YSR Dynamic Pro Sport Digressive Coilovers for BMW 6-Series E63 (2003-2010) – Digressive Valved Coilovers for Track Days and Spirited Driving
Yellow Speed Racing Dynamic Pro Sport Digressive coilovers for the BMW 6-Series E63 (2003-2010). They use digressive valving for drivers who do track days, autocross and spirited road driving. This listing is for the 6 Cyl version.
Unlike a linear valve, a digressive valve gives its strongest damping at low piston speeds and then tapers off as speeds rise. That gives a sharp, controlled response to steering, braking and body roll, while still letting the suspension move freely over bigger, faster bumps.
Expect a firmer ride than standard at low speeds, and some extra road noise. These are a performance setup rather than a comfort-focused road suspension.

Installation
The coilovers replace the standard dampers and springs. Set the ride height and spring preload, let the suspension settle, then recheck the height and have a four-wheel alignment carried out. We recommend professional fitting.
Please note: Pillow ball upper mounts make a small amount of noise. This is normal and does not affect performance or safety. Yellow Speed Racing also offer hardened rubber upper mounts (R/U) for quieter running. Digressive coilovers are designed for track use and give a firmer ride at low speeds. No warranty is offered against damper-related noise.

What does digressive valving do?
It gives the most damping at low piston speeds for tight body control, then tapers off at high speeds so the car copes better with sharp bumps and kerbs.
Is it comfortable on the road?
It is firmer than standard at low speeds and can add some road noise, so it suits drivers who put handling first.
Is it suitable for track days?
Yes. It is designed for track days, autocross and spirited driving.
Will the pillow ball mounts be noisy?
They make a small amount of noise, which is normal. Hardened rubber upper mounts (R/U) are available for quieter running.
Do I need a wheel alignment after fitting?
Yes. Changing the ride height alters the suspension geometry, so a four-wheel alignment should be carried out once the car has settled.
What warranty is included?
Yellow Speed Racing products are covered against defects in materials and workmanship. Digressive coilovers are designed for track use and no warranty is offered against damper-related noise. Contact us for full terms.
