The all encompassing brake setup for track use thread.

[SBR70.3]

Let's talk about one of the most important consumable part when tracking your car. Brakes.


I am curious as to what you use. If you could, please indicate what you have.

Car (year, make, model):
Calipers:
Rotors:
Deflectors:
Fluid:
Pad (F/R)
Shims:

Likes/dislikes about your setup and what you are going to change:

I will start.

Car (year, make, model): 2021 Mach 1
Calipers: Stock
Rotors: Steeda 2 piece
Deflectors: Vorshlag (sp?)
Fluid: SRF
Pad (F/R): G-Loc R16/12
Shims: yes, titanium

Likes/dislikes about your setup and what you are going to change: Brakes get HOT and I am burning through the G-Locs in 2 weekends.

I had the R12 rear pads deform significantly on one track day and will be going back to R10's. Ken at KNS brakes said it is too much pad for the rear caliper on these cars. I'll post pics of this when I get the chance.

Has anyone tried the Girodisc GP35 pads? I am going to give them a try.

Car (year, make, model): 2021 Mach 1 HP
Calipers: Stock, 6-piston front, single sliding rear
Rotors: PFC V3 Front, Repro V3 by Pro-System, Mooresville, NC rear
Deflectors: AJ Hartman, front deflectors
Fluid: PFC 665
Pad (F/R) Cobalt Friction, XR-2 Front, XR-3 Rear
Shims: None

I've run this system on another track car and have been running this system on my Mach 1 since basically new. Mustang is a couple hundred pounds heavier than prior vehicle. It's a relatively "expensive" system but I got 5 years and around 25 track days out of the front and rear rotors. This system will generate 1.5g maximum brake force with good track tires (by VBox). Have never experienced fade and braking performance is super consistent. PFC rotors getting increasingly difficult to locate but other suitable rotors are available. Would also recommend Pagid pads (when on sale as. they are getting very expensive) and used to run PFC pads but they've changed their labeling/compounds for track pads and haven't tried any of their new compounds but they used to be pretty good too.

Car (year, make, model): 2019 GT PP1 A10, GT350 suspension, DIY coolers added
Calipers: GT350 front & rear
Rotors: Ford OEM 2-piece, plain (not drilled)
Deflectors: Bamberg, of course!
Fluid: ATE 200, last long time, no issues
Pad (F/R): Ford OEM GT350 take-off's.
Shims: OPM Ti, only for use when pad thickness = ~half. Got them new and cheap from @dstanky .

I like the OEM pads with Cup2 tires because they are easy to modulate. They still brake hard enough to feel ABS onset.
I have measured rear rotor temps as high as 600F! Primary reason to go to GT350 brakes was the superior rear brake. No flex, good braking, rubber survives the heat, and they are MUCH easier to service
