Stoptech 2-Piece Aero Brake Rotors for your F8x M3 M4

[HP Autosport]

The Stoptech Aero Rotors helped our customer survive track sessions without fade, but didn't keep the painted OEM calipers from turning green. His other caliper turned black from the heat.

Is the stock calipers painted with heat resistant paint?

I been meaning to repaint my calipers and I am going to ask for heat resistant Red but since I don't track I don't think it will matter that much to me. I'm just honestly curious

I am sure it is, but still will not stand to the heat reached on the track. For the street you are fine.

Have you thought about anodizing or some sort of a coating?

Well, that will protect the painted surface from contaminants, but not heat from the brakes.

Like you mentioned before as long as you are street driving the car, the painted surface should be fine.

The coating on the calipers and wheels will keep them clean much longer and brake dust is likely to accumulate. Have done it to all of my cars with painted calipers and wheels. No wheel cleaner required, everything just hose right off.

Yeah, I am probably doing it soon lol. I'll see what my detailed friend tells me and I'll go from there. Need to protect my R10Ds

Any update on the results after the application of the coating?

How were the dust seals on those calipers that turned green or black? My track prepared M4 still has blue calipers but the dust seals are entirely destroyed. The seals are being replaced at the dealer now. Even the rear dust seals are damaged. With 285 and 315 Hoosiers, I guess I can expect a lot of heat.

Oh definitely a difference. I can literally blow off the brake dusts from my rims lol. Handy

When the color start the change on the painted calipers the rubber dust seals are basically none existent. There is a reason why racing calipers don't use them. That said, some dust seals last longer than others.

I have been looking for the stoptech slotted option for F8x and can't seem to find any anywhere. I realize this post is 2 years old...but thought I'd check.

Yes, these are available. We sold a set just last month.

They don't make these for the rear? I like slotted rotors way better than drilled, but doesn't it look weird if you have slotted on the front and drilled in the back?

No, nothing for the rear.

It will look weird but these rotors are more for functionality than looks.

The prices of these rotors have come down significantly compared to when they first came out. It's a very good value for a two-piece lightweight rotor upgrade for your F8x M3 M4.

Having a cooler running brake system means longer wear on both your pads and rotors.

Possible to get drilled and slotted rotor?

PM for a set of slotted zinc coated?

It's either drilled or slotted, but not both.
