Kenny Brown Mustangs are back – with a vengeance! Whether it's Spirited Touring, Performance Street, Track Day or Full Competition - Nothing Comes Close. With Incredible Performance, Superior Handling, Unparalleled Driver Confidence and a Fantastic Driving Experience – Kenny Brown Mustangs truly are, Best in Class
I’m back building best-in-class Mustangs again and it feels great! The 2013-2014 GT-4 Series is the fourth generation of high-performance Kenny Brown Mustangs, whose DNA goes all the way back to the 1986-1987 Saleen-R race cars I engineered, built and directed to win four National Championships in endurance sports car racing.
The latest S-197 Mustang with the awesome 5.0L Coyote engine has given me an outstanding platform to work my magic. This past season we have spent time at a variety of tracks around the country and burning up the highways developing, testing and validating the different components and packages for my 2013-2014 GT-4 Series Mustangs.
As always, all my cars have base package content with an extensive option list to choose from to make your Kenny Brown Mustang your very own. And, as in the past, each is custom, hand crafted and bespoke to your individual needs, desires and budget. My Fourth Gen Mustangs are great cars.
The GT4 nomenclature comes from my racing roots, and the GT-4 class in international FIA sports car racing designates production-based cars modified for racing that retain the original OEM architecture. In the case of the GT4 Series Mustangs, we retain the OEM architecture, but in my typical fashion make significant upgrades and improvements to offer the best driving and performing cars you will ever experience.

The automatic combined with traction control make it a brilliantly quick, yet amazingly civil car just driving around town. This is the kind of Mustang that you can seriously spank a Viper with at the toll booth grand prix - with a cup of coffee in your hand.
If you're feeling really sporty, click the traction control into Sport Mode, drop the shifter into Select, and unleash the beast. The SelectShift lets you select gears up and down manually with a touch of a button, and the traction control in Sport Mode gives you tire smoking capability, but you better be hanging on to the steering wheel and forget the coffee because this speed monster demands respect.
