Cross Coilover Suspension Kit
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.

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.

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.

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.

These Koni FSD's Fit:

E92 BMW 328i/335i Coupe
E82 BMW 128i/135i Coupe
