Digsy Posted April 20, 2008 Posted April 20, 2008 Anyone wanting to powdercoat should read this thread first... http://www.my350z.com/forum/showthread.php?t=353258 I'm not suggesting that all powdercoated wheels will crack but you should be aware that there may be a risk which compromises your safety.

GIXXERUK Posted April 20, 2008 Posted April 20, 2008 its a cheap way of lowering the car - fast ! something similar to this was posted before about painting wheels iirc 1 Quote
Chris`I Posted April 20, 2008 Posted April 20, 2008 I've heard this many times and mostly its been dismissed as an urban myth. I've heard if done properly it wont weaken the rims at all, but if done incorrectly then it can have this effect. Quote

M13KYF Posted April 20, 2008 Posted April 20, 2008 nasty, wouldn't of liked to see what happened if the car was oving Quote
Trev-the-Rev Posted April 20, 2008 Posted April 20, 2008 Considering the chassis and suspension components on my race car are powder coated, I'm sure it's a myth Quote
AndySpak Posted April 20, 2008 Posted April 20, 2008 Has anyone heard of this happening on any other standard issue rims or just the GT4 equivalent? (thats what they are on the pic aren't they?) Quote
Digsy Posted May 20, 2008 Author Posted May 20, 2008 Just to follow this up I spotted the following thread... http://www.my350z.com/forum/showthread.php?t=359904 Seems that there have been some accidents where GT4 alloys which have been chromed have also failed. Now thankfully we don't have the same thing for chrome as our Yankee buddys but I am beginning to wonder about the quality of the GT4 rims. If you have GT4s (and they seem to be coming with the new "special edition" 08 cars) I would steer clear of anything which involves a high heat process such as powdercoating and chroming. Quote
sl114 Posted May 20, 2008 Posted May 20, 2008 That is nasty! You are very lucky indeed! Is there evidence of other wheels doing the same? Powdercoated or not as i have never seen this before! I couldnt help but notice this though...http://my350z.com/forum/member.php?u=78448 - off topic i know! Quote

rawbhp Posted June 19, 2010 Posted June 19, 2010 I wish people wouldn't get so excited by this post. As long as the coating is baked on at the correct temp then it's not an issue. If it was, companies like this www.wheelrefurbishing.co.uk wouldn't exist. Like anything, if it's done correctly, it's not a problem. Quote
Digsy Posted June 19, 2010 Author Posted June 19, 2010 If I had GT4 rims I wouldn't be taking any chances. Quote

ben@RARE RIMS Posted July 22, 2010 Posted July 22, 2010 I just thought I'd add to this Powder coating is fine in and of itself. It's the heat involved. Some places use high levels of heat, and heating an alloy ages it. Generally it makes them stiffer and less flexible. This is bad for wheels as if they cant flex a little under load the will crack at the hardest points, usually where the spokes join to the outer rim. Another example is filing cabinets believe it or not. They get away with a thinner steel by heating and powder coating it, to make it stiff enough and strong enough for purpose, making them nice and cheap Ultimately a lightweight wheel has heat treating in the manufacturing process, and comes out of the factory light and stiff. If you them significantly heat them again for powder coating you effect the previous process, and then you see these wheel failures. We tend to suggest getting wheels painted is the way forwards, as this heating is not required. Interestingly for these reasons on racing / track / drift cars when they get their new forged wheels it says in the manual from the manufacturer they need to be replaced every 2 years, they're a service item, which is why so many are sold from Japan, they are used for this period then replaced. They are then bought by people here, and a significant number of them have cracks that need welding. Quote
Rubber Posted July 22, 2010 Posted July 22, 2010 Just had a look at the my350Z post - gotta love the goolge add for powercoating at the top of the banner!!!! Quote
Airro Posted August 4, 2010 Posted August 4, 2010 If I had GT4 rims I wouldn't be taking any chances. i got my gt4 rims powdercoated after reading this...3 weeks still no cracking will definately let you guys know if anythin happens Quote
jub Posted September 21, 2010 Posted September 21, 2010 Does anyone know of any places around London (North London preferably, so Herts etc) that do a good job at powder coating? If not, wet painting? I've got stock Rays. And this wheel cracking issue, I'm assuming if they're coated at the right temperature then it shouldn't be a problem? Quote
yokomo Posted September 21, 2010 Posted September 21, 2010 Just had my rotas done st wheelrefurbishing.co.uk as posed above . Based in herts and seem to know their stuff ,if you go for some of the more exotic finishes they spray them like my black chrome or the brighter silver finishes so that will be ok for sure. Quote

Ah gotcha, nice one. I'd be going for matte black with a red lip. How long did it take them? Quote
