The primary issue with premium suspension upgrades is that these components mount in the same locations as the factory units, and utilize the same control arm designs.

Suspension Reinforcement components are parts that work alongside your upgraded or factory suspension to triangulate suspension geometry more precisely.

The ECS Rear Trailing Arm Bushing Limiter more exactly specifies the range of motion of your trailing arms, while Heavy Duty Rear Shock Mount Reinforcement Plates provide better rear suspension response while eliminating the possibility of rear shock blowout.

One of the obvious benefits to owning a turbocharged car is the ability to realize significant power gains simply by altering boost pressure.

AFE has gained a deep understanding of airflow engineering through their experience manufacturing premium air filter elements and air intake systems. Their latest release, the Scorcher Power Module for the BMW F30 335i, is the ultimate expression of the company's mastery of air induction science.

Control over camber and caster is critical to achieving the perfect stance and handling characteristics. Whenever your ride height is lowered, the new geometry specified by the control arms introduces negative camber and caster, compromising your tire's contact patch and altering wheel fitment.

SPC Front Adjustable Camber Plates and Bushings give the discerning BMW E9X owner the control over suspension dynamics that makes an already good handling car great. With a wide range of caster and camber adjustability, the new-found level of handling tunability is a welcomed addition.
