Koni FSD Shocks BMW E90/E92/E82

The KONI FSD (Frequency Selective Damping) shock is an excellent balance of great road handling characteristics with no-compromise comfort levels. It's a two-in-one solution from KONI that doesn't require the installation of sophisticated electronics, cables or sensors. Firmness for sporty driving on even road surfaces. Smoothness for a comfortable ride on uneven road surfaces.


How It Works
In standard shock absorbers the main damping characteristic is defined by the oil flow going through the piston assembly.

Combining it with the FSD feature, KONI added a special valve that controls an oil flow parallel to the one going through the piston rod. This parallel oil flow is closed by the FSD feature, giving a rise in damping force almost linear to the time that the piston is moving in one direction.

Put simply
The FSD feature is a hydraulic amplifier that delays the build up of pressure. In some ways an extra tuning option has been created in order to get the best possible combination of handling and comfort.

Since it is an integrated part of the hydraulic valve system inside the damper, no additional cables, sensors or any other electronic devices are needed to operate an FSD damper.

Bilstein PSS Fully Adjustable Coilover System

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.

H&R Sport Cup Suspension Kit

H&R's Sport Cup Kit contains a specifically matched shock and spring set designed to provide aggressive performance and sleek-styling in one, ready-to-go package.

The kit includes a specially developed progressive spring tuned explicitly for your car and then matched to custom-valved performance sport shocks. This suspension kit on the 135i will lower the ride height more than 2.2" in the front and 1.5" in the rear for optimum handling and a super-low look at an affordable price.

Sonic Tuning Suspension

Features:
• Full length adjustment system on lower mount
• Separate ride high and pre-load adjustments
• Aluminum alloy construction: lower mount, top mount, spring seat and locks
• Multi-positional manual damping force adjustment *
• Forged aluminum top mount
• Compression and rebound: Each application has a different number of manual damping adjustments
• Adjust damper rate by touch of a knob.
• 12 level adjustable damper - adjustable dampers allow fine-tune the suspension stiffness to best suit the driving condition.
• Scm440 hardened piston rod: special high strength grade material with extra hardened process effectively improves the chances again deform, fracture and leakage.
• Special formulated oil – stable and durable high quality oil seal can minimize any suspension failures or oil leaking to increase durability.
• Racing suspension fluid – high performance suspensions fluid can effectively stabilize the damper force and ensure suspensions condition under severe driving.
• Inner polished seamless steel tube – quality high strength tubes ensure the strength of the struts (cylinders) the micro finished inner surface ensures a precise and smooth action, which can reduce the changes of fluid leakage and prolongs struts endurance.
• Mono tube design; come with quick response and comfort suspension fluid is separated from high-pressure gas in order to reduce damper failure.
• Advanced formulated rubber parts: effectively increase the endurance and help eliminate abnormal noises.
• Forged aluminum alloy top mount: increase the strength and effectively reduce the weight, and provides sensitive driving feedback.
• Sae9254 spring: high strength material formed spring effectively minimizes deformation.
• 6061 t6 aluminum alloy plate: lighter than normal steel parts.
• Improve the performance of the shock absorber and increase controlling

H&R Coilovers

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.

Cross Coilover Suspension Kit

CROSS Competition coilover systems for the High Performance BMW. The Competition Series is the 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 Sport / Race Springs

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&R Anti-Roll Bar

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.
