5x4 3/4 is the spacing.CMNTMXR57 said:All that stuff was tire size I believe. I don't know any of the specs on the wheels. I wouldn't bet the house on it, but my guess is that they aren't too far off the 18's used on Vette's and on a standard Chevy 4.5" (or is it 4.25") bolt pattern. I can never remember.
Is there any reason not to remachine the taper for the nuts to an actual 120mm bolt pattern so people don't have to throw out f-body rims or not have the option of buying other new 120.65 rims? Christ, you only have to move the bolt pattern in about .013 radially. I figure you would have to drop the taper down about another .030 at the new location to ensure full engagement on the 120mm pattern.

5x120 does not equal 5x4 3/4...yes some have bolted them up, but it's not advisable to run them all the time...in other words, don't use fbody wheels
make sure the wheel is hub-centric and not just lug-centric...the weight of the car should be resting in the hub, if it's on the lugs, you're in for an accident
This info will come in VERY handy. Thanks, Jason.CSiJason said:5x120 bolt spacing, 48mm offset (stock 17x8's), 69.5mm center bore
Do a search in this forum for info on what you should use for wheel offsets for different size/width wheels and tires without having rubbing issues or a froggy looking retard car.

:hail: You're right. That is handier. Are all of these measurements that have been tested? If they are, you saved me a sh*tload of work & calculation.CSiJason said:This may be even more handy...

Works the same, I suppose. They have the free time to swap out different combos.CSiJason said:This was determined by the folks at discounttiredirect.com I do believe.
I certainly can’t list all the ones we’ve found to fit – but the answer is not as many as you think. The offset is European. The GTO hub has a 5x120.00mm bolt circle diameter. The offset is 48 mm for both 17-inch and 18-inch wheels. The GTO wheels have 8.0 inch wide rims.
Do these numbers apply to stock or rolled fender lips?CSiJason said:This may be even more handy...
