Carrera GT Parts & Performance Upgrades

Engineered by Carrera GT specialists

Every product we develop comes from hands-on experience with dozens of Carrera GTs. We know what fails, what owners want, and what the car deserves. Our parts solve real problems—not imaginary ones.

• Designed by technicians who work on Carrera GTs daily, not generic aftermarket engineers.
• Reversible by design so the car can return to stock and preserve originality.
• Sold with professional installation in our Stratford facility or to qualified partners worldwide.

Repasi Motorwerks Carrera GT exhaust

The Carrera GT's V10 already sounds incredible. Our exhaust makes it louder without changing its character—more volume, same F1-derived pitch, engineered for real-world use.

• Stainless steel construction with four race mufflers for tone and durability.
• Under 30 lbs total weight—saves nearly 50 lbs versus the factory exhaust system.
• Flex pipe section matches factory design for perfect fitment and longevity.
• Uses all factory mounting points and requires no ECU tuning—completely reversible.
• Delivers a deeper, more present exhaust note that stays subtle at cruise and alive at full song.

Surface Transforms carbon ceramic brake upgrade

Factory Carrera GT rotors cost over $90,000 to replace through Porsche. Our partnership with Surface Transforms provides a smarter, higher-performing solution that protects both value and safety.

• Carbon Fiber Reinforced Ceramic (CFRC) rotors with a continuous 3D fiber matrix.
• Approximately three times the heat conductivity of factory rotors for better thermal control.
• Lower wear rate and oxidation for longer service life and more consistent performance.
• Direct bolt-on fitment with no permanent modifications required.
• Rotors can be refurbished, extending lifespan while original OEM rotors can be preserved in storage.

More products in development

We are continuously developing parts that address Carrera GT ownership challenges—suspension components, cooling solutions, and interior upgrades tuned to how owners actually use their cars.

• Early access for owners who share feedback and real-world data with our team.
• Development roadmap shaped by common issues we see in the workshop and on PPIs.

Professional installation included

Every part we sell can be installed at our Stratford, CT facility by the same technicians who developed it. No third-party guesswork and no warranty confusion.

• Factory-spec removal and refitting procedures performed by CGT-experienced technicians.
• Torque-logged fasteners, before-and-after photos, and clear documentation of all work.
• Validation testing appropriate to the part—road test and sound check for exhaust, bedding procedures for brakes.
• Original parts packaged and returned or stored per your preference.

Worldwide shipping and logistics

If you do not have a local shop you trust, we can ship parts worldwide with proper packaging and insurance or coordinate enclosed transport to Stratford for combined service and installation.

• Detailed installation instructions included for qualified technicians at partner shops.
• Phone and email support available to shops installing our brake and exhaust packages.
• Enclosed transport coordination for owners who prefer us to install and validate upgrades in-house.

Frequently Asked Questions

Are these parts reversible?

Yes. All of our Carrera GT parts use factory mounting points and require no permanent modifications, so your car can return to completely stock configuration at any time.

Will these upgrades affect my car's value?

Reversible, well-documented upgrades from a recognized CGT specialist typically have neutral or positive effects on value. We provide torque logs, photos, and full documentation with every installation.

Can I buy parts without installation?

Yes. We ship worldwide to qualified installers and include detailed instructions. For complex items like the brake upgrade, our team is available to support your technician during installation.

What is the lead time for the exhaust system?

Our exhaust is custom fabricated per order. Typical lead time is 4–6 weeks from order confirmation to shipment or installation date.

Are the Surface Transforms brakes in stock?

We maintain inventory for immediate availability but recommend contacting us to confirm current stock and schedule installation.

Do you develop parts for other Porsche models?

Our proprietary parts program currently focuses on the Carrera GT, but we also install curated aftermarket components for GT3, GT3 RS, and other platforms through our Performance & Setup service.

How do I know if my rotors need replacement?

During service visits and PPIs we measure rotor thickness and inspect condition. If replacement is approaching, we discuss timelines and options, including Surface Transforms upgrades and preservation of your original rotors.
