BMW E46 M3 Convertible (00-06) BC Racing BR coilover kit 6/9 kg/mm

The BC Racing BR coilover kit E46 M3 Convertible (part number I-121-BR-RA) is a coilover kit adjustable in height and damping, also simply called a coilover, for the BMW E46 M3 Convertible, model years 2000 to 2006. The spring rate is 6 kg/mm front and 9 kg/mm rear.

It is the all-round BC Racing kit for the open-top M3. BC Racing supplies its own part number for the Convertible, separate from the Coupe, so the kit matches this version of the M3.

The BR series is intended for daily driving with the occasional track day or autocross. You get monotube dampers with a linear piston and 30-click adjustment, with compression and rebound adjusted together. The spring rate is 6/9 kg/mm front/rear.

You set the ride height fully via the damper body, independently of the spring preload. This lets you put the Convertible at the desired height without the damper losing stroke. The patented concave lower lock ring locks that setting in place.

Key benefits

Fitting and delivery

You drive an M3 Convertible for the enjoyment: the BR makes it firmer and lower without taking away the enjoyment on the road.

Why choose this BR coilover kit E46 M3 Convertible?

Because the original suspension of an older M3 Convertible is often tired and lets the car move more than necessary. With the BR you get a new, adjustable suspension that suits the open-top M3 and that you tune yourself to the way you drive. A logical choice if you mainly use the car on the road.

Frequently asked questions

Why is there a separate BC Racing BR coilover kit for the BMW E46 M3 Convertible?

There is a separate kit because BC Racing uses its own part number for the M3 Convertible, I-121-BR-RA. So order this BR coilover kit E46 M3 Convertible and not the Coupe version I-14-BR-RA.

What is the difference between the BC Racing BR and DS for the E46 M3 Convertible?

The DS has a digressive piston that damps more firmly at slow movements and is more track-focused. The BR is the all-rounder with a linear piston.

What is the delivery time of this BC Racing BR coilover kit?

The delivery time is usually 1 to 2 weeks as long as the manufacturer has stock. Without stock you can still order and we will keep you informed.
