Complete BC Racing BR Coilover Kit for the BMW 3 Series
This BC Racing BR coilover kit provides a complete suspension upgrade for the BMW 3 Series 3 Sedan Convertible E46 1998-2006 RWD Convertible, Saloon/Sedan. The package includes suspension units for all four corners of the vehicle, allowing the original dampers and springs to be replaced with an adjustable system developed for the specific chassis.
BC Racing manufactures suspension for a broad range of road, performance and motorsport applications. Its vehicle-specific approach allows spring specifications, damper settings, mounting points and suspension travel to be selected around the individual model rather than applying a universal setup.
What Comes with the Kit?
Every BC Racing coilover kit covers all four wheels. The exact configuration varies between applications. Some kits include front and rear top mounts, while others require the original mounts to be reused.
Vehicles fitted with original rear leaf springs generally retain that suspension design. BC Racing does not automatically convert these applications to rear coil springs. Where the listed spring specification includes an X, such as 6/X, the figure represents the front spring rate and the X confirms that no replacement rear coil spring is supplied.
End-links are included where a revised anti-roll bar mounting position makes shorter links necessary. Where replacement end-links are not included, the original components can normally continue to be used.
Installation and Setup
Kits are normally supplied with spring preload already set, providing a sensible starting point for installation. Ride height and damping should then be adjusted carefully and evenly.
Professional fitting is recommended, followed by a full wheel alignment after the suspension has settled. Available from Paramount Performance, vehicle tuning and performance specialists since 1986.
