I know this is a late reply but for anyone else...
Unnatural does it for $50 a fender, did a good job on our old S2000.
Speed concept, I don't know.
Ground Zero does it but they are a crappy shop and I will not be going back there. They got a new Snap-On impact wrench to do some work on my IS, took 4 extra hours to do the work and charged me for it even though it was because they weren't prepared. THEN they had the damn nerve to say "at least we didn't charge you for the cost of the new snap-on" WTF is that?!
