BC Racing ZX-Series Coilovers Mercedes-Benz C-Class W205 14-21

BC Racing ZX-Series Coilovers for Mercedes-Benz C-Class W205 (2014-2021) – Height and Damping Adjustable, Corner Weight Adjustable

These BC Racing ZX-Series coilovers replace the standard dampers and springs on the Mercedes-Benz C-Class W205 (2014-2021) with a fully adjustable setup. You can set the ride height, damping and corner weights to suit the car, making them ideal for racing, track and drift use.

The ZX-Series is designed for racing, track and drift use. It offers 3-way adjustment with 30 clicks of rebound, 20 clicks of low-speed compression and 12 clicks of high-speed compression, and uses an upright damper design so the upper mount can be changed. External canisters and high viscosity index racing fluid keep performance consistent over long sessions.

Ride height is set by winding the bottom mount up or down the damper body rather than moving the spring, so full damper travel is kept whatever height you run. The lower spring platform also adjusts, so the car can be corner weighted for even tyre loading across each axle.

Installation

The coilovers replace the standard dampers and springs and bolt in to the original mounting points. Set the ride height and spring preload before final tightening, let the suspension settle, then recheck the height and have a four-wheel alignment carried out. We recommend professional fitting.

Keep a spare BC Racing C-spanner for adjusting the height and spring platforms.

Can I adjust the ride height?

Yes. Ride height is set by moving the bottom mount on the damper body, so you keep full damper travel at any height you choose.

How is the damping adjusted?

The ZX-Series uses 3-way adjustment with 30 clicks of rebound, 20 clicks of low-speed compression and 12 clicks of high-speed compression. Start from BC's base setting and adjust front and rear in small steps to suit the road or track.

Are these suitable for daily driving?

They can be used on the road, but the ZX-Series is designed mainly for racing, track and drift use. For a car that is mostly driven on the road, our V1 or BR-Series kits are a better fit.

Can I get different spring rates?

The kit comes with 8/13kg/mm (F/R) springs as standard. If you need different rates, contact us before ordering and we will check what is available.

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?
