BMW 335i CROSS Competition coilover systems for the High Performance BMW. The Competition Series for the BMW 335i is our top of the line coilover system. It features a lightweight design with a 15 way dampening adjustable monotube damper. With its high strength and durability, the Competition Series insures that it will last through any type of driving condition. The front damper features a 40 mm piston and the rear has either a 40 or 45mm piston depending on application. The ride height adjustability is independent from the spring perch so adjusting ride height does not compromise the spring rate or rebound and compression of the damper. All coilover systems come with a cool bend linear spring that offer last precision steering and handling. Spring rates are also custom tailored to each system and driver's preference. All Competition Series coilovers include front camber adjustable pillow ball upper mounts and most rear includes pillow ball mounts depending on application. Larger luxury vehicles have a softer damper for a sporty luxury feel and also allowing a lower ride height. Based off of racing technology, the Competition Series Coilover is a street performance suspension, customizable for full track use.
