tr motorsports c3
So just picked up a set of tr motorsports c3 with 255the rs3 for my ap1. He gave me spacers for the front and rear. .190 for the front and. 160 for the rear. My question is when I went to fit the front I don't have the lug nut thread that I did before and its a little of a concern. Do I have to run exte nded wheel studs to run this? Or is it ok. Or do I even need the spacers???

Ok. Seller said that without them the front would rub on the control arm??? And noticed the hub is way smaller the the center of the wheel. Will I need to buy hub rings to center the wheel up?

With enough camber, at full lock you may get some rubbing on the control arm (I do with -2.8deg up front) But if you run the spacer you will need to do some fender rolling. Personally, this car has such a great turning radius that you really aren't giving up much by having to stop just shy of full lock, so I'd leave the spacers off.
As for hub centric rings, you definitely cannot go wrong with them but there tends to be some confusion as to what they do. They actually have 0 effect on where the weight goes. Contrary to popular belief the weight transferred by the wheels goes to the hub via the friction caused by the lug nuts clamping the wheel to the hub, the weight does not go through the lugs with or without hub rings. So, why do people use them? Their primary purpose is to make it easier to make sure the wheels is mounted flush and centered. because the lugs are smaller than the holes they go through, it is theoretically possible to mount the wheels off center which can cause a vibration that combined with the now improperly seated lug nuts, can cause the lug nuts to come loose. With the proper conical lug nuts in the conical hole on the wheels, and proper lug tightening, the wheels should mount centered every time anyway, thus eliminating the need for the rings, that said, they add a layer of safety with no notable down side to using them. So bottom line, although they are not absolutely needed, they are inexpensive and are never a bad idea.

There are enough threads about broken studs from people not running centering rings that I wouldn't go without them.
edit: I Autocross the TR Motorsport C3s with no spacers, and no evidence of rubbing the control arm. I'm not lowered and no camber kit, run with the suspension set to max stock camber and max stock caster.
