Kenny Brown GT4-CS Autobahn Edition Mustang

When Kenny Brown officially relaunched his performance brand last year we knew it wasn’t long before we would start to see new offerings from the legendary Mustang builder and racer. The company debuted the GT-4T Mustang Convertible at SEMA, and now have launched their latest vehicle dubbed the GT4-CS Autobahn Edition Mustang.

Designed for the track day enthusiast, the GT4-CS Autobahn Edition is built to order specifically for each customer depending on their experience and driving style and features a wide range of upgrades to make it the ideal club racer. Modifications have been selected specifically to handle the rigors of a full weekend of racing, from the fully adjustable suspension system and chassis braking to the Baer 6R Extreme+ braking system to the lightweight Forgeline wheels. The 5.0L V8 engine has also been tuned to 485 horsepower thanks to improved intake and exhaust flow.
