BC Racing Coilovers – Honda Civic/Cr-X (Rear Eye) (88-91) [EF9/ED]

BC Racing Coilovers Honda Civiccr X are a direct-fit damper and spring package, sold as a complete four-corner kit. Chassis code EF9/ED. Fits 88-91 cars. Default spring rates are front 9 kg/mm / rear 4 kg/mm.

Because height is adjusted at the lower bracket, dropping the car does not add spring preload. You keep the full damper stroke instead of running out of travel at the bottom.

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 Honda Civic/Cr-X (Rear Eye)?

• BR Series gives you 30-way rebound adjustment and full height adjustment independent of spring preload.
• ER Series gives you external reservoirs for more consistent damping under sustained load.
• ZX Series gives you raised ride height for soft-road and overland use.

Spring rates and what is in the box

This kit ships at 9 kg/mm front and 4 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 Honda Civiccr X

Set the height first, settle the suspension by rolling the car, measure, then adjust. Only book the alignment once the ride height is final, because camber and toe both move as the car comes down.

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.

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 Honda Civiccr X questions

Will BC Racing Coilovers Honda Civiccr X fit without modification?

The kit is cut to the Honda Civic/Cr-X (Rear Eye) damper and strut dimensions and uses the standard mounting points on the EF9/ED chassis. No cutting or welding is needed for a standard car.

How low will the Honda Civic/Cr-X (Rear Eye) 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 Honda Civiccr X come with?

Front: 9 kg/mm / Rear: 4 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.
