Okay, so here's what I've got. Car is an 84 Monte Carlo, front has 2wd Blazer spindles with 2 piston calipers and bolt-in bearing hubs, still has 5x4.75" bolt pattern. Rear is currently stock, 5x4.75" axle flanges.
Wheels are factory BMW from a 2001 540i, 17x8" with a 74.1mm hub bore, 5x120mm lug pattern.
I realize that some guys are running this lug pattern wheel on a 5x4.75" lug pattern, but I'll not be one of them. I realize a lot of guys have no problem, but I'm not taking the chance on the .6mm misalignment. I'm ordering adaptors this week, that are 1.25" thick.
So here is my question, I believe the car was lugcentric with the factory wheels, but I know for a fact the BMW wheels were run hubcentric on the Bimmer. The adaptors I have found for this combination have no hubcentric provision, except for the hub bore, which I could machine a hub slug for to run the wheels hubcentric on them. But, should I? The only reason I am wondering, is that I've always thought hubcentric or lugcentric depends more on what you're bolting to, than what the wheel is. The BMW application uses lug bolts, which cannot effectively center the wheel, but I'll be using lug studs with nuts, which I believe should serve me fine.
What do you think?
