COILOVERS BR / BC RACING / PORSCHE CAYMAN/BOXTER 987

BC Racing BR coilovers for Porsche Cayman / Boxster 987

This BC Racing BR coilover kit suits Porsche Cayman and Boxster type 987. Balancing performance, precision and versatility, it suits demanding road drivers and track-outing or trackday enthusiasts.

Drawing on BC Racing’s motorsport experience, these coilovers improve dynamic handling with an adjustable, reliable solution suited to regular use. Spring rates are always stated as Front / Rear.

Purpose of the part

Coilovers replace original dampers and springs to control body movement, height and firmness better. They are essential to handling, braking stability, corner-entry precision and corner-exit traction.

The BC Racing threaded body adjusts height through the lower damper mount without changing spring preload or unnecessarily reducing travel. It provides effective, controlled adjustment for sporty roads or a greater track focus.
