Function and Form Type 4 Coilovers for 2004-2009 Mazda 3 (BK)

The Function and Form Type 4 Coilovers for the 2004-2009 Mazda 3 (BK) 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 Mazda 3 a planted, composed feel, these 3 coilovers combine a clean lowered stance with the smooth, controlled damping that makes the 3 BK 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 BK 3 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.
