The tire shop that mounted them did not have any trouble balancing. You should not have to rebalance them as they have only been used for about 800 miles. I had these on my 95 v6 coupe but traded that car in for my 97 cobra. The 95 coupe with these rims drove perfect, no vibrations of any kind. I dont really want these on the cobra, as i fell in love with some 18" boyd coddington's and im also in some financial trouble, so thats why im selling. There are no problems with these rims other than the one hole thats a little rough, and i already explained that.
