Kenny's Build Notes


This was a fun project. The client had originally purchased a 2005 Roush Mustang and hated it. He wanted a Kenny Brown Mustang with a little snort in it. This was primarily going to be a street car and do occasional shows, but the car had to go when he put his foot down.


To meet his needs I started with the street focused KB Touring package then added a Vortech supercharger and other selected components to balance out his package, making it a Kenny Brown GTS.


In the performance foundation I gave most of my attention to the rear suspension. Being a street car he didn't need the aggressive Club Sport stuff in the front, but he did need to improve grip and traction at the rear. Supercharging these new 3-valves was yielding plenty of horsepower well into the 400s. And, what good is all that power if you can't get it to the ground?


To further help the balance of the package, I off-set the wheels and tires (front to rear to give the rear more grip. I used 18”x9” front and wider 18”x10” wheels at the rear - Likewise with the max-performance tires - 275 fronts and 295 rears. This in combination with more aggressive (than the standard KB Touring package) rear suspension geometry and components will help balance the car and improve traction and grip. With all that extra power, this will help reduce those – Oh S*** - moments. Along those lines I added and Auburn Pro posi unit (the factory one quivers at this kind of power and grip) plus bigger Baer GTP brakes with beefy 14” rotors. I have a saying that if you're going to really GO – you'd better be able to really Whooooa. Trust me, with well over 400 horsepower in a Mustang, its gonna GO!


The other unique feature that the client wanted was a pair of Le Mans stripes, painted on all the way from front to rear. None of that “cheap vinyl strip junk”. Poof – his wish was our command – a pair of “painted” Le Mans stripes.
