BMW E39 5 Series Touring (95-04) BC Racing DS coilover kit 5.5/5.5 kg/mm

The BC Racing DS coilover kit E39 Touring (part number I-42-DS-DA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW 5 Series E39 Touring with rear-wheel drive, model years 1995 to 2004, not for cars with self-levelling suspension (SLS). The spring rate is 5.5 kg/mm front and 5.5 kg/mm rear.

For the E39 Touring, BC Racing also has a DS kit, the track-focused series with a digressive piston that damps more firmly at low piston speeds (0 to 50 mm/s). Please note: just like the BR kit, this DS is not suitable for a Touring with self-levelling suspension (SLS).

The DS is intended for those who drive the Touring sportily and occasionally take it on track. You adjust the damping in 30 clicks and set the ride height independently of the spring preload. The satin chrome damper body makes the DS recognisable.

Fitting and delivery

Before ordering, check that your E39 Touring does not have self-levelling suspension (SLS), because this kit is not suitable for it. The DS kit is vehicle-specific and replaces the original dampers and springs; 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 adjusting the 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 does not have the kit in stock, you can still order and we will keep you informed.

The BC Racing DS for the BMW E39 Touring has a spring rate of 5.5/5.5 kg/mm and is not intended for cars with self-levelling suspension (SLS).

Why choose this DS coilover kit E39 Touring?

If you also want to use your E39 Touring on track, the DS gives you a kit built for exactly that. The digressive damping keeps the Touring flatter when turning in and braking, and in 30 clicks you tune it to how and where you drive.
