Description
BMW E39 5 Series Sedan (95-04) BC Racing BR coilover kit 5/4.5 kg/mm
The BC Racing BR coilover kit E39 (part number I-06-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW 5 Series E39 Sedan with rear-wheel drive, model years 1995 to 2004. The spring rate is 5 kg/mm front and 4.5 kg/mm rear.
The E39 is a spacious sedan with rear-wheel drive that steers a good deal more sportily with the right suspension. This BR kit from BC Racing is made for the E39 Sedan; for the Touring, BC Racing has a separate kit with part number I-42-BR-RA.
As an all-round series, the BR is aimed at daily use with the occasional track day or autocross. Monotube dampers with a linear piston, 30 clicks for compression and rebound together and a ride height that you set independently of the spring preload make the 5 Series more stable and more direct without losing its suitability for long journeys.

Fitting and delivery
The kit is vehicle-specific and replaces the original dampers and springs of the E39 Sedan. We recommend having it fitted by an experienced mechanic. On some cars the pillowball top mount at the front requires a small modification to the upper mounting; if in doubt, contact us. After setting the ride height, have the wheel alignment checked. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily has the kit out of stock, you can still order and we will keep you informed of the delivery date.
For the BMW 5 Series E39 Sedan, BC Racing supplies the BR coilover kit I-06-BR-RA with 5 kg/mm front and 4.5 kg/mm rear.
Why choose this BR coilover kit E39?
An E39 on tired original suspension feels sluggish and keeps bobbing after bumps. With this BR kit you get a more stable, more direct car whose height and damping you decide yourself, while it remains suitable for long journeys and daily use. Because the dampers are rebuildable, the kit lasts a long time.
