Description
Nissan Skyline R34 GTS RWD (rear eye) ER34 (98-01) BC Racing ER Series Coilovers | 8/5kg.mm
BC Racing ER Series Coilovers are precision-engineered suspension components specifically developed for the Nissan Skyline R34 GTS RWD (rear eye) ER34 (98-01), featuring a 8/5kg.mm spring rate that delivers responsive handling and reduced body roll during aggressive driving. These fully adjustable coilovers offer independent height and damping tuning across both axles, enabling enthusiasts to fine-tune their R34's suspension geometry for track performance or daily driving comfort. BC Racing's proven reputation for quality makes the ER Series an ideal choice for drivers seeking measurable improvements in cornering grip and ride control on their classic Skyline.
BC Racing ER Series Coilovers
The BC Racing ER Series brings with it the high quality and unique features of the BR and DS Series, with the additional benefit of external reservoirs and the ability for the driver to individually adjust and set compression and rebound damping rates. Separating the adjustment for compression and rebound allows the car to be dialled in to exact requirements — a level of precision not available with a single combined adjuster.
Key Features
- Digressive piston and damping curve
- 30 clicks of compression adjustment via the external reservoirs
- 30 clicks of rebound adjustment from the top of the damper
- Ride height adjustment separate to spring preload
- Monotube damper design
- Pillowball top mounts
- Bearing mounted upper spring platform
- Camber adjustable top mounts (depending on model)
- Tapered bottom mount locking collar to prevent collar working loose
- Custom spring rates available
- All spare parts available with low lead times
- Dust boot to protect damper seals
- 1 year manufacturer warranty
Separate Compression and Rebound Adjustment
Compression damping controls how the car transfers weight to its tyres during braking — allowing the front to load progressively for maximum braking grip and enabling trail braking into a corner. Rebound damping controls how the suspension responds as load is released on corner entry, keeping the front end hooked up rather than snapping back and causing understeer. Tuning each independently, without one adjustment affecting the other, is a significant advantage for circuit use — corner exit speed is ultimately determined by how well the front stays loaded through the entry phase, and that comes down to the balance between compression and rebound.
