Description
Nissan S13 Silvia 240SX (89-94) BC Racing BR coilover kit 6/4 kg/mm
The BC Racing BR coilover kit S13 (part number D-12-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the Nissan Silvia, 180SX, 200SX and 240SX on the S13 platform, model years 1989 to 1994. The spring rate is 6 kg/mm front and 4 kg/mm rear.
It is the logical first step for anyone who wants to make their S13 tighter and lower without sacrificing usability. The BR series is BC Racing’s all-rounder: made for daily driving, with enough in reserve for a track day or autocross in between.
An S13 on the original suspension leans heavily in corners and dives under hard braking. With this kit the car sits more calmly on its wheels and you can feel better what the rear axle is doing. You notice that on the road, but certainly also when you go on track for the first time.
The spring rate is 6/4 kg/mm, you adjust the damping in 30 clicks and you set the ride height completely independently of the spring preload. According to BC Racing, the kit also fits the A31.
Key benefits
- All-round setup: comfortable enough for every day, firm enough for a track day.
- 30-click damping adjustment: compression and rebound in one knob, quick to adjust.
- Fully adjustable ride height: independent of the spring preload, so you keep your damper stroke.
- Monotube dampers with linear piston: predictable and linear behaviour.
- Pillowball top mounts at the front: direct steering via the pillowball top mount or camber plate at the front; rubber or original top mounts at the rear.
- Patented concave lock ring: the lower ring stays in place better.
- Spring rate 6/4 kg/mm: a good basis for the light S13.
- Rebuildable: the kit can be rebuilt, so you can enjoy it for a long time.

Fitting and delivery
The kit replaces the original struts and dampers all round. We recommend having it fitted by an experienced mechanic. After fitting and setting the ride height, always have the wheel alignment checked, because camber and toe change as well. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If the kit is temporarily out of stock, you can still order and we will keep you informed of the delivery date.
An S13 that you drive every day and take on track on Saturday does not need a race damper but an honest all-rounder.
Why choose this BR coilover kit S13?
Because you can do everything with it without having to rebuild the suspension for every drive. You set the car at the height you want, turn the damping a few clicks firmer for the track and softer again for the way home. For most S13 drivers, that is exactly the balance they are looking for.

Frequently asked questions
What is the difference between the BC Racing BR and DS for the Nissan S13?
The DS uses the same basis as the BR, but with a digressive piston that responds more tightly to slow body movements. It is more track-focused. The BR has a linear piston and is the better choice if the car is mainly driven on the road.
Is the BC Racing BR coilover kit S13 suitable for a Nissan 180SX?
Yes. The BR coilover kit S13 is intended for the Silvia, 180SX, 200SX and 240SX on the S13 platform from 1989 to 1994, and according to BC Racing it also fits the A31.
Can I drive daily with the BC Racing BR coilover kit for the Nissan S13?
Certainly. With the damping in a softer setting and a reasonable ride height, the BR is perfectly usable as daily suspension.
