YSR Pro Plus Racing 2-Way Coilovers Audi S5 B9 Quattro B8/B8.5 08-17

YSR Pro Plus Racing 2-Way Coilovers for Audi S5 B9 Quattro B8/B8.5 (2008-2017) – 2-Way Adjustable Track Coilovers with External Reservoirs

Yellow Speed Racing Pro Plus Racing 2-Way coilovers for the Audi S5 B9 Quattro B8/B8.5 (2008-2017). They are built for track events and competition, for drivers who want fine control over how the car is damped.

Compression and rebound damping are adjusted separately, and full-length ride height adjustment lets you set the height without changing spring preload or damper travel.

External reservoirs, either hose-mounted or piggyback depending on the car, add oil capacity so the dampers stay cool and consistent through long sessions. Reservoir canisters are high-grade steel or aluminium alloy with an anodised 7075 alloy base, and the damper bodies are electroplated to resist corrosion.

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.

How is the damping adjusted?

Compression and rebound each have their own adjuster, so they can be set independently.

What is the difference between the 2-way and 3-way?

The 2-way adjusts compression and rebound separately. The 3-way splits compression into low-speed and high-speed, giving finer control for track use.

Where does the reservoir go?

Depending on the car, the reservoir is either piggyback mounted on the damper or connected by hose so it can be mounted in a suitable place, such as the engine bay.

Can I adjust the ride height without changing preload?

Yes. Full-length adjustment lets you set the ride height independently of spring preload.

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?
