BC RACING COILOVERS DS SERIES - BMW X3 E83 03-10 (AWD)The BC Racing DS Series is built around digressive valving, offering similar benefits to the BR Series but with a stronger focus on track performance. The digressive piston design delivers a non linear damping curve, allowing higher low speed damping to control body roll during cornering, braking, and acceleration, while reducing high speed damping to let the suspension travel freely over kerbs and rough sections without unsettling the chassis. Key

Combines highly refined mineral oil (preferred for engine break-in) with an advanced additive package containing elevated levels of zinc/phosphorus anti-wear additive to optimize wear protection during the sensitive engine break-in phase

gains of between 7-15bhp and a lot more torque are easily achieved

it’s worth replacing the air filter element itself periodically

the comprehensive kit also includes a replacement aluminium intake pipe

Various Alcon Big Brake Calipers (see brake pad diagram image)

8D ABS (1989-1995) are precision-built in-house

The inner and outer tubes are bonded to the rubber section to a strength of over 1000psi then stress-relieved so that all forces are distributed throughout the bonded area

Failures of the mounts and brackets cracking are common problems
