Product Details

The Function and Form Type 4 Coilovers for the 2013-2020 BMW 4 Series (F32/F34/F36) are the brand's premium coilover system, built around an inverted monotube damper for OE-plus refinement and high-end ride control. Engineered to give your BMW 4 Series a planted, composed feel, these 4 Series coilovers combine a clean lowered stance with the smooth, controlled damping that makes the 4 Series F32/F34/F36 feel composed on any road.

Also branded Function & Form / F2 Suspension, the Type 4 uses a large inverted piston and long-stroke design to add travel, cut unsprung weight, and keep damping consistent when you drive hard. One-way adjustable rebound and compression plus full ride-height adjustment let you tailor exactly how the F32/F34/F36 4 Series sits and responds, in a bolt-on, preload-ready kit. Backed by a 24-month warranty with free U.S. shipping on orders over $250.
