BC Racing ASP Series For BMW F80/F82 M3/M4 5-Bolt Top Plate (W/ Front Camber)

BC Racing’s new adjustable spring perch (ASP) is an excellent solution for customers seeking a lowered stance, but still require the OEM electronic damping system to remain functional. Compared with conventional lowering springs, the BC Racing ASP offers ride height adjustability that seamlessly allows users more flexibility to tailor their chassis to the needs of modern suspension, performance and style.

The vehicle specific custom springs used in the ASP kit are designed to work optimally with carefully calculated OEM damper travel lengths, specifically for lowered ride heights. This package allows you to enjoy OEM-like ride quality combined with height adjustability and increased chassis stability at higher speeds.

**Please note that custom spring rates, extreme-low specifications, and SWIFT spring upgrades do not apply to the ASP product line.
