Disc Brake and Lug Conversion

[Billett]

I posted this in my project thread as well, but I thought I might get a better response here...

I just bought a set of steelies from a late model silverado.



Just by looking at them I had an inkling that they wouldn't fit, especially with the offset, but I got them for $50 for all four with tires so I couldn't pass it up. Got them home and they wouldn't fit, no surprise, so I was thinking of selling them out at Carlisle but then I remembered another set of rims I currently own...



These are a set of 17x9.5 C5 corvette z06 rims. The tires on the steelies are 275 so I know they will fit on the c5's. However the c5's are obviously not the right lug pattern. They are 5x4.75 so even if I did the later model disc swap (5x5) it wouldn't work right.

My question is this; I want disc brakes and these z06 rims, but I don't know what route I should go. I recall seeing a brake swap kit that changes from 6x5.5 over to the 5x4.75. I also know there are plenty of kits for regular drum to disc with the same lug pattern and also the later model swap to the 5x5 pattern. With any of the ones above I would need some of the billet adapters for the wheels to fit. Discs on the rear would be nice also, but again I could just use the adapters if I needed to. The adapters themselves are 2" to 2-1/4" thick so that gets rid of the problem of the offset and tires rubbing, hopefully. Also my truck (supposedly) has a 2" drop with aftermarket drop springs, but stock spindles. I don't know what the benefit of drop spindles over stock would be aside from the fact that some kits need drop spindles. I am assuming it allows bigger rotors but please fill me in!

What seems to be the best approach? I know several people who run adapters on their s10s in order to fit vette rims so I am not worried about the safety of using them, but practically will it be more beneficial to have one lug pattern over another on the actual brake rotors? I apologize if this seems like a simple or dumb question but I haven't worked with brakes much aside from bleeding lines and changing pads. Any criticism is good criticism as far as I'm concerned. If it's a dumb idea just tell me up front haha
