I live in Stockton. I got them mounted at a buddy's shop, but most places are cool with you bringing your own wheels and tires to mount and balance. I can't imagine them having a problem with it. Cost me about $85 to have them mounted and balanced and another $60 for alignment.
I don't notice any extra road noise at all. I make regular drives from northern CA to southern CA and the wife and I are perfectly comfortable. If anything there is some wind noise from the rack and LED bar. I've had them on for over a year and the tread is still looking great after quite a few...
You should be able to fit most TRD wheels, the only issue is the tire size. I know on my 07, on stock suspension I couldn't run spacers with my 265/70/17. Without spacers you should be ok, worst case is you'll have to trim part of the front wheel liner or move it forward.
Finally able to contribute to this thread. I've been on the hunt for these wheels for a while and I finally found a smoking deal on a brand new set of these from TRDshop.com.
Needless to say I'm loving the updated look, and have been getting a lot of people asking me about my set up. Enjoy guys!
Sorry for the lack of info. I'm a bit of a noob at all of this (my previous experience at modding cars involved lowering them. Haha!)
Either way the 5100s would be set at .85. The end result is I would love to have a mild lift. Nothing crazy as the wife drives the T4R as well.
