How much are you willing to spend for a different look for your car?

If you do decide to get a set of Rota's, you'll probably have to spend about 5 or 6 hundred bucks to get them to you with tires (don't quote me on the amount, I'm just shooting in the dark). You'll enjoy the benefit of having a different look for you car as well as having another set of wheels to use in case you need it or sell them to offset the cost of the Rota's.

If you powdercoat the GSR's, you'd have to spend on the tire removal, the powdercoat, then the cost to mount and balance of the tires again. Plus you'd need another set to put on the car while your GSR wheels are at the shop. I don't know how much that'll cost you, but it might be near the cost of new wheels and tires.

For my personal taste, I'd go for either the C10's or the Torque's
