Theoretically, the surface has to be black and rough for best heat dissipation.
I don't think any type of caliper surface coating will affect it's temperature in any tangible way.

 

Finally had a chance to install them.




anyone want a set of cores? have my stock ones laying around if anyone wants to give this a go

 

Polishing calipers reduces surface area by 50%..and surface area is critical for heat dissipation....

As example;

Intake manifold exteriors are not polished becsuse it would significantly diminish surface area, thus its ability to dissipate heat. Smoothing/polishing internal intake runners surfaces reduce heat dissipation into the intake stream. (A good thing)

Really like the polished look, but not diminished heat dissipation....

 

Looks great!

 

Put some slotted rotors on and it would be

 

Here's a full shot. Planning to do the rears too to match

 

That's dope. I like it
I need to re-do mine, instead of the red paint stuff I got from NAPA. Need a professional to do it.

 

Anyone want to have a go? I have an extra set of calipers I can get polished for you and sell you. Or you can get them polished yourself.
