looks like for the front one would have to buy new lower A Arms, for the rear dunno. Looks intresting. See below.
New Second Generation E-segment Architecture Delivers Maximum Grip With World-class Ride and Handling
Performance handling requires maximum grip, and the new 2011 Dodge Challenger SE and R/T models feature redesigned front- and rear-suspension geometries with premium suspension hardware for world-class ride and handling.
At the heart of Dodge Challenger’s new suspension design are isolated, lightweight front- and rear-suspension cradles that create a rigid assembly needed for precise performance.
At the front cradle, new monotube front-shock absorbers, springs and a repositioned lower-front shock-to-suspension-link bushing deliver improved control, ride and comfort. Combined, these suspension components provide improved handling and durability, while reducing the harshness from road bumps compared with the previous Dodge Challenger. In addition, all-new front-suspension hydrobushings — a premium suspension component — reduce ride harshness and prolong smooth braking characteristics.
At the rear, the new 2011 Dodge Challenger’s five-link rear-suspension design features new roll-steer geometry, allowing independent control of camber and toe suspension movement for world-class handling. All-new monotube shock-absorbers and springs make the ride more refined, while improving handling and dynamics. Premium urethane jounce bumpers and suspension links with rubber shock absorber bushings help the Challenger’s rear suspension contribute to a quieter interior cabin. In addition, new upper and lower spring-seat isolators provide additional dampening to Challenger’s rear suspension to deliver smooth engagement over bumps.
A more aggressive front- and rear-camber geometry improve, the all-new Dodge Challenger’s road-holding capabilities. Set at -1.0 degrees in the front and -1.75 degrees in the rear, Dodge Challenger is set up for high-speed cornering with its tires leaning inboard at the top relative to the body. New larger diameter front- and rear-stabilizer bars keep the chassis nimble during cornering and make body lean a thing of the past.
Improved Performance Steering Feel With Energy Saving Electro-hydraulic Power Steering (EHPS)
An all-new electro-hydraulic power steering (EHPS) system transmits precise road feel to the driver and improves on-center tracking and fuel economy.
Depending on the “control mode” within the EHPS system, the system applies variable steering effort to different driving conditions. EHPS analyzes steering angle, vehicle speed, engine rpm and chassis control systems 13 times per second for precise performance-handling feel. When the Dodge Challenger is stationary or moving at low speeds, the hydraulic pump increases power assistance for a lighter steering-wheel effort. The pump reduces steering assistance at highway speeds to give the performance coupe a firmer feel, and as a consequence, the system delivers a fuel savings of up to 1.5 percent by consuming less energy than a belt-driven pump.
Updated Exterior Enhancements Improve Form and Function
To match its unmistakable muscle-car styling, upgraded powertrain and improved handling capabilities, the new 2011 Dodge Challenger features performance-driven exterior enhancements.
At the front of the new Dodge Challenger’s wide stance is a restyled trapezoidal front air dam with a larger opening to cool the legendary Hemi V-8 or potent Pentastar V-6 engine. Providing additional downforce is a larger “duck bill” front spoiler in black to match the coupe’s lower sill.
Larger 18-inch aluminum wheels are now standard equipment on the Dodge Challenger and provide a more athletic stance with wider tires. For added style and performance handling, the Dodge Challenger SE with the new Rallye package now offers the all-new Super Sport Group, providing new five-spoke 20 x 8-inch chrome-clad aluminum wheels and even wider low-profile tires. For a touch of nostalgia, Challenger’s iconic bright racing-style fuel-filler door is now standard on all models.
Topping off the new Dodge Challenger SE and the new Challenger Rallye’s good looks are dual-chromed exhaust tips integrated into the lower rear fascia.
