Sway bars transmit cornering forces from the outside wheels to the inside wheels, helping to keep the vehicle flat during cornering. This, in turn, reduces body roll and improves the driver's cornering confidence. OEM rubber sway bar bushings are designed with comfort in mind, allowing the sway bar to articulate while permitting additional movement, leading to less-than-ideal bar retention and causes unnecessary body roll.

Powerflex polyurethane sway bar bushings are firmer than factory rubber bushings, reducing body roll and keeping sway bars in check. Polyurethane bushings won't slop around like OEM bushings, allowing sway bars to function at their fullest potential.

Poweflex is a leading manufacturer of aftermarket suspension bushings. Using state of the art design and manufacturing, all replacement bushings are engineered to out-perform and out-last the ones that came in the car. Each line of bushings is meticulously tested and then re-tested to ensure perfect fitment and enduring quality through the life of the vehicle. A full lifetime warranty backs every one of their products and demonstrates the level of confidence and commitment Powerflex has to their customers.

Adjustable Rebound Damping

The KW Variant 2 gives shock rebound control to give you more options in fine-tuning the handling of the car. The V2 includes the same features of the V1 kit, including -

• Adjustable Rebound with fixed compression settings - optimal ride comfort then dial in more grip and a better balance with less bodyroll than the standard suspension,
• Stainless steel strut/shock bodies and composite spring perches for superior corrossion resistance,
• Individually height-adjustable - Front = 30-60mm lowering; Rear = 20-50mm lowering,
• TUV approved lowering range and operation,
• Expert engineering and design for ease-of-use and long durability,

This kit is an excellent compromise between a fully-adjustable V3 suspension and the basic V1 street kit. It's great for someone who does not want to make complicated and time-consuming shock adjustments. Just dial in the rebound for more grip and less body motions. Set it back for a compliant street ride.

Coil over suspensions are better engineered suspension options compared to a standard shock + spring package. Since the springs and shocks in a coil over are designed by a team of engineers to work together, there is much better suspension travel and more precisely tuned specifications for spring and shock rates. Using separate shock and spring specs may result in premature coil bind or shock bottoming. And most coil over kits offer more features than the traditional packages. Coil overs are also more useful when larger wheels/tires are used because you can precisely set the ride heights to clear the new tires.

Fitment Note: Wheel spacers may be required depending on wheel/tire sizing and ride height setting.
