The stock wheels on my Mach 1 look at bit tucked in on the the back. I like the stock wheels, and would simply like to move them out a bit with spacers. I'm going to do some experimenting to figure out how far out I want them. At this point I'm thinking 1/2".

Great, but moving the wheel out means a lot less bite for the lug nuts. I was told that for a street car, the thread engagement should be 1.5 times the diameter of the stud to be adequate. This is not a big HP car, and will not be tracked.

A) Is the 1.5 times diameter figure quoted above accurate?

B) If I do need to install longer studs, is there any reason I should not trim the end of the studs so that closed end lug nuts will fit properly? (I don't want open ended lugs.)
