Started set-up on the new Billet Specialties f body rims. The fit is awesome with no mods required to the calipers. Actual clearacne is about 1/4" all the way around (pic. makes it look a tad tight)
To those who have replcaed studs, does anyone know the original knurl dia. of the late model c4 (either in mm or inches). and or the actual hole dia. of the flange/hub? here's a couple of shots..note the shims on the hawk pads failing again.....

Thanks guys
sizes are 15x4-2.25 b.s., and 15x10-7.5 b.s. Mine is a 90 (later offset) so they were the 56 mm b.s. on the a molds. I'll be knocking out the studs tonight. It appears that there are a couple of numbers for the knurl dia. I'll know more when I actually measure the flange hole and the original studs...hopefully. |

Wheels look nice, Mick.
I looked briefly, but all I could find were part numbers, no real dimensions other than the stock length is supposed to be 1 5/8" and there are a bunch of aftermarket studs - arp,drm, etc. ARP lists them as 12mm x 1.5 pitch. GM #9591291  Matthew |

Thanks Matthew,
The issue seems to be the knurl diameter. According to most GM numbers it "should be" a .509. After removing stock studs what I'm seeing on a used stud is approx. .497-.505. I'm guessing with compression of the knurl it will lose .005-.007 dia. The original hole size with spline is difficult to determine it "looks like".492-.497 but definetly not .500 ? (length is easy am going to use 2 1/4") |

Wheels look great man! I don't have any answers as far as stud dimensions, but the wheels look awesome. Can't wait to seem them powder coated.
