The Bilstein PSS9 Performance Suspension System features 9 dampening adjustments. It includes adjustable monotube gas shocks with nine precise compression and rebound settings from comfort to competition. The front and rear springs have progressive rates and allow accurate adjustment of the vehicle ride height and center of gravity. Professional installation recommended.

CROSS Competition coilover systems for the High Performance BMW. The Competition Series is our top of the line coilover system. It features a lightweight design with a 15 way dampening adjustable monotube damper. With its high strength and durability, the Competition Series insures that it will last through any type of driving condition. The front damper features a 40 mm piston and the rear has either a 40 or 45mm piston depending on application. The ride height adjustability is independent from the spring perch so adjusting ride height does not compromise the spring rate or rebound and compression of the damper. All coilover systems come with a cool bend linear spring that offer last precision steering and handling. Spring rates are also custom tailored to each system and driver's preference. All Competition Series coilovers include front camber adjustable pillow ball upper mounts and most rear includes pillow ball mounts depending on application. Larger luxury vehicles have a softer damper for a sporty luxury feel and also allowing a lower ride height. Based off of racing technology, the Competition Series Coilover is a street performance suspension, customizable for full track use.

H&R Anti-Roll Bars are the perfect complement to H&R springs, coil-overs, performance shocks and cup kits.

Designed to reduce body roll, increase lateral stiffness and improve handling, H&R Anti-Roll Bars are crafted from spring steel that is both stronger and more resilient than other materials. H&R Anti-Roll Bars are bent on proprietary machines designed by H&R that seamlessly produce complex curves helping to ensure a perfect fit for your vehicle.

All H&R Anti-Roll Bars have been shot-peened, heat-treated and feature precision forged ends. Many applications have multiple end link mounting points for adjustability. Also included are H&R's exclusive bushings made from a urethane/Teflon composite that helps to eliminate squeaks and doesn't require lubrication.

Like all H&R components, H&R Anti-Roll Bars are made in Germany and are powder-coated for long lasting good looks and durability on the street and track.

Racing improves the breed. H&R Threaded-Body Coil-Over Suspension Kits come directly from engineers who design and develop racing suspensions.

Blueprinted as coil-overs (not just a modified shock body), the H&R units are hand-assembled in Germany by H&R Speziafedern under rigid ISO 9001 and German TÜV standards. Strict attention to the function of the complete suspension system is the number one design priority.

Their threaded body means that the outside of the strut or shock tubes are threaded like a bolt. This allows the threaded spring perch to be moved up or down to fine-tune the ride height, optimizing looks and handling.

Equally at home on the street or the track, H&R Coil-Over Suspension Kits provide enhanced performance, improved corner-holding ability and a sleek, aggressive stance for performance driving characteristics without harshness.

H&R Sport Springs are designed and engineered for each particular application and are the correct spring rate for low aggressive looks, high performance handling and no ride harshness! H&R Sport Springs will lower your vehicle approximately 1.25-2.0 inches (depending on the make and model of your vehicle) and should be matched with high-quality, sport-tuned shock absorbers. Camber correction may be necessary.


For the discerning enthusiast that wants the ultimate in performance and an aggressive look, H&R Race Springs are the perfect solution. H&R Race Springs will lower your vehicle approximately 1.75-2.5 inches (depending on the make and model of your vehicle) and should be matched with high-quality, sport-tuned shock absorbers. Camber correction may also be necessary.

H Sport-designed coils for the E46 cars are unique in that they provide a much lower stance yet ride similar to a stock M3. H Sport’s variable rate coils will lower the 3 series just over ½” up front and ¼” rear. Ride quality is excellent . Each H Sport coil is powdercoated H Sport blue.

The BMW 335 has an aggressive camber curve in bump travel which is especially noticeable on lowered cars. Excess negative camber causes premature inside edge tire wear and reduced traction on acceleration. The Hotchkis adjustable Camber Links allow for precise rear camber alignment that is easily optimized for street or track driving.
