Burning Brakes

Love how casually the 911 Turbo hits 200...... While it took third in the braking test, the other two were running R compound tires which demonstrates how powerful the tires really are. (assuming the 911 Turbo S and GT3RS braking systems are relatively similar)

correct - braking distance is about deceleration g's - which is about maximum tire grip levels - which comes down to tires and their maximum grip levels for the conditions
braking distance is also affected by ABS modulation which "normalizes" the results because the tires/wheels are not allowed to lock up
braking performance and repeatability is about the rotor material and pad material - i.e. how much stamina and thermal capacity the brakes have to perform the maximum-g deceleration - once brakes are thermallly saturated you'll get brake fade which will elongate stopping distances and may lead to actual brake failure
_ALL_ porsche brakes (steel, PSCB, and PCCB's) are subjected to the same "torture" test document in this article about the Taycan
https://www.roadandtrack.com/new-car...n-huge-brakes/
PCCB's are in fact better brakes - but not in the way most people would guess/assume - they are superior in terms of thermal endurance but stopping distance/time is 99.9% governed by tire grip levels for the current conditions - which have nothing to do with the rotor compound…
nothing stops like a fresh pair of slicks on 911 Cupcar on a set of steel brakes - the tire grip levels you have with slicks is so so so good - you can basicaly stop the damm thing on a dime - it almost goes backwards when you touch the brake pedal.

A spokesperson told me that every Porsche is required to pass a braking torture test: 25 stops in a row, from 80 percent of a car's top speed down to 90 km/h (56 mph), with every fifth stop involving full ABS. For a car to pass, it has to generate between 0.8 and 0.9 g of deceleration every time.

there are tire options for 911's that can provide more grip, but less range of driving conditions, but on track in the right temps the grip levels are simply stunning.

Can someone explain how the stang out braked the Porsches??
