What is the primary benefit of the composite spring perch?

The composite spring perch is made from a wear-resistant, friction-optimized polyamide composite with an embedded stainless-steel insert. This design prevents oxidation and corrosion between the strut and perch, ensuring that ride height adjustments remain easy and effective over time.

How is the ride height adjusted with this kit?

The kit features a seamless ride height adjustment system. The unique trapezoidal thread pitch on the galvanized steel housing, combined with the composite spring perch, makes it straightforward to dial in your preferred ride height.

About this part

Product Details

This ST X Coilover kit is built for BMW 3 Series F30 AWD sedans from 2013-2018 and 4 Series F32 AWD coupes from 2014-2020. It's designed to give you that sporty stance and improved handling you're looking for, without sacrificing too much comfort for daily driving. You can easily adjust the ride height to get the exact look you want, whether you're aiming for a subtle drop or something more aggressive, and it helps you dial in your tire and wheel fitment perfectly.

The engineers at ST Suspensions, drawing on expertise from KW, have tuned the dampers and spring rates specifically for each vehicle application. This means you get a well-balanced setup that works with your car's dynamics. The spring perches are made from a durable, friction-optimized polyamide composite with a stainless steel insert. This combination prevents corrosion between the strut and perch, ensuring that adjusting the ride height remains smooth and easy for the life of the kit. The galvanized steel struts offer solid protection against corrosion, and a built-in dust protection system keeps dirt and debris away from the piston rod and seals, helping to maintain the damper's performance over time.

These coilovers are assembled by hand by experts at KW in Germany, and each damper is tested on a shock dyno to confirm it's producing the correct forces before it's boxed up. This attention to detail ensures you're getting a well-built suspension system. You'll also find an elastomer bump stop with integrated dust protection, which acts as a dynamic load limiter while helping to preserve ride quality and durability. This kit is a great way to get a significant upgrade in both the look and feel of your BMW's suspension.
