Description
BC Racing ER coilover kit Nissan Silvia S14 200SX camber/caster top mounts (95-99) 10/8 kg/mm
The BC Racing ER coilover kit S14 camber caster (part number D-14-ER) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Nissan Silvia, 200SX and 240SX on the S14 platform, model years 1995 to 1999. The spring rate is 10 kg/mm front and 8 kg/mm rear.
This version combines the 2-way adjustable ER dampers with camber/caster top mounts. A kit for anyone who wants to adjust not only the damping but also the geometry on the track or the drift circuit.
Like every ER kit, it works with monotube dampers with a dual piston and an external reservoir. You adjust compression and rebound each in 30 clicks, independently of each other. The digressive piston keeps the body calm, while the wheels can move freely over bumps.
The spring rate is 10/8 kg/mm, a firm and balanced setup for intensive track use.
Key benefits
- Camber/caster top mounts: adjust the wheel position at the top as well as the damping.
- 2-way adjustment: 30 clicks compression and 30 clicks rebound, independent.
- External reservoir with dual piston: the damping stays consistent during long sessions.
- Spring rate 10/8 kg/mm: firm and balanced between front and rear.
- Digressive character: a flat car on turn-in, grip over kerbs.
- Ultra-high viscosity index oil: fully synthetic, resistant to high temperatures.
- Rebuildable: the dampers can be rebuilt.

Fitting and delivery
After fitting, first set the ride height and then put the top mounts in a neutral position, and have the wheel alignment done by a specialist who can measure camber and caster. Also check the clearance around the reservoir hoses. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. Out of stock? You can still order and we will keep you informed of the delivery date.
Damping and geometry belong together: with adjustable top mounts you turn a good ER kit into a kit that is set up precisely for your car.
Why choose this ER coilover kit S14 camber caster?
Because it puts everything in your hands at once. You do not need to buy separate top mounts, and you can tune camber and caster to your tyres and your driving style. Together with the 2-way damping and the 10/8 kg/mm springs, this is a complete basis for a serious S14.
