KSport Kontrol Sport Coilovers - 2014-2018 BMW 4 Series Coupe 428i, 430i, 435i, 440i Excl. M-Technik, xDrive and EDC (F32)

KSport's Kontrol Sport Fully Adjustable Coilover Kits have 20-30% stiffer spring rates and shock damping compared to our Kontrol Pro coilovers. Our Kontrol Sport system is intended for people that would prefer a slightly stiffer set up than our Kontrol Pro system.

36 levels of damping adjustment allow fine tuning of the damper to suit both handling and comfort needs. The damping adjustment alters compression and rebound simultaneously, for more effective and user-friendly setup changes. Pillow ball top mounts in the front and rear on some applications allow the vehicle to install and setup to OEM specifications.

KSport's patented upper pillow ball mount offers the same level of adjustability and performance, but allows for compliance that is often required from high-demand strut applications. On applicable models, the pillowball upper mounts offer camber adjustment, saving the need for a special, separate camber kit.

For enthusiasts seeking the ultimate in adjustability, KSport's advanced upper pillow ball mount is available on some applications, giving the option for separate camber and caster adjustment. Most applications utilize an adjustable lower mount, which means height adjustability without losing suspension the travel problem found in many coilover systems available today. Since mounts and most pieces in the coilover system are designed from 6061 billet aluminum, the components are lightweight, durable, and rust resistant.

Steel shock bodies are electroplated with zinc to resist rust and protect from the elements. The shock or strut valving for each piece is matched accordingly to the spring rate, giving superior ride quality and reliability.

The KSport system uses a Monotube design in which the oil and gas are separated within the cylinder. When compared to twin tube construction, the Monotube design dissipates heat faster and more evenly, allows finer damping adjustments, and requires more expensive design process. Aeration and cavitation issues are a lot less common in a Monotube design, which results in a more consistent ride quality.
