Brakes 911 GT3 Models

The new 911 GT3 also demonstrates top performance when it comes to negative acceleration. Here, we rely on our expertise of many years as well as technologies that have passed the acid test of motorsport.

The new 911 GT3 is equipped as standard with a particularly powerful 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 highly resistant to deformation and enables a more rapid response and release of the brake, even under heavy loads.

The brake discs are 380 mm in diameter, front and rear. Thanks to their two-piece construction with cast iron brake discs and aluminium brake chambers, they save weight and thereby reduce 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.

Porsche Ceramic Composite Brake (PCCB)

Flacht is something like the gateway between the race car and the series production sports car. The optional Porsche Ceramic Composite Brake (PCCB) is the best example. In numerous racing series, including the Porsche Mobil 1 Supercup, it has been proven to withstand the harshest demands of the track.

PCCB dimensions are sized to match the performance potential of the new 911 GT3. That’s why the cross-drilled ceramic brake discs have a diameter of 410 mm at the front and 390 mm at the rear – for even more formidable braking performance.

The use of six-piston aluminium monobloc fixed brake calipers on the front axle and four-piston units at the rear – all finished in yellow – ensures extremely high brake forces which, crucially, are exceptionally consistent.

PCCB enables shorter braking distances in even the toughest road and race conditions. Safety under high-speed braking is also improved thanks to its excellent fade resistance.

The key advantage of PCCB is the extremely low weight of the ceramic brake discs, which are approximately 50 % lighter than standard discs of a similar design and size. As well as enhancing performance and fuel economy, this represents a major reduction in unsprung and rotating masses.

This results in better roadholding and increased comfort, particularly on uneven roads. Plus greater agility and further improved handling.
