Re: Cragar SS uni-lug
 

that was common on them back in the day the lugs would bottom out on the stud before pulling the rim down tight, then it could walk on the studs giving the thump at 60/65...my very first set did that and the guys at Posi Traction set me straight.

I had unilugs on an 87 IROC. The car was a theft recovery and the unilugs were on the car when we got it. I did not notice any unusual vibrations, but had 2 sets of front bearings wear out. Eventually we put the correct factory wheels on the car and never had bearing problems after doing that. I'll never use unilugs again.

I have unilug keystones in the camaro . . . they're outta balance, but it's cause the damn rim got bent . . . my brother ran the frickin thing into a curb . . .

Never had any other vibrations from any of the others i have. Maybe i'm just lucky
