RENNtech AMG GT63 MONSTER
The RENNtech AMG GT63 Monster is a custom-built, one-of-a-kind masterpiece. Powered by our formidable RIIIx performance package, this example has been further upgraded and personally customized by RENNtech founder Hartmut Feyhl.
Delivering astonishing power and acceleration, the Monster stands as the ultimate evolution of the RENNtech AMG GT63 4-Door Coupe (X290) platform — a street-legal powerhouse without equal in the world of four-door performance.
The Monster is powered by the Mercedes-AMG twin-scroll M177 BiTurbo V8, equipped with RENNtech’s Stage II high-performance turbochargers that feature larger inducer and exducer wheels along with a special core assembly for less rolling resistance and zero lag.
To ensure the engine receives the necessary air flow and fuel supply, the Monster is fitted with an integrated carbon fiber air intake system with a 30% larger filter surface, and high-pressure fuel pumps. The exhaust system features RENNtech stainless-steel high-performance downpipes with free-flow 200 cell catalytic converters and upgraded performance mufflers designed for the AMG GT63 chassis.
The ultimate performance vehicle - designed and developed by RENNtech in Stuart, FL.
