Verdict on AMG GTR Breaks for track?
Does AMG GTR need a brake upgrade for track? If so what's the most optimal proven setup? Tikt? Renntech or AMG PRO cooling parts?
Currently have 19 GT3 RS WP and trading in my 2015 GT3 for an AMG GTR steel brakes and would love to take GTR to a track, but I am bit worried about the brakes after reading so many negative comments. Thoughts?

For those tracking the car with CCMs, replace the brake fluid with something really ‘sturdy’ such as Castrol SRF; Endless 650, etc. and install the Tikt ducts both front and rear; (especially important on the rear if you run with ESC ‘On’ or in ‘Sport’). Lastly, whilst you can use the OEM pads with the above as they work well, the Pagid RSC1 pads front/rear are a worthy upgrade.

I hear ya, but I thought of it this way... This is their first real designed for track car and all it needed was some brake cooling ducts.... not bad for a first outing
1) Front break cooling (MUST HAVE) -- rears optional??
2) Upgraded High temp brake fluid (MUST HAVE) (Castrol SRF or simialr)
3) Track brake pads (MUST HAVE) (Cobalt Friction XR1 or similar)
4) Stainless steel brake lines (optional)

Further, I’m not really sure that SS BRAKE lines add much if anything, and if installed poorly, could cause a major issue.

I may well be wrong on this but TC generally does not rely on differential rear wheel braking, (and hence causing increased brake pad/rotor wear), rather it employs the ECU cutting power to limit wheel spin. Rather it is the use of ESC that can severely rapidly wear rear (and front brakes at times) brakes due to it using rear wheel braking in order to attempt to stabilize the car.
Hope I haven’t gotten this wrong.
Regardless the rear brakes are poorly ventilated and should be cooled better, hence my suggestion to get both front and rear brake ducts installed.
