I got the itch to try and fit the set of Prostars I have on the Cobra. Well I've pretty much cleared the tie rod and spindle part. The problem is with the wheel spacer I have, the rim will not sit up against the hub. The stock wheel studs stick out past the spacer and don't allow the back of the rim to sit flush against the hub. So my question is.... Is it possible to shave/grind down a 1/4 inch off the wheel studs. It's the part where there is no thread on it. If I were to take it down to the fist outside thread it would sit flush with the spacer. Would this be safe?
