MONTE CARLO 1987 MC SS RIM BOLT SPECS

[The Last Don]

Hello, I am looking to order some rims online and am not sure of the wheel size and bolt specs. I am looking at 18x8”/5x4.75 - will these fit my MC?

Theoretically, they'll bolt on, but will they clear... depending on what size tires you use.
Do you have all the specs...backspace, offset, etc.?

4" BS would work better in back. 4.5" will work fine in front. What size tire will you be running?

To be honest I dont know what would be best in this situation. Suggestions? I want to move away from the 22 inch rims - want to get more rubber for a smoother ride.

255/40 18's will be close to stock height @ 26" And should fit all around with minimal mods and maybe a small spacer in back.

If you had a 9" rim in back with a 4.5" BS, a 275/40 would be 27" tall and would be about the largest you'd want to go without mods

So what would be the ideal setup? I dont know a whole lot. I am learning, soaking up as much knowledge as I can. Reading a little and watching some videos has me concerned about not using the same rim/tire specs as the stock setup. But, I like these iroc rims! The current tire and rim size is 245/30ZR22 92W - they look damn nice but the ride is so shitty... There is no spacer in the front but the rear, it has a 1.25 inch spacer. Front and rear tires are wide - I measured the tire and it seems to be 10 inches wide - like the way that looks - but when I turn it all the way it rubs...
