I have seen cases where people want to powder coat their cast OEM or aftermarket wheels. Also I have seen many of the same wheels being sold in the marketplace after they are powder coated. I have no goal to ruin the business for any members here but this is a serious issue.
Cast wheels are not strong enough to withstand the extreme heat of powder coating. There is a good chance that the wheel will develop a crack in the weak spots (spokes usually) and eventually break. If you are buying any wheels that were powder coated outside the factory double check to make sure they are not Cast.

 

I think you have to watch out for the temps the powder coat was done at.

 

Lol what are you basing this on?

Cast wheels are made at 1250F, most powder coating cure cycles are around 400-500F

I know multiple guys who work in metal plating and powder coating and they laugh at this topic every time it comes up.

 

+1. i had some motorcycle parts powdered a few years back and i remember reading posts like these so i asked my powder guy and he laughed.

OEM Rays are forged

 

i love that no matter how many times people pc cast wheels and crack them, there are always people who are still like, "eff that, i heard it's fine to do"

 

As stated earlier,

When I had my teg, I took my team dynamics wheels to a shop to get it powder coated and they said they can do it with no problem. Those wheels went over several pot holes and they never cracked. The only bad that happened. was a blowout after hitting a pothole. But the rims held fine and the lip only had a little nick on it. Wheels were still straight after that incident. (no wobbles) or bend wheels.

So when in doubt, ask the professionals. They're not going to do something that will "crack" your wheels for your safety and their liability .

 

It not I "heard" I have first hand experience. Rob at armor powdercoating coats at least 1 set of wheels a week, not once has he ever had a wheel come back cracked.

Look at the Z that had the wheels completely snap from all 5 spokes while driving, those were OEM wheels 100% stock. Powdercoating doesn't effect the durability of wheels.

I've had metal pieces of hoists and chain falls powdercoated that hold up to 4-5 tonnes, do I trust those? 100% When your wheels start taking impacts of 4 tonnes you have more to worry about than cracks.

 

I think Nissan recalled or had a class action suit going regarding this

 

my OEM cast were PC'd twice - back-to-back well less than a year after I purchased the car... I ran them for over 2 years with zero problems.

It very well may have to do with the process... A Cast wheel will out-gas when baked in the over... a good powder coated will cycle it first to allow for out-gassing (if you don't do this prior to PC there will be blotches in the finish from out-gassing)...

So maybe if the process isn't correct - or as stated earlier, the temps aren't right - you could have problems... hell, there are people that powder coat certain parts at home with their own kits (no thanks).

Take it to a reliable powder coated and you will be fine.

BTW - The sun causes cancer stay out of the sun.

 

And my Ray's are PC'ed

 

Question to Mike. What oem non-forged G35 wheels are made by Rays?

I'll take that as you don't know. (Others have asked this specific question also)

jeff notes that the kindness to SPECIFICALLY answer a question is clearly not reciprocating in nature.
