes on my '00 2500 Burb? Maybe some mild grinding for clearance? I was thinking of running a set of 15x8's with 4" backspacing.

Where are you going to find those wheels?
I have been looking for a few years and I can't even find them new

I've got a set of them, not sure how old they are or the maker. I got them as extras with a truck I bought earlier this year. Just your basic 'wagon' type wheel.

I really wanted a set but now I have a set of 6.5" wide that are trailer wheels
 
I have a set of 15x10 8 lug 4" B/S steel wheels
with DIY4x4 bead locks mounted with 44" TSL's on the crawler...

D60/14bff with disk brakes on all 4 wheels.

They took a little bit of grinder work on the calipers but nothing excessive or unsafe...

As far as IFS ,,, I don't know about the
clearance issues of the suspension and the sealed unit hubs...
Never messed with an IFS truck.

maybe borrow a wheel from a friend and try it ?? :dunno::dunno:
 
If you have the wheels, test fit one on front. Less backspacing would make it easier, but you can always grind on the caliper a little bit to make them work.
 
Back when I had my 97 2500Hd, I had a set of 15x8 8 lug with believe 4” b/s, but been 20 years so can’t remember. But they fit just fine front and rear. The truck was pretty much a 1 ton, had the 454, 4l80, full float rear. Fit fine.
 
They will fit with minor grinding on the caliper and possibly a little clearance to to the ball joint castle but or the tie rod castle nut . It’s been a long time ago since we did it.

I have some 2.5” BS 15x12 wheels here at the house I can test fit one and see what it looks like
 
Sounds promising! Sorry about being lazy, I just was avoiding getting the rims dug out before I knew if they may work. Sounds like a test fit is in order.
 
Summit shows at least 20 different 15" wheels with 8 lugs that are in stock, and probably 20 more that are 2-4 weeks out. I've had four different sets:
-2 sets of 15x10 w/ 4.25" backspace - used these on an 8-lug 10-bolt front and 14FF rear, required moderate grinding on the front to fit. Bought one set off of Jegs or Summit, and the second set came with a used set of Swampers I bought. One set was white spoke and the other chrome spoke
- 15x8 w/ 2.75" backspace - used these when I went to a D60 front, required just a few touchups on the caliper to clear, basically cleaning up the casting flash. Bought them from 4 Wheel Parts and they are black modulars, and are a reverse backspacing wheel (meaning the rim shell is reversed, when you mount the tires you mount them from the backside of the rim now)
- 15x10 w/ 3.5" backspace - these are beadlocks that came with another set of used tires I bought, so not sure what brand they are...but they were bought as beadlocks and not the hillbilly weld-on beadlocks or anything. These required light to moderate grinding on the D60 front to clear.

I used to find them all the time 3,4 years ago.
I am not going to tell my story again about 4wparts and the 15" wheels...
