ST XTA Plus 3 Coilover Kit 08-13 BMW 1 Series E82 Coupe 128i /135i

This ST XTA Plus 3 coilover kit includes everything you need to significantly upgrade the suspension on your 2008-2013 BMW 128i or 135i. You get the complete set of four coilovers, featuring advanced KW dampers, linear race springs, and aluminum unibal top mounts. These components work together to give you precise control over your car's handling, whether you're on the street or hitting the track.

Built by hand at KW in Germany, these coilovers are designed for maximum performance and adjustability. The dampers offer 24 clicks of adjustment for both high-speed and low-speed compression, plus 18 clicks for rebound. This allows you to fine-tune your suspension to match your driving style or track conditions. The ride height is easily adjusted using a seamless thread on the galvanized strut housing, even with the kit installed. The composite spring perches are made from a wear-resistant, friction-optimized polyamide with a stainless-steel insert, preventing oxidation and ensuring strength.

The aluminum unibal top mounts help improve steering response and feedback, and allow for camber adjustments when applicable. Each damper is tested on a shock dyno before being boxed to ensure it meets proper force specifications. The galvanized steel housing offers improved resistance to corrosion, and the elastomer bump stops include an integrated dust protection system to keep dirt and water away from the piston rod and seals.
