Description
BC Racing ER coilover kit Nissan Skyline GT-R R33 R34 (95-01) 9/7 kg/mm
The BC Racing ER coilover kit GT-R R33 R34 (part number D-08-ER) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Nissan Skyline GT-R R33 (BCNR33) and GT-R R34 (BNR34), model years 1995 to 2001. The spring rate is 9 kg/mm front and 7 kg/mm rear.
The ER series is BC Racing’s kit for serious track and competition use, and for the GT-R R33 and R34 it comes with stiffer springs than the BR, DS and ZX: 9 kg/mm front and 7 kg/mm rear. The damper is a monotube with dual piston and external reservoir, with fully synthetic oil with a very high viscosity index.
You set compression and rebound independently of each other, each with 30 clicks. The damping is digressive, the ride height is infinitely adjustable via the damper body, and the kit comes with camber plates, with rubber top mounts as an option.
Key benefits
- 2-way adjustment: compression and rebound each separately with 30 clicks.
- 9/7 kg/mm: stiffer than the BR, DS and ZX for the GT-R.
- External reservoir: with dual piston.
- Synthetic oil: with a very high viscosity index.
- Digressive damping: aimed at track use.
- Concave lock ring: the ride height stays put.
- Camber plates: rubber top mounts are optional.
- Rebuildable: the dampers can be rebuilt.
Suitable for
Nissan Skyline GT-R R33 (BCNR33) and GT-R R34 (BNR34), model years 1995 to 2001, both with all-wheel drive. Not for the rear-wheel-drive R33 GTS and R34 GTS; BC Racing has dedicated kits for those.
- Serious track days and club races
- A GT-R that is mainly driven on track
- Adjusting compression and rebound separately

Fitting and delivery
The ER kit replaces the original dampers and springs of the GT-R R33 or R34. We recommend having it fitted by an experienced mechanic and then having a wheel alignment done. Start with the damping in the middle and change one setting per session. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily does not have the kit, you can still order it and we will let you know the delivery date.
The BC Racing ER for the Skyline GT-R R33 and R34 has 9/7 kg/mm springs and is 2-way adjustable, with 30 clicks for compression and 30 for rebound.
Why choose this ER coilover kit GT-R R33 R34?
With a GT-R on track you want to be able to adjust more than a single knob. The ER gives you separate settings for compression and rebound, so that you can, for example, limit diving under braking without changing the rebound. The stiffer 9/7 kg/mm springs and the external reservoir make this a kit for a GT-R that spends a lot of time on track.
