BMW Z3 (96-02) BC Racing BR coilover kit 5/8 kg/mm

The BC Racing BR coilover kit Z3 (part number I-10-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW Z3 with rear-wheel drive, including the Z3 M, model years 1996 to 2002. The spring rate is 5 kg/mm front and 8 kg/mm rear. When ordering, you choose the version for central or offset top mounts.

BC Racing supplies this BR kit under the same part number in two versions: one for the Z3 with the original central top mounts and one for the Z3 that has offset top mounts from the factory. With a central top mount the damper rod sits in the middle, with an offset top mount it sits off-centre. So it pays to check first which top mount is fitted to your car.

With the BR you choose BC Racing’s all-round line, made for a car that is driven a lot on the road and occasionally comes along to a track day or autocross. The monotube dampers with a linear piston respond predictably, you adjust the damping in 30 clicks and you set the ride height via the damper body, independent of the spring preload.

Key benefits

• Central or offset top mounts: you choose the BR version that matches the original top mounts of your Z3 or Z3 M.
• Height via the damper body: lowering without changing the spring preload.
• Damping in 30 steps: compression and rebound together, adjustable per corner.
• Linear piston: calm and predictable behaviour on the road.
• Spring rate 5/8 kg/mm: the springs BC Racing uses for the BR on the Z3.
• Pillowball top mounts or camber plates at the front: rubber or the original mounting at the rear.
• Concave lower lock ring: patented BC Racing design that locks the height setting.
• Can be rebuilt: the dampers are rebuildable.

Fitting and delivery

Before ordering, check whether your Z3 has central or offset top mounts and choose the matching version. The coilover kit is vehicle-specific and takes the place of the original dampers and springs. We recommend having it fitted by an experienced mechanic. On some cars the pillowball top mount at the front requires a small modification to the upper mounting; if in doubt, contact us. Setting the ride height should be followed by a wheel alignment, because the wheel geometry changes as well. The delivery time is 1 to 2 weeks as long as the manufacturer has stock. If BC Racing temporarily has the kit out of stock, you can still order; we will keep you informed of the delivery date.

For a BMW Z3 with original central or offset top mounts, the BC Racing BR with part number I-10-BR-RA is the all-round kit for the road and the occasional track day.

Why choose this BR coilover kit Z3?

The Z3 is a compact car with rear-wheel drive that gives a lot of driving pleasure on well set-up suspension. With this BR kit you choose the height and damping yourself, so the car turns in more sharply and rolls less, while remaining comfortable for everyday driving. If you choose the version that matches your top mounts when ordering, central or offset, you have the kit that BC Racing UK lists for your Z3.

Frequently asked questions

Which version of the BC Racing BR coilover kit do I need for my BMW Z3: central or offset top mounts?

That depends on the original top mounts in your Z3 or Z3 M. With a central top mount the damper rod sits in the middle; if it sits off-centre, you have offset top mounts. At BC Racing, both versions have the same part number I-10-BR-RA, and you choose the right one when ordering. If in doubt, send us a photo of the top mount or your chassis number and we will find out for you.

Does the BC Racing BR coilover kit for the Z3 also fit a Z3 M?

Yes. BC Racing UK lists both versions for the Z3 with rear-wheel drive from 1996 to 2002, including the Z3 M. Choose the version that matches the original central or offset top mounts of the car.

What is the difference between the BC Racing BR and DS for the BMW Z3?

The BR coilover kit Z3 works with a linear piston and is intended for the road with the occasional track day; the DS has a digressive piston that damps more firmly at slow movements and is more focused on the track. Both have 30 clicks and, for the Z3, a spring rate of 5/8 kg/mm. BC Racing UK only lists the DS for the Z3 in the version with central top mounts; if you have offset top mounts and want a DS, please contact us first.

How long is the delivery time of the BC Racing BR for the Z3?

1 to 2 weeks for both versions, as long as the manufacturer has stock. If BC Racing temporarily does not have it, you can still order and we will tell you the expected delivery date.
