Brembo GT-R as a solution to B8 brake heat

[PsYkHoTiK]

Single apex. Let me explain:

In the approach to turn 1, I bring my car all the way to the left like I want to clip the bridge support. Then the car wanders to track middle at the top of the hill where I am still flat out. A gentle nudge left for turn 1 has me clipping the white paint (rain runoff) of the track entry zone. Then I straighten the car out for the last 1/4 of the downhill and brake at track middle.

I extend the braking zone almost to the white line, get the car to change direction, and at that exact moment throttle steer through the curbing on the left adding judiciously until it lands me in the curbing on the right. Now the car is pointed at turn 3 and I’m full throttle aiming for it.

Got it, so you go wide and deep and don’t even touch the first apex (and instead “late apex” to hit the second set of curbing). I think that’s the school line too.

My approach is the same as yours right up until braking. I get really close to the bridge support (lol great pics from the photographer too) and aim for one of the wooden telephone/electric poles to see me through the crest (I want to say the middle one - it’s more muscle memory from the two days I was there). From there, I track out 2/3rds of the way right, shave off a bit of speed, and then line up the car for the first apex (when the brake markers are done) and brake hard in a straight line and pivot/rotate the car when the front driver side wheel hits the rumbles. Holding the wheel will double apex the corner for me (with appropriate throttle steering). The RS5 seems to complain less when I do it that way (if not, I feel the front inner wheel braking to stabilize the car - something I’m actively trying to avoid - mainly to manage brake temperatures).

Man, I really, really miss that track… I want to go back so bad…

not sure if others saw these, but ecs makes a 2 piece floating wave rotor for the rear and fronts now. Much cheaper than the oem setup. http://www.ecstuning.com/Audi-B8_S4-Quattro-3.0T/Braking/Rotors/ES2681109/

Not for track use. I recall a thread on AZ where they didn’t fare very well to abuse.

Yea the guy with the rs5 vert killed the ecs rotors in 1 day. Stoptech aero rotors would be a very cool option. Pun intended.

Agreed - I toasted my fronts at Daytona and would avoid all brake setups from ECS if you intend to use them on the track.

[justincredible]

I just a few weeks ago helped swap out ECS rotors for OEM rotors after he too toasted them after 1 light part track day. I think ECS is getting cheaper and cheaper blanks to cut costs. But it’s clear they don’t hold up

[drob23]

I don’t really want to shit on them…But yea, not the right tool for the job. I think because the cross drills.

West showed the jhm rotors weren’t great for the track also, probably because they don’t float at all.

But both those rotors would be great for straight line speed at the strip.

Oddly, I think both the Stillen/AP and the JHM rotor were insufficient because of the floating hardware. I understand that’s a good place to save money because no one will pay for it, until they have this problem.

When in doubt, go Brembo. They simply don’t f*** up.

[PsYkHoTiK]

I’m very pleased with my Girodisc 380mm rotors.

They’ve held up very well to my abuse.

[westwest888]

These brembo discs are holding up well as the track season grinds on.

How are the rear wave rotors holding up?

How are the rear wave rotors holding up?

Rear wave rotors are still the best option. They consistently get up to 650 F, same as the fronts. I think the stiff rear spring rate holding them down is what’s enabling them to participate in braking.

[drob23]

One of the stoptech reps on AZ asked the question if people would pay for rear 2-piece aero rotors. I’d be all over that, hopefully while my JHM’s are in good condition.

The stoptech “sport” rotors are essentially the same as the adams, ecs geomet and other random suppliers that buy factory blanks for uber cheap and then press some holes/slots into them. Waste of money for sure.

Good to know this option is out there and holding up, thanks!

Nice, I would definitely be all over 2-piece rear aero’s! I also agree re the stoptech “sports” but got them anyway just to go with my new pads in the rear. They seem to be holding up for now but I haven’t done my suspension yet and would anticipate seeing what West is experiencing when I do (higher temps in the rear). Not sure my rear setup will hold up at that point (stoptech sport rotors and stoptech street performance pads).

I can’t get behind this new ECS/Porsche kit.

My friend just bought that porsche kit for his s5, and is going to run ebc Yellowstuff with take off Pirelli slicks…wouldn’t listen to me when I told him those pads suck for track driving. Will find out in a couple weeks lol

I suppose it will get the job done. But SUV calipers on a car is like using a demolition hammer on a finishing nail. 30-32mm is the correct front rotor width for this platform. 38mm is absurd. Even the RS5 ceramic kit is only 34mm wide.

Speaking from experience, there’s two ways to do this. The cheap way, then you buy Brembo. Or you just start with Brembo or StopTech.

Yellow stuff pads work for me. I like them and they showed very little wear after 17K miles and four track days.
