Just run 5/16" spacers with conical shank lugs and you should be set. Make sure you get the proper backspace too..

With my fronts, I run a 1/4" spacer and stock lugs. I'm pretty sure mine are the Summit Stars (basically the same thing) though. I also have 3" studs just to make sure there are no issues with the studs.

I run spacers due to ls1 front brakes. I never even tried to bolt them up to lt1 brakes. I apologize for forgetting to mention that.

You should have gotten 5.5" BS for the rear. Your going to need rear spacers now with the 4.5" BS you ordered..

^^^ Those tires are 28" dia, what are your goals for this tire/wheel setup? Going racing or just looking badass on the street? What trans and rear end gears do you have? This info is important when determining what diameter tire to run for best performance.

I would go with a 275/50 15 tire. I run the same size but a 10" wide wheel with 7.5" BS. It's the same diameter as stock (more or less) and works great with a 3.23-3.73 gear. So if the rearend is still stock you're ok with stock diameter tires.

I would still suggest the 275/50. The 275/60 is a 28" tire that balloons under acceleration. This will cause slight rubbing, usually around the back if the wheel well on the bumper cover. The 26" tire doesn't grow enough to cause problems and will give a bit better acceleration down the 1/4 mile. The 28" is good for bringing up the mph tho. I too thought about going to a 28" tire, but I don't feel like clearencing the body to keep my et the same with a bit more mph. I like my 12.9's at 103 before the gear swap. Once the snow melts I should be right around 12.7's at the same mph. Unless you want to put 4.11's in the rear I would stick to a 275/50.
