Powder Coated Calipers

[MiamieNeSeX]

What would you pay to have calipers powder coated and rebuilt?

miamieNeSeX,

Those are the nicest looking Calipers I have seen to date, just beautiful. I have thought about painting mine for years, but did not since I was not too happy with teh "texture" of the caliper after just a painting. Yours have that smooth texture like Brembo's!! Love it.

Please let us know where to send them for that kind of work.

Sorry, but I really have no good feel what it would/should cost!!

Is any color available?

[MiamieNeSeX]

Thanks, I beleive he can do them in black, silver, white ,yellow and red

It would be ideal if they were available on a core exchange basis. This way the car wouldn't have to be off the road during the time it takes to perform the powerdercoating.

I'd like silver with black letters please!

BTW what kind of rotors are those? Will they fit under OEM wheels?

It would be but that would increase the cost I am sure, it should take about a week turn around including the shipping time

 

[Biaggi]

So how much did it cost?

Unless there is a new formulation on the market, powder coatings are not heat resistant. This may be ok for street driving, but for track driving.....

 

[MiamieNeSeX]

I had the paint on the calipers that Dali sells for 1 year before I noticed any chipping or fade, I am sure that the powder coating system is a bit better than the brush on. Also tires last longer on the road than they do on the track

 

[Yellow Rose]

Exactly - powder coating is not paint.

The *paint* that Dali sells is heat resistant.

From my friends in low places, powdercoating is *not* heat resistant to extreme temparatures. At reasonable temperatures, powdercaoting is more durable than paint. But stop for a sec and ask, "Just what is powder coating?" In native form, it is powdered plastic, the consistency of flour or baking soda. The plastic powder is sprayed onto a heated object to be coated, and with that heat the powder fuses together to be a continuous film coating. Now, ask another question, "What happens to plastic when it is exposed to extreme temperature?"

BTW what kind of rotors are those? Will they fit under OEM wheels?

If the rotors fit under OEM calipers, then by default, they will fit under OEM wheels.

Question then how hot do calipers get under hard track braking conditions?

 

[cpmoran]

Those are great looking. I hope they last. How did you like the dali paint?

Depends on your driving style and the track. A couple of years ago, a group of us NSXers at a local track event compared brake temperatures with a laser pyrometer. The hottest was a supercharged NSX with stock brakes. (Personally speaking I don't understand why someone will modify their engine to add +100 HP but ignore the brakes.

Kinda dumb.) His brake temperatures was over 400°F. Industrial plastic coatings typically melt at 250-300°F. Like I said in my first post under this thread - driving "mildly" on the street shouldn't harm the plastic coating. However, if you track your NSX........

Where did you measure the 400 deg? Disc, sure but caliper?

I don't recall, it was two years ago. Intuitively, if that temperature was the rotor, the caliper is cooler. How much cooler? Depends on how thick the pads are.

But something to think about. I boiled the brake fluid once at a track event, when I still had OEM brakes. If it was hot enough to do that, then it is hot enough to discolor powdercoating.

I know this has been discussed prior, but I think its better just to paint your calipers yourself. I painted mine red (and highlighted the NSX letters in white and they look today, 2 years later, every bit as good as those photos of the powder coated calipers. While it took a Sunday to complete the task, I didnot even disconnect the brake lines....merely covered the wheel well in vapor barrior and rested the caliper (less the pads)on top of the rotor. The product I used came from a local performance shop...in a spray can (cost $12.00 CDN), called VHT Brake Caliper,Drum & Rotor (its rated at 900 degrees F) in SP-731 Racing red (although they have all colours) and is made by PJH Brands, out of Scottsdale Arizona. The letters, I merely painted by hand using a auto touchup laquer paint tube. The red had to be re-sprayed 10-15 times and some spots had to be touched up by hand until you achieved a perfect finish.

i know people that powdercoat their valve(cam) covers red ala 97+ with satisfactory results. do rotors sustain much higher temps?

Cam covers generally run at engine oil temperature or about 200 degrees F.

Powdercoating is done at approximately 450 degrees, which is lower than brake temps in road racing. Look at road racing Corvette Z06s with their stock red powdercoated calipers, every one of them cooks the coating off. The VHT paint is ratod to 900 degrees, a far better choice for calipers.

Brake rotors see temps above 1100 degrees in road racing, calipers see over 500 degrees, probably over 600 degrees. That's why brake fluid rated at 580 degrees dry boiling still gets boiled on the track even with fresh fluid.

I do powdercoating here, and I also have a set of NSX Calipers that I'm about to coat in red. If anyone is interested, i'll sell them for $400.00 shipping included, with exchange. I'll even pay the shipping on your old ones.
