Brembo Race System?
 

Anyone have details on these?

I've worked with these race calipers before on true racing applications.

They seem, from the two price point I've found, to be considerably cheaper than the GT-R. Why?

See bottom of this list:

Here is an image of what the assembly looks like.

I think it kind of weird that according to Brembo their package called "race" isn't good for racing.

That is some what interesting.

After digging a bit it seems these are technically branded as 'Club Racing' upgrades. For instance, these may not then be up to par for PWC, CTSCC or other professional level racing. I can't find the caliper part numbers for any of the kits for any cars, but they sure look like ones offered in the Brembo Motorsports catalogue... Perhaps they aren't from there though.

That and I'm not sure that this car really needs 355mm rotors for a car of this weight.

14-15" front rotors are pretty standard in GT4/GS and GT3/GTD and all of those cars weigh less than a reasonably weight reduced FT86 - although in near stock config a BRZ would be in a TC class. Yes I know, GT3 cars actually have downforce (over 1200 lb @ 150 mph), generally much more power, with much better tires than are readily available.

I think it's more than feasible to run these sorts of brakes on a fun weekend car that you do track hard that does have sizable upgrades (boost, good springs/shocks, R1 tires, etc). I'm here because that may be what I'm interested in doing...

There just doesn't seem to be much publicly available information on these Club Racing upgrades. Then also what's the point of the GT-R kits if they offer less for the track but cost 2-3x more than a regular GT kit and these Club Sports? All of the above offer 14" rotors with 4 or 6 pot calipers it seems.

What do you want to know? I am 100% sure we are the only vendor here with firsthand experience with the Brembo systems for the FRS.

355x32 is what was determined to be the equilibrium point for this car with stock power in a race.

Short hot lapping sessions will not be as hard on the brakes as a race, and street/canyoning (short of something like Pike's Peak) will not be as hard on the brakes either.

As a data point, the AP Racing Endurance kit is *not* enough braking capacity for me to run a 20 lap spring race with street tires on a stock car... How many people here are actually racing?

For starters the Brembo p/n for the calipers. Thx

Ah crap. Thanks for deflating my ego even more :(

Which ones?

Before deciding how you feel about it, don't forget to ask why.

I was only 1/2 serious. That's :( divided by :). I know that some tracks that the CSG guys visit are much faster than my local track. The Sprint kit is more than sufficient for the tracks I visit. BUT even so reading posts like that makes me aware of my own ability, or more specifically, lack there of.
*Goes and looks at some track day results to bolster my ego where I whipped some of the more powerful car's asses*

The left and right calipers that are included in the BRZ/FRS Club Racing kit. :D

I'm actually working on a functional rocket bunny kit. unfortunately I went with the AP Sprint bbk kit

Those words are mutually exclusive...

Element has a functional wide body car.

Widebody =/= rocket bunny. Are you doing rocket bunny or Element's setup?

What kind of pads were you running? The AP Racing "endurance" kit is a lot of brake for a 2700lb car. I've seen bigger/faster cars function with less on a track...the caveat is they were using full race compound pads.

Agreed.

Who is Element and what does that have to do with Brembo Race System or Club Racing brake upgrades?

It's a rocket bunny car with a similar setup to element's car. Built block, sparco EVO seats, gtx 2867 turbo, Cusco diff, rear seat delete, Tarmac 2 coilovers, AP sprint BBK kit, apr wing, custom designed aero, 5 point harness, harness bar, and some small susoension components.

We're using race compounds.

Small gains in lap times result in exponential increases in wear and heat.

Well, Race Technologies got a call!

p/n left xb1.e7.23 and right xb1.e7.24.

Out of the Brembo catalog these have an msrp of $850 each. These are racing, or more correctly TRACK DAY, calipers as the cost savings are in the production of 2-piece castings vs 1-piece forges or billets and Fe inserts instead of Ti. For reference, the cheaper of the two F3 4 piston calipers msrp at around $950. The biggest downside is the lack of any bridging which will reduce the calipers torsional stiffness vs with a bridge. The question is it enough to have any performance impact; The AP kits by Essex only have a single bar bridge.

Info is top of pg 24 in this doc: http://www.brembo.com/it/Auto/Racing...MBO_RACING.pdf

That's a fun catalog to look through. :)

The lack of a bridge is concerning but I don't know enough to say if it will be felt. Maybe the caliper is just that strong.

With the piston sizes listed in the catalog and 355mm discs, you'll have a pretty decent frontward shift in brake bias. I'd go smaller than 355 if you could, or add a rear kit. But assuming you're running hoosiers, it may be an acceptable tradeoff to get the fade resistance you need.

It's only a concern if it does have significant deflection. I have history with the old 4 and 6 piston NASCAR intermediate Brembo calipers that had no bridge...The only problem we ever had was a clip failure one time where the pads flew out on a pit stop - same issue could happen with these Club Racing kits. I bet Hayworth might have some data on the old NASCAR intermediate calipers vs the new bridged versions. I have seen test data on their RC calipers, so it could be out there... Might not be 1:1 comparison with the Club Racing calipers but could be a rough way to gauge the importance.

Rear upgrade easily solves the balance problem. The two piston rears available in the Brembo catalog have the same mounting offsets as the production 2 pistons that are on the WRX Stis (28 mm) - choose your bore (36, 38, 40, and 42 mm). They are less than $300 each. And rotors are cheap! BTW, who builds a 'race car' without a bias adjuster? :D

EDIT: the rears are 500 each...

Funny, I'm having lunch with the friction engineer tomorrow... :thumbsup:

Cool, wasn't sure how serious your build will be. :)

Seems like you've got a good background already with brakes and specifically brembo. Please keep us posted on what you end up with!

Childcare costs over 3 grand a month (three kidlets under 3) which bites into (fxvking devours) fun money. I need to pickup a second job...

Hoping to start something and the FT86 plateform looks right! We'll see...
