Discs on an 8 3/4?

Wanting to upgrade my stock axles on my bracket race car. Going to lbp so, I will need new wheels and brakes also. Planning on using the Speedway weld on brackets for gm metric calipers. Looking at Weld Pro Star wheels.

Well, going to LBP axles adds about 5/16" to the track width. Figure the disks will add another 1/4". What A-body do you have? What size rims and tires do you want to run?
