BC Racing DS Series Coilovers

BC Racing DS Series Coilovers replace the standard dampers and springs with an adjustable, rebuildable setup. Default spring rates are.

Height and preload are adjusted separately. Lowering the car on the bracket leaves the spring seat where it is, so you are not trading ride quality for ride height.

BC Racing DS Series Coilovers specification

Spring rates and what is in the box

Spring rates are matched front to rear for this application. Rates are chosen by BC Racing per application, so they suit a fast road and occasional track car as supplied. If the car is built for something more specific, a track weapon or a car carrying a lot of aero, the rates can be changed without replacing the dampers.

The kit covers all four corners and includes the dampers, springs, lower brackets, locking collars and the adjuster spanners. Anything that is worn on the car already, drop links, bushes, top mount bearings, is worth checking while the suspension is apart.

Fitting and setting up BC Racing DS Series Coilovers

Work on a flat floor, set the height on the lower brackets, then roll the car forward and back to settle everything before you take a final measurement. Alignment comes after the height is set, not before.

Start with the damping adjusters in the middle of their range and work from there. Wind towards firm for track work and back off for road use, changing one end of the car at a time so you can feel what each change did.

These are serviceable units. Spring rates can be swapped and the dampers rebuilt, so the kit can be re-specced as the car changes rather than replaced.

Worth reading if you are new to this: how a coilover works and why height and preload are separate adjustments.

BC Racing DS Series Coilovers questions

Will BC Racing DS Series Coilovers fit without modification?

The kit is cut to the BC Racing DS Series Coilovers damper and strut dimensions and uses the standard mounting points. No cutting or welding is needed for a standard car.

How low will the BC Racing DS Series Coilovers go on these?

Height is adjustable across the full range of the lower bracket. How low you can usefully run depends on your wheel and tyre size and how the car is used, so set it to suit how the car is actually used.

What spring rates do BC Racing DS Series Coilovers come with?

as standard. The springs are a standard ID, so rates can be changed later without replacing the dampers.

Do I need an alignment afterwards?

Yes. Camber and toe both move as the car comes down, so book the alignment once the ride height is set and the suspension has settled.

Are these road legal?

Adjustable suspension is legal for road use in the UK. Keep the ride height sensible, make sure nothing fouls at full lock or full compression, and tell your insurer the car has been modified.
