I believe you can have a shop put the weight on the inside but I don't think you can do it yourself as putting the weights on the inside right across from where they were outside may change the balance. However, anyone who does that must be very careful and experienced! I had the chromed wheels on my Firebird balanced last week and the mechanic ripped off a piece of chrome when taking off the weight. I had to go back to the dealer to have them order a new rim for me. Also, these cars usually don't require wheel balancing. I'd leave it the way it is from the factory if I were you.
