What Comes with these Manthey Performance Packages?

Braking

Each Manthey package improves braking performance through cooling enhancements and system optimization. Steel brake line upgrades and advanced airflow design ensure your Porsche stays consistent and reliable under the most demanding conditions, giving you the confidence to brake later and harder when it matters most.

Aerodynamics

Downforce is a critical component in high-performance driving, and Manthey kits deliver aerodynamic upgrades that enhance grip and stability. From track-focused wings to air channeling devices, these packages are engineered to provide greater control during high-speed cornering and braking.

Lightweight Construction

Each Manthey kit incorporates lightweight materials like carbon fiber and aluminum to reduce mass where it counts. Less unsprung weight leads to improved suspension response and agility, helping your Porsche feel more planted and responsive without compromising rigidity or safety.

Tires and Wheel Covers

While the actual tires may remain unchanged, Manthey kits include specialized wheel coverings that reduce turbulence around the wheels, contributing to better airflow and improved efficiency. This seemingly small enhancement plays a big role in reducing drag and boosting aerodynamic performance overall.

Engine Upgrades

ECU tuning helps get the most out of your Porsche engine, while a sport exhaust improves outflow and delivers a raucous exhaust note. Overall, power in the 4.0-liter flat-six engine jumps to 520 horsepower and 346 pound-feet of torque.
