Can't find anyone that's done the f sport orange like on the rcf and gsf calipers I want to duplicate that as close as I can onto my 350 any advice??

I've seen a RC200t with the Lexus (not F) orange calipers on dealer lots. It was an added option of roughly $500..

Should look into it, and see if that caliper would fit in the IS.

I can say for sure that someone here has done it...hell if I can remember which member.
They did post a pic.
Try searching for other threads about the orange calipers...I believe that's where the pic is.

i just bought the G2 caliper kit in "grabber orange" and bought black lexus stickers to go along, it's the closest in color to resemblance for a cheap price

I'm gonna need some references. I don't think paint on calipers has any effect on brake performance. Hight temps only effect the rotors, the calipers just hold and apply brake pads. That's why theres heat veins on rotors, and no sort of cooling system for calipers.

Haha you're right, very hypocritical of me.
I can't seem to find any arguments via the Google machine saying painting calipers (with specific colors, let alone paint in general) would reduce brake performance. Though I do believe it would reduce heat dissapation, at a such a small scale it wouldn't matter. Brake fade also would be more of a problem during track use, and by then I would be going to a BBK for that.

Sasnuke

I propose that brake fade is caused by heat generation, but the fade is not caused by the heat generated in the caliper, but rather the heat generated between the pad and rotors and transferred to the brake fluid.
Increasing the temperature range of the pads and brake fluid will help to alleviate the fade. i.e. going to DOT 4 fluid and a street/track pad that has a higher operating range.
The down side is that in order for those new components to perform their best, they do need to hit the higher operating temperatures...which we likely won't reach in everyday driving.

If caliper paint affected the heat generation in the caliper, it would be marginal at best.

dchar

Some people have measured the temperature of the calipers after a long drive and noted that it remains fairly cool. So painting them has no effect for brake performance.

To OP, look at VHT burnt copper color. A few have done that color on their GS and it looks great.

I'm prepared to be proven wrong, you don't have to be so condescending. I'm just asking you show me the studies or articles that say colors contribute to brake fade enough to consider black as the only option. Maybe if racing is primary and you need every bit of help, I could see it mattering. Street use I think it has very little impact and any color is good to go. I know you're asking me to show me my references but I'm just Joe blow with some logic, and you're the "engineer" that could easily throw some references to teach us something.

TimboIS

Sorry, not buying the argument. You must be a Takata engineer. LOL.

Like the others said, references.

Sasnuke

Maybe the question should be asked as to what the insulation value of paint is? and it would depend on what paint is used.
I can't imagine paint has any or much insulation factor. And for a street car with street brakes...um yeah.

And with all do respect, don't throw the engineering thing around...I've worked with a gaggle of engineers before, and if you have to tell someone you're an engineer, you're not a very good one...just sayin'.
I'm sure there must be some documented proof out there about the caliper/paint/heat situation. Or maybe no one has bothered. I'd like to see something on paper.

Sasnuke

You do realize that includes your rebuttals as well?

TimboIS

Well, since you brought up the claim initially, the burden of proof lies with you.

In the rest of our defense "you can't prove a negative".

Sasnuke

LOL...pretty much! That's what happens when engineers get involved.
