Wheel spacers. Torque thrust ii Hows it going guys i have a set of tt2s that i bought years ago second hand the tears are ok but the fronts do not work as they hit the caliper I threw on 8-9mm spacers i had on hand and it clears however my question is are the ttii hub centric or lug centric also what lug nuts will i have to go for I plan to change the studs to ones that are an inch longer
thanks all

As far as I know, all of the TTIIs made in a GM 5 x 4.75" bolt pattern take a 60° conical seat lug nut, therefore would be centered by the lugs. Anyway, these wheels should have a hub bore diameter of 83.06mm which would not be a hub centric fit on a 70.3mm LS1 F-body hub without a custom ring.

No, just that they couldn't/wouldn't be a hub centric fit on any 4th gen F-body no matter what, unless you installed adapter rings.
I didn't use any rings for the TTIIs on my '98 Z28. As mentioned above the lugs will center them, but you can source and use the rings if you want (70.3mm to 83.06mm).

The wheels will require a 60° conical seat lug nut no matter what type of spacer/adapter you might use. If you are going to change studs to longer ones, or install an adapter with alternate studs, then you will need to get a lug nut with a matching thread size for said studs. The factory studs use an M12 x 1.5, RH (right hand) thread. If you want a close-ended lug nut, you'll just need to make sure that it's deep enough for the increased exposure of the longer studs, otherwise you would need an open-ended nut to make sure that it's not bottoming out before reaching proper torque.
