I want to run the Weld Draglites, but I need to know what size wheel studs to get, what lugs, and I know the 15x8 with a 5.5bs work well with a 275/50/15. But what about a 15x10 with a 7.5bs, what tire looks good with that size. And is there any other modifications needed other than grinding the calibers? To run a 15x10. And is the correct spacer for the fronts a 5/16" For a 15/3.5 with a 1.75bs.
PICS of the 15x10 would be nice too

Someone has to know!

15x8 w/ 5.5" BS, 15x10 w/ 7.5"BS, as you have noted. To figure what size tire goes on what size rim, go to tire rack and look up the brand/size tire you want, and look in the specs to see what size rim it works for. Just about any true slick that fits under a 4th Gen will fit on a 10" wide wheel.

In the front.... yes 5/16" spacer with 15x3.5", 1.75" BS. Weld will tell you the model number for their lugs... "Extra long shank, mag-style with washer". For stock studs, you need 12mm threads. Lingenfelter and GM Performance parts sell a 2.67" knurled stud for the 4th Gens. It will just barely pass NHRA tech. Unfortunately they have more than 1/2" of extra unthreaded length on the ends, and pretty much limit what you can do to put a "normal" wheel back on the car, at least with closed end lugs.

In the back, grind the fins off the brake calipers. The 2.67" knurled studs should be fine in the back, since there is no spacer. I run 3" 1/2"-20 on my Strange axles.

The picture below "Trailer Queen...." in the sig shows 15x10 7.5" BS PRo-Stars.
