GT-Level Status: Upgrading the 992 Targa 4 with a Full GT3 Carbon-Ceramic System
The Porsche 911 Targa has always been the gentleman's sports car—a unique blend of iconic open-air style and all-weather performance. For one 992 Targa 4 owner, however, that elegant package deserved the braking performance of its track-focused sibling, the GT3. This case study showcases the ultimate OEM+ transformation: a complete conversion to genuine GT3 calipers, paired with a state-of-the-art STOPFLEX Carbon-Ceramic rotor system.
The Upgrade Plan: A Complete GT Conversion
This wasn't just an enhancement; it was a fundamental change in the car's character. The goal was to install a complete, balanced, motorsport-derived system that delivered on all fronts: power, weight, and aesthetics.
Front Axle: Upgraded to Porsche GT3 6-Piston Calipers with STOPFLEX 410mm (16.1 in) Carbon-Ceramic Discs.
Rear Axle: Upgraded to Porsche GT3 4-Piston Calipers with STOPFLEX 390mm (15.4 in) Carbon-Ceramic Discs.
Brake Pads: A full set of STOPFLEX Performance Pads, formulated for the GT3 calipers and carbon-ceramic rotors.
Why This is the Ultimate Targa Upgrade
This conversion elevates the Targa 4 from a brilliant grand tourer to a true multi-role supercar, capable of carving canyons with the same confidence as a dedicated track machine.
OEM+ Perfection: Using genuine Porsche GT3 calipers ensures factory-level fit, finish, and electronic integration. Pairing them with our advanced carbon-ceramic rotors creates a system that is even lighter and more thermally capable than Porsche's own factory PCCB option.
Aesthetic and Performance Synergy: This upgrade is a win-win. The iconic, larger GT3 calipers provide an immediate, aggressive visual statement, while the full carbon-ceramic rotor system offers a monumental leap in performance.
The Result: A Targa with No Compromises
This Targa 4 now possesses the braking capability to match its powerful engine and sophisticated chassis, transforming the driving experience in every scenario.
Unshakable, Fade-Proof Power. The combination of the GT3's massive calipers and the limitless thermal capacity of our carbon-ceramic rotors gives the Targa braking performance on par with a dedicated track car. This inspires total confidence during high-performance driving, with zero fade, stop after stop.
Sharper, More Dynamic Handling. Even on an all-wheel-drive GT car, the physics of unsprung weight are undeniable. This conversion shaves a massive amount of weight from the most critical area of the car, allowing the suspension to work more efficiently. The Targa now feels more nimble, turns in more eagerly, and delivers an even more connected, classic 911 driving feel.
Style and Refinement. The upgrade also perfects the daily driving experience. The system is completely silent, and the zero-dust nature of the pads keeps the beautiful 20/21-inch wheels pristine, preserving the Targa's elegant, head-turning looks without constant cleaning.

Questions About the Targa GT Conversion
Q: Can the GT3 brake system really be installed on a standard 911 Targa 4?
A: Yes, this is a popular and highly effective OEM+ upgrade. Using genuine GT3 calipers combined with our engineered STOPFLEX rotor kit—which includes the correct rotor hats and mounting hardware—allows for a direct, bolt-on conversion that integrates seamlessly with the car.
Q: Is this upgrade overkill for a car like the Targa that isn't a dedicated track car?
A: Not at all. While it provides track-level capability, the primary benefits for a Targa owner are realized on the street: a massive increase in braking safety and confidence during spirited driving, a noticeable improvement in handling agility from the weight savings, and the virtual elimination of brake dust, which keeps the car looking its best.
