BC Racing Coilovers – Daihatsu Copen (02-12) [L880K]

Fitting BC Racing Coilovers Daihatsu Copen gives you adjustable ride height and adjustable damping on the factory mounting points. Chassis code L880K. Fits 02-12 cars. Default spring rates are front 4 kg/mm / rear 3 kg/mm.

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 Coilovers Daihatsu Copen specification

Available kit configurations

Each configuration is the same damper and spring package with a different top mount arrangement. The kit code is the BC Racing part number for that build.

Which series for the Daihatsu Copen?

• BR Series gives you 30-way rebound adjustment and full height adjustment independent of spring preload.

Spring rates and what is in the box

This kit ships at 4 kg/mm front and 3 kg/mm rear. The rates are matched front to rear for a balanced setup on the road. 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. Top mounts depend on the configuration you pick from the table above. 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 Coilovers Daihatsu Copen

Set corner heights on level ground with the driver weight accounted for, then roll the car and settle the suspension before measuring again. Ride height changes on the bracket, damping on the adjuster knob.

Set the adjusters mid-range to begin with. Adjust in small steps and change only the front or only the rear at a time, otherwise you cannot tell which change did what.

The kit is rebuildable and the springs are a standard ID, so a rate change later is a spring swap rather than a new set of coilovers.

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

BC Racing Coilovers Daihatsu Copen questions

Will BC Racing Coilovers Daihatsu Copen fit without modification?

The kit is cut to the Daihatsu Copen damper and strut dimensions and uses the standard mounting points on the L880K chassis. No cutting or welding is needed for a standard car.

How low will the Daihatsu Copen 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 Coilovers Daihatsu Copen come with?

Front: 4 kg/mm / Rear: 3 kg/mm 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.
