Specifications

• Coverage: Front & Rear (complete vehicle set — 4 units)
• Type: Coilover
• Height Adjustment: Yes — vehicle-height adjustable

Performance

Street Advance Z is a coilover tuned toward comfort. Height and 16-step damping are both adjustable, but the baseline valving is deliberately softer than Tein's sport kits, so the car stays civil on broken surfaces and long drives. Built for daily use first, with the adjustment there when you want to firm it up.

Fitment

Fits 4 BMW models including 1er (E87) and 3er Touring (E91) — see the full list below. Verify fitment using the vehicle compatibility checker above.

What's Included

One complete Tein Street Advance Z kit — four units, front and rear, for the whole vehicle. Threaded bodies and adjustment collars are part of the kit. Springs, top mounts and fixings are not included unless the specification table lists them.

Warranty

Backed by Tein's manufacturer warranty against defects in materials and workmanship. Cover assumes the kit is installed as a complete set and set up within the ride-height and damping range Tein publishes for it — running a coilover outside its tested height range is the usual reason a claim fails, so keep the setup inside the manual's figures and have the alignment checked afterwards.

Notes

Data applies to sport suspension model. Use of oe-equivalent size wheel is recommended, as there may not be enough clearance around the front shock absorber.
