BC Racing Coilovers for BMW 3 Series E46 Non-M3 98-05

The BR Series Model is the perfect choice for street driving and the occasional road course or autocross duty. With easily accessible adjustment knobs for fine-tuning compression and rebound, ride height adjustment independent of shock stroke and spring preload, having a performance coilover system has never been easier. The driver chooses how low or high the vehicle sits (no preset ride height here!) and a BC Racing patented concave lower locking ring keeps it locked securely in place. Most systems can be upgraded to pillowball mounts to proved the most feedback possible from the suspension and to sharpen steering response. BC Racing front camber plates also allow a driver to get the perfect alignment setup without compromise. Each of these features is offered, while providing a strong, attractive coilover system at a reasonable price.

• MONO-TUBE SHOCK DESIGN
• LINEAR PISTON AND DAMPING CURVE
• HEIGHT ADJUSTMENT VIA SHOCK BODY, NOT SPRING
• 30-CLICKS OF DAMPING ADJUSTMENT (COMPRESSION/REBOUND) SIMULTANEOUSLY
• FRONT CAMBER PLATES STANDARD ON APPLICABLE KITS
• REAR CAMBER PLATES AVAILABLE ON APPLICABLE KITS
• CUSTOM SPRING RATES AVAILABLE FOR MOST APPLICATIONS

**Please note that not all vehicles use camber plates in the front and/or rear. Some vehicles reuse OEM upper mounts.

The ER Series features large external reservoirs front and rear, independently adjustable rebound and compression, plus a mono-tube twin-piston design. The large external reservoirs allow for a higher oil capacity that translates to faster heat dissipation during extended road course use. Additionally, the external reservoirs house the secondary piston, which allows for the independent adjustment of compression, separate from rebound adjustment. The ER Series coilover is the perfect system for the driver who wants to dial in his or her suspension by varying the compression and rebound settings to fit a specific driving style and performance demand.

• MONO-TUBE DAMPER WITH TWIN PISTON DESIGN
• HEIGHT ADJUSTMENT VIA SHOCK BODY, NOT SPRING
• 30-CLICKS OF DAMPING ADJUSTMENT (COMPRESSION/REBOUND) SIMULTANEOUSLY
• FRONT CAMBER PLATES STANDARD ON APPLICABLE KITS
• REAR CAMBER PLATES STANDARD ON APPLICABLE KITS
• CUSTOM VALVED TO MATCH THE DRIVERS REQUESTED SPRING RATES

BC Racing's inverted RM Series model includes all of the great features of the BR Series model, then takes everything up a notch. The inverted coilover system moves vital damper fluid away from detrimental heat sources to avoid overheating the fluid which can cause damper fade under extreme use. Inverted dampers handle high lateral loads more efficiently and offer increased durability under extended road course sessions. Other advantages are the reduction of unsprung weight by moving the majority of the coilover mass to the chassis of the vehicle where weight can be more easily shaved. This is a durable coilover setup for those looking to attack a road course, hill climb or tarmac rally.
