Opinion on Big Brake Kits & Tracking

The standard pad the ST kits come with are wide annalus. The street pads they ship with covers the entire swept area.

The track pads however are narrow. Pretty much every performance pad maker uses the narrow annulus shape. It could be because the pad is an ancient AP shape who knows.

I think it's just the way the f80 kits were put together. My E92's ST60 kit with the narrow annulus Track pads use the full surface.

It happens. The more advanced driver you are/become along with the type of tracks you run at all will determine the amount of time it takes to discolor the calipers.

BBK's will help pull heat away from the calipers but even using dedicated brake cooling backing plates your going to eventually destroy the paint.

I've run on 2 different BBK kits along with 2 sets of OEM Brembo setups. All on other platforms) They all faded and turned grayish....

Your best bet is black...it will hide the fading longer than any other color but it will also go eventually.

Deal with it.....

What about anodized finishes? Same issue?

I think the AP/Essex anodized finish is supposed to prevent this from happening.

In terms of paint, I've heard that red is a good option, but black is the safest. I've seen tons of red Porsche calipers stand up to heavy track duty, I wonder if they spec a different paint than the regular red brembos?

I've attached some pictures of my calipers after last track season. To each their own, but I'm a bit too OCD to deal with the eyesore.

Thanks for your post!

Did a little comparisons on the pads.

The Stoptech ST60 AP5 track pad shape is same for AP CP5060 wich has a 50.5mm swept area.

But there's an AP pad shape AP19 that looks to be the same shape but with a 53.9mm swept area.

I'm going to give the AP19 a try.

I was going to ask you what radial depth the ST wide annulus street vs. race pads have but you beat me to it. The 54 mm radial depth is the way to go. I ran into the exact same problem on the Stillen/AP brake kit I had on my e46 M3 - kit came with 51 mm but 54 mm was required to use all of the available rotor surface.

Anyone know if it's possible to use stoptech rotor rings with Brembo GT kit?

Then I'd do a set of rims and good track tires I also run Apex 18" and Nittos.

Noticed your running the APR wing and front splitter...looks great, but did it make any difference to traction/lap times or slow you down on the straight?

It would be nice to still daily the brembo's then swap the type 3 rotors and RE10 pads for track use. It doesn't make sense to daily that stuff, since it will wear out quickly from street use.

Otherwise, it makes more sense for me to designate the brembo's for track use only, and use the stock brakes on street (not spend $5k+ on rotors and pads just to street them.) does that make sense?

Stay clear of Carbotech brake pads, they're garbage. BBK rotors are pricey and they'll eat your rotors alive. Spend a little more to get quality ones. Not making that mistake twice. I like the Endless ME20. Moreover, I also hear good things about the Brembo RE10.

Yeah I also heard good stuff about the RE10's. That's what I'll use when I track them

We’re actually talking about CT street pads. I’ve used CT race and street pads (currently using 1521 compound on my M4 with Essex/AP kit and e92 M3 with PFC kit) for 20 years. They’re certainly not “garbage” but everyone has their own opinion; however, I do use PFC race pads on the track.

Why not use the same rotors and just switch between track and street pads?

I could, I was reading up on the type 3 rotors though, the aggressive face wears faster on the street than normal slotted. So ideally, they are best suited for track only to take full advantage of the aggressive face.

Running them on the street with street pads will be much cheaper than buying a second set of new slotted rotor rings + hats and street pads for street use Save your money for new/spare type 3 rotor rings and track pads.

More pads to fit the wide annulus ST front rotors:

I'm planning to use them for street not for track. For track I already have ferodo uno and PFC. Did you have experience with their street oriented pads?

Carbotech supposedly have an issue of mixing non CT compounds on the same rotor. So if you plan to use a CT street pad you have to use a CT track pad and vice versa.

On my e46 M3 track car I had used CT race, PFC 01 race, CT race (finished off an old set) and then PFC 05 race pads all on the same set of rotors. I didn't have any issues mixing CT and PFC compounds on the same rotor.

PFC race compounds will easily clean off the CT 1521 street compound.
