Tein Street Advance Z Coilover Suspension Kit for MINI One & Cooper R50 RA16 (2002-2007) - Height Adjustable 16-Stage Dampers Lowering Kit | BMW MINI Mk1 Hatch Fast Road Adjustable Shocks

Street-focused height adjustable suspension for Mini One and Cooper 2002 to 2007

Upgrade your Mk1 MINI handling with this Tein Street Advance Z coilover kit, engineered for the Mini Hatch platform and perfect for fast road driving, daily use and a purposeful stance. Expect taut body control, sharper turn-in and a confident, composed ride on British roads thanks to a compliant twin-tube layout and a wide adjustment window that lets you dial in comfort or firmness in seconds.

Built as the latest evolution of Tein’s respected Super Street line, Street Advance Z brings a shorter case design to maintain usable stroke at lowered ride heights, plus a ZT coated threaded sleeve for smooth, precise ride height changes and strong resistance to corrosion. Tein’s Advance Needle technology delivers a far more noticeable change in damping force through each click, so you can fine tune your MINI for city commutes, B-road blasts or show-ready stance without compromise.
