Which KENNY BROWN GT4 Series Mustang Hits YOUR Performance SWEET SPOT? 

Marilyn Mustang GT4 Kenny Brown Cars Heritage Series

MEET MARILYN

A Kenny Brown's GT4/CS-R (Club Sport Racer) Mustang that is outrageously fast, exhilarating to drive and pretty much dominates at track days. The GT/CS-R is the top-of-the-range of the Kenny Brown naturally aspirated line of GT4 Series Mustangs and the best premium late-model track car Kenny offers.

Why the name "Marilyn" you may ask? As a tradition, we (as well as our customers) have a penchant to name our special custom-built cars rather than reference them as just a number. Often the name has a tendency to encompass the personality of the particular car as well.

Marilyn is named after Marilyn Monroe and has rightfully earned her name. She's a really fast, drop-dead gorgeous platinum blonde that everybody wants to get their hands on, but no one can catch.

Aside from being incredibly fast, extremely well-balanced with precision handling and totally amazing to drive. It’s hard to find the words to describe the exhilaration you get when driving Marilyn (or any other Kenny Brown GT4/CS-R Mustang for that matter) other than she’ll take your breath away - in a very, very good way. So the name Marilyn fits!

So, What Will You Name Your Kenny Brown Mustang?

Kenny always builds his Performance Platform first before adding any more power and the GT/ST is no exception with Cold-Air Kit, Engine Tune and Sporty Exhaust nudges the power up. Oh, and don’t forget your GT/ST is a genuine Serialized Kenny Brown Mustang.

Wicked Fast Supercharged Mustangs

Mustang GT4 Supercharger Kenny Brown Cars

Wicked fast power with incredible driving dynamics describes Kenny Brown Supercharged GT4 Mustangs with completely engineered performance upgrades to all major systems to support the added power.

The Kenny Brown Supercharged Performance Platform includes upgrades to - cooling, suspension, wheels, tires and brakes, with even a little aero for high-speed stability, relevant to the added power from the Supercharger.

Interesting Note: Mustang GT’s are engineered by Ford to handle around 460hp; they weren’t engineered to add another 250hp-310hp. That is why the GT500 cost over $35,000 more than the GT. A Porsche 911 Turbo is around $100k more than the base 911, because both of these the cars are reengineered to support the added power. This is why Kenny reengineers his Supercharged Kenny Brown Mustang's “Performance Platform” power foundation to support all the added power.

Kenny Brown Supercharged Street Fighter Mustang 710hp

YOU CAN HAVE IT ALL - POWER AND CONTROL

 

Kenny Brown Supercharged Street Fighter Mustangs 710hpThe Kenny Brown GT4/S Street Fighter is Kenny’s answer to those Ford dealerships and others that just throw a big supercharger on a base Mustang and sell them without ANY thoughts about safety or system upgrades to support the added power. Kenny feels that the advertised so called $40k supercharged dealership base Mustangs are dangerous to drive and they are definitely not looking out for your best interest you.

The Kenny Brown GT4/S Street Fighter gives you just enough added upgrades to key systems (cooling, suspension, wheels, tires, brakes) to ensure your Street Fighter can handle the extra horsepower. Plus, it rides, drives, feels, and performs like a Legendary Kenny Brown Mustang.

In a Straight Fight, the Street Fighter will kick a $40K Dealership Mustang’s butt all day long and twice on Sunday.

Kenny Brown GT4/Super-S Supercharged Mustang

GT4/Super-S Supercharged Mustang - 770hp

THE PORSCHE TURBO OF MUSTANGS

Wicked fast supercharged power with superb handling, unmatched control and driver confidence for an unforgettable exhilarating and fun driving experience. 

In some sense you can think of the 770hp supercharged Kenny Brown GT4/S Mustang from an engineering perspective, like a Porsche Turbo. When Porsche adds big turbo power to the 911, they basically re-engineer the entire car to support all the added power of the turbo with pretty much bigger, better everything. 

When Kenny adds the fierce power of a supercharger, he doesn't just add a supercharger. He re-engineers the entire car to support the added power with premium performance upgrades to all the major systems.

Where others bolt on a supercharger and maybe a few common off-the-shelf parts, Kenny takes a much, much deeper dive. With custom premium components built to his stringent specifications, all engineered to command and control the potent 770hp with confidence.

Bigger brakes, totally upgraded suspension, bigger better cooling, bigger better wheels & tires, better fuel systems, aero for high-speed stability and the list goes on. All part of the Kenny Brown “Magic” that gives you a fantastic, spine-tingling experience with unmatched driving confidence.
