Bought some 18" rims and have a question

[Ckrikos]

What a chore getting these wheels perfectly balanced. I went back to Firestone because they made the shimmy come up sooner 77 vs 85mph from tire rack. I asked if they could road force balance the wheels. They said you know just take your money back, we don't have time to diagnose your cars/wheels problems. I can take a hint. I didn't love their work so went on my way. I then go to sts and they say they can't do it but go to a shop down the road and don't tell them you got your wheels from tire rack. I go there and tell the guy I need the tires road force balanced and the wheels checked for roundness and hub centric. He also says he'll check my suspension. I pick up the car an hour and a half later and drive it down the local interstate. I get it up to 90 and It drives like a dream. It turns out Firestone didn't balance the wheels correctly as I noticed they were spun around on the rim (by the new shop) and my suspension was off a little in the rear for both toe and camber.

Their alignment was cheap too $80, can't ask for much more.
