ROUSH® 427R Trak Pak™ Mustang Brakes and Suspension Now Available

LIVONIA, Mich. – When ROUSH® Performance unveiled the 427R Trak PakTM Mustang last summer, it was universally heralded by media and consumers alike for the incredible handling and stopping ability.  Now, those same components are available to install on any 2005-2008 Ford Mustang.


403151-377x310 The Trak PakTM suspension features adjustable rebound front and rear dampers which allow different settings to be utilized for street or racetrack driving.  The front and rear ride height is adjustable up to 35 mm lower (1.4-inches), and there is the ability to dial in up to three degrees of negative camber.  The kit comes with high tensile strength linear rate springs with tender coils and matching elastomer jounce bumpers. The suggested retail price is $2,499.99 (part number 403151).

The 6-piston brake calipers are constructed from an aluminum forging which will give better feel under extreme braking conditions such as driving hard into a turn on a racetrack.  Different piston sizes minimize pad taper for a longer pad life and a firmer brake pedal.  The kit includes 14-inch two-piece slotted rotors and a larger brake pad than either OEM or the ROUSH 4-piston calipers which leads to lower pad temperatures and better pad life.  The suggested retail price for the 6-piston brake kit is $3,697.99 (part number 403144).

The development and testing of both the ROUSH® Trak PakTM suspension and brake packages were done over the course of several months by logging thousands of miles on the street and at a variety of racetracks, such as Road America (Elkhart Lake, Wis.), Gingerman Raceway (South Haven, Mich.), and Hallett Motor Racing Circuit (Hallett, Okla.).  For more information on either of these products, or the complete line of styling, handling and performance parts ROUSH® offers for the Ford Mustang, visit
