Default hollow twist turbo wheels

hi, will the value of wheel depriecated considerably if it is power coated once or even done it for the second time?

What is the reasonable price for hollow stock turbo wheels now?

thanks

My wheel refinisher has told me that full-temperature powdercoating is not good for the integrity of these wheels, but there is a truncated process that limits the temperature of the 'cooking' that preserves the metal strength.

My initial thought upon reading this was that it's hard to believe that 15 minutes at 400F (pretty standard in powdercoating) would have any significant impact on our wheels, but it raised my curiosity...

I found LOTS of anecdotal and keyboard warrior opinions on the web, but I also found these two technical papers published on the subject. I'll admit I didn't read them in their entirety, but from what I skimmed and reading the conclusions section, it appears that there is NOT any significant risk of degradation from the heats and times commonly used in powdercoating. Pretty sure most automotive wheels are made from 6061 aluminum.

Best price I've seen recently for true hollowspokes in great shape was $600, but they were sold almost instantly... $1,000 is more typical. Worth paying a bit more for local wheels to avoid the shipping and so you can inspect for damage yourself.

It's like an urban legen re: powder coating wheels. Painted ones are still cured in heat.

Forgeline did my wheels and recommended powdercoating the faces. I will trust them considering how many else do.

I haven't seen many good shape wheels for 1000. Bought a clean set for 1200 last week

I've got a good set maybe 8 outta 10 cosmetically with Hankook tires with 75% tread for $1200.

I think a nice silver OE set look better than painted ones, but taste is subjective. Our cars are getting old enough to leave stock and be glad you did later (do what I say, not what I do).

What color car and wheel?

Looking for a set myself, wouldn't consider anything not stock.

Hoping to score a nice set for < $1k, but as mentioned above, those probably don't last on the market, and like the 996TT market itself, it's not the same as it was a couple years ago.

I don't mind making mods to my Porsche's, but I always like to have everything to put them back to 100% stock.

When I purchased my car, it had OEM wheels but a previous owner had powdercoated them black. I picked up a set of excellent condition factory hollow spokes earlier this year for a very decent price. They're sitting in boxes right now, I'm still deciding if I want to keep the black ones on for a while longer but glad be able to go back to the stock look if I choose.

Picture of her from earlier today, up on jack stands for some service and a boost pressure leak test while the weather is crap. So far the only 'leak' I found was the rubber connector that connects the airbox to the turbo inlet pipe. Had a small split in it just under the hose clamp. Probably had zero effect as that portion isn't pressurized but instead just under light vaccum, probably not enough to actually leak air, but ordered a new pipe instead. Next time you take your airboxes off, inspect that rubber part carefully... Mine looked fine on casual inspection, but looking closely and flexing the rubber deterioration was pretty evident. Part number 996-110-621-70 if anyone cares.

I also picked up another set of replacement OEM tail lights as mine had the micro-cracks on them. The replacement set was in perfect condition, but had been tinted dark. Probably going to remove the tint, but put them on just to see how it looked.

Kind of goes with the dark wheels and dark tint, but pretty sure I'lll take them back to stock color (tint removes super easily). Thoughts?

By the way,
what is the cost of a decent power coating job in US?
Is US$150 okay?

150 a wheel sounds about right.

Since you're asking, stock wheels + taillights will look 10,000% better.

Maybe it's my Honda roots, but I've never been a fan of black stockers. It looks like you wanted to change the look of your car, but couldn't afford rims.

I know painted black was a Porsche factory option, though, and to each his own.
