Powdercoating Forged wheels..?
So i mentioned powdercoating forged wheels on s2ki (s2000 community) and a few mentioned that it was a bad idea.
I'm looking for some experience here from guys who have powdercoated forged aluminum wheels such as ccws and their results when tracked/abuse with the wheels
One guy mentioned that he spoke to John at ccw and he was not totally against powdercoating, but did mention that it could weaken the wheel.
Another guy mentioned that there were documented failures of CTSV's optional forged wheels after powdercoating...

I've asked this question a number of times myself and never got an answer. I was concerned that since powdercoating involves heating the wheels, I was concerned it may compromise the heat treating process. I suppose it depends on how much heat is used and the cooling process. A metalurgist could give us an answer.

I'm a M.E. and always overthink stuff, thats why I'm bringing up the question. It probably won't be a concern, but I'm just curious...
Powdercoating curing temps are about 390-400deg F. Depending on the type of aluminum used, annealing normally occurs around 650+ deg F.
But I'm not sure on the effect on strength of heating then cooling the aluminum at this temp during the process. Thats why I was asking for real world experience, because sometimes even when something works out on paper, in the real world it reacts differently.

Forged wheels are usually 6061-T6...one look at the table in the link above reveals 400°F for 20 minutes won't do anything to the strength of the wheel. If anything, it would make it stronger but the time spent at 400°F in the oven to "melt" the paint isn't enough to raise the temperature of the aluminum wheel to the aging/precipitation heat treatment temperature.
The "one guy" that spoke to John at CCW is most likely full of BS as well as the others on that forum. Lack of knowledge does not prevent some people from talking/posting...it's like a disease and it manifests itself by BS spewing from the mouth/keyboard.

Bill.... 
I doubt CCW and many many other wheel mfg would powder coat if strength was compromised! Perhaps under EXTREME track conditions but then why would you want powder coat to start with?My guess is a large enough POT HOLE can raise hell with any wheel if hit hard enough.... somethings going to give!
I'm looking forward to receiving mine HOPEFULLY this week! Post some pic of them if anyone is interested....

me? or him? lol
i went with 18x10 and 18x11
gunna use the 275/35/18 kuhmo mx i have sitting here for the front and bf good kdw 295/35/18 for the rear for the time being. then when i go widebody i will get larger tires and possibly spacers depending on how much clearance i have back there (i will want them to sit flush)
