TEIN Street Advance Z4
Lift and Ride Height Adjustment
STREET ADVANCE Z4 uses a thread type ride height adjustment system, where height is set by moving the lower spring seat up or down for a simple and easy setup. Standard ride height is set around 1 inch, roughly 25mm, higher than original, since the damper is specifically designed and tested per vehicle for this lifted position rather than being a standard damper simply raised, which would otherwise reduce rebound stroke and push the camber angle positive on strut suspensions. Damping force is adjustable across 16 levels for compression and rebound together, and the kit is also compatible with TEIN's EDFC range for electronic adjustment from the driver's seat.

Construction and Off Road Durability
STREET ADVANCE Z4 uses a twin tube damper structure for longer stroke and a smaller repulsive force than a mono tube design, giving a comfortable ride across varied and rough surfaces. It also features TEIN's Hydraulic Bump Stopper, which converts the impact of a full stroke into heat rather than letting it escape as a repulsive force, keeping the vehicle stable over big hits and reducing wear on the damper, useful both fully loaded and off road. The shell case is finished with TEIN's green powder coating, patented 2 layer, 1 bake anti rust treatment, and ZTP surface coating for protection against stone chips and corrosion.
