Such as THIS!!!!!!!!
Need these to be a little bit darker and different color to fit the car better.

It is not advisable. The Oven temps are within the heat treating range of the aluminum I think.
Though I'm not sure how they do it from the factory. Maybe if there are lower temp powders.
Nice wheels.

I'm not buying that arguement... Schwing is powder coating in a Kitchen oven, so it is likely in
the 400-500 F range. According to the link, for 7075 (just a random choice) the annealing temp of aluminum is 900 F for two hours. That's a 400 F "safety buffer" ... I can't see there being an issue. The aging temp is 250 F for 2 hours, and that actually STRENGTHENS the material... That temp will be reached (surpassed) during powder coating! If you lower the temp after powder coating to 250 F, and then follow the recommended cool-down process outlined at the link, you should acutally have STRONGER wheels after powder coating that you did when you started!
What aluminum alloy are most wheels? If it is 7075, I say "Myth Busted"...<ul><li><a href="http://www.suppliersonline.com/propertypages/7075.asp">http://www.suppliersonline.com/propertypages/7075.asp</a</li></ul>

i have a powdercoat guy that says.......
if you dont have to bake off impurities then your good. because if your coating old rims or whateverno matter how good you clean it it will have oil dirt and other junk on it so they bake it at high temp it burn off anything thats there. he advised me if i wanted to get rims coated to go buy new ones and he would do it. Hes been around for the last 15 years so i guess he knows a little bit.

just do it...don't worry about the softening deal..
they may soften while heating, BUT they'll reform to full hardness right after....
life's too short to worry about chemistry too much

You need heat and time to cure the powders...
Most specify 400 degrees for 15 to 20 minutes..
Even though they'd probably take the temps fine, I still dissasembled my brakes when PC'ing them. Shocks would definitely be out of the question..
