ST 132100AP Coilover Kit ST X AUDI A4 (B9); (B8, B81) 10/15-

ST 132100AP Coilovers ST X galvanized steel (with fixed damping)

The ST suspensions X coilovers are designed to provide adjustable ride height and improved handling characteristics while maintaining reliable daily usability. Developed in cooperation with KW Automotive, the system features a threaded body design that allows continuous lowering adjustment within the tested range, depending on the specific vehicle application.

Ride height adjustment is performed via a polyamide adjustment ring on a galvanized strut with multiple sealing layers, ensuring durability and resistance to environmental influences. Typical lowering ranges vary by platform, with many applications offering approximately 35–65 mm reduction, while factory-lowered vehicles may have a reduced adjustment range.

The twin-tube dampers are engineered with low-friction internal components and pressure-resistant housings, combined with a chrome-plated piston rod for long-term performance. A mono block guide and sealing package protect the system from contamination, ensuring consistent damping behavior and reliability in all weather conditions.
