At the limit, you need one thing above all: reserves. Not only for power, but for safety, too. This is possible only with a race-proven technology on which the driver can depend at all times. Only this can free up extra room for manoeuvre, especially in the red zone.
The new 911 GT3 is therefore equipped with a particularly powerful yet lightweight brake system with a specifically matched brake booster. The red six-piston aluminium brake calipers on the front axle and the four-piston equivalents at the rear are designed as monobloc units. This makes them tougher and enables a more rapid response and release of the brake, even under heavy loads.
That’s not all. The brake dimensions on the new 911 GT3 have been enlarged to cope with the increase in engine power. The brake discs are 380 mm in diameter not only at the front but now also at the rear. Thanks to their two-piece construction with cast iron brake discs and aluminium brake chambers, they reduce weight and thus the unsprung and rotating masses. The brake discs are cross-drilled and internally vented for powerful braking even in adverse weather conditions. Or when pitted against the challenges of motorsport.
