Moving to Brembos was one of the best things I've ever done. I had Baer light weight calipers which were total garbo. Noisy, can't stop 800hp well and the worst part was mess they made.

I traded someone straight up for the stock Brembos. Just threw it out on FB Marketplace and the next day we met in a parking lot and did the exchange.

The same race compound on a 6 piston will always be better than that same compound on a 1-4 piston.
Why? Unless topic is track only. Honest question.

If you hammer on the breaks and the pad is full send against the rotor wouldn't tire traction be the limiting factor to braking distance? Then wouldn't a 4 piston with aggressive compound still be able to bite enough to stop just as fast (at least a few times before fade kicks in) on the street?

No argument against a big advantage for larger rotor in heat buildup and dissipation, which is critical for any kind of track even light HDPE use.

Happy to be wrong and learn something.

A 6 piston is going to simply bite better and have more clamping force than a 4. Which means that it can make make use of the braking components more efficiently. Larger rotors are going to dissipate heat faster. Yet, if I'm running something like a Carbotech XP10F on my 86 (which I am) and the guy behind me is in a car with OEM pads but 6 piston calipers vs my 1 piston, I am still going to be able to brake later than him and get on throttle sooner than him, because the pad and fluid is that more superior.

Weight of the car of course has a role to play as well as tire compound and suspension geometry/chassis refinement. My point is car for car, compound for compound, a 6 piston vs a 4 is going to have superior braking control.
