In socal, check with powdercoater.com, they do good work. Not to be confused with me, thepowdercoater dot com

Phimosis

Unfortunately, the color that my pinstriper mixed up was not to my liking, so he ordered a couple more colors. They should come in today, but then he has to mix it, paint the wheels, overnight to dry, then back to the powdercoaters for the clear coat. I'll shoot some photos before they go back on the car, but I'm doing 15 mm spacers and Bridgestone RE11's with 275 front, 305 rear and it will be another day or two before it's all assembled.

I'll start a new thread next week and post all the pictures from start to finish. For now, I'm not telling the details so there is an element of surprise. I'm sure some will love it and some will hate it....

You are right sir, heating forged wheels to that high a temp weakens them significantly...

Phimosis

Agreed. Make sure not to buy any powder coated wheels as they will be significantly weaker than painted ones or ones that are bare aluminum. I haven't seen any like that, but I'm sure they are around.

>>>Volk Racing Wheel TE37 Spec. List :
>>>Material is 6061 aircraft grade aluminum. This material is hot forged. 1st >>>forging process is done with pressure of 5,000 kilograms per square >>>centimeter. 2nd forging process is a slow process
>>>with 3,500 kilograms per square centimeter. The lip is also forged to 3,500>>> kilograms per square centimeter. This allows the wheel to have less >>>material than other wheels, but have more strength and durability. The >>>excess material is machined off (to tolerance of 1/100 of a millimeter). >>>Powder coating and clear coating is done by a special proprietary process >>>to ensure long lasting quality and durability


Ok. Let me edit this for those that don't see my wry wit. Almost every wheel on the market is powdercoated. If it's not chrome or some type of metal coating, it's a baked on plastic finish. Paint just won't hold up to the abuse of even mounting the tires at the factory. There are some processes that bake plastic sheets onto the wheel, so it's technically not powder coating, but it's still a baked on plastic. The wheels have to be forged first, or it would melt the plastic finish off. So the Volk wheels above are powdercoated and made by Rays. I don't have the exact info on the stock Rays wheels, but based on the durability of the finish and how hard it was to remove, the stock wheels are powder coated, too. I'm not sure where this idea came from that powder coating wheels will weaken them, but it doesn't make sense from a technical standpoint. how hot do the wheels on your car get when racing on a 100 degree day? Air is 100 degrees, pavement is 200 degrees, disk brakes are glowing hot, well over 1500 degrees, transmitting lots of heat to the wheels. If your wheels hit 200 degrees every day doesnt that not effect the strength of the wheel, but heating it to 400 degrees for an hour does?

I think the weakness issue is overstated. If I break or bend a wheel, I will surely let you guys know.

Here is powdercoat curing info:
A convection oven uses a heat source, most commonly a gas burner,
and a fan to heat the interior of an insulated enclosure. Different powder
materials require different cure temperatures, commonly in a range
between 350 °F and 400 °F (177 - 204 °C). The part is heated by the
hot air in the oven and it in turn conducts heat into the coating.
The coating must be held at temperature for a predetermined length of
time to reach full cure. So the cure cycle is so many minutes at so
many degrees of temperature. The time it takes to bring the metal up
to temperature must be added to the cure time requirement to determine the full cycle time in the oven. Convection cure time may be as short as 10 minutes or as long as 30
minutes, depending on the mass of the substrate and the cure requirements of the powder.

Mike

what he said!

Many OEMs and aftermarket mfgrs powdercoat from the factory. I've seen a few wheels fail at the track, and none of them were powdercoated. Its an old wive's tale.

Me as well - looking sick man

phelan

Only reason I'm holding back on powdercoating my wheels with a gunmetal-esque color is that it'd make my door handles look ridiculous.

CBRich

They already do. Just get it done.

racerxj17

that high? were talking less than 400 degrees here. i wouldnt doubt the inner wheel gets high 200 very easy from the brake heat dissipation every time you beat it up on a track. i would not worry....

im thinking about powdercoating it to gold or bronze. white with gold or bronze is the best combo imo. anyone got photoshop skills to show gold powdered on white?

Minicobra1
