Dial In Your 87-92 Toyota Supra (MA70L) Turbo Ride and Handling
The Tein Street Advance Z coilover kit (GSL44-9USS2) gives 87-92 Toyota Supra (MA70L) Turbo owners a full-length adjustable suspension platform built around a twin-tube damper for a comfortable ride that still tightens up when the road gets twisty. Uses the vehicle's OE upper mounts (not included). Twin-tube damper system delivers a longer stroke and smaller repulsive force for high ride comfort, smooth low-speed behavior, and stable high-speed control. Ride height is adjustable via the lower spring seat. A sealed structure (narrowed shell pipe top, oil/gas injected, crimped seal) keeps cost efficient without sacrificing quality. An optimal dust boot protects the piston rod (some vehicles use OE dust boots). Street Advance Z adds a damping force adjustment dial so the driver can fine-tune compression and rebound feel for the road or track.

About Tein
Tein has engineered coilover suspension in Japan for decades, and the GSL44-9USS2 Street Advance Z continues that lineage with a sealed, cost-efficient damper platform that does not compromise on ride quality or durability. The No-Sag Spring is cold-formed from SAE9254 steel with a minimum tensile strength of 200 kgf/mm2, resisting sag over time. Its durable powder coating resists peeling and flaking. The high-performance damper oil holds a stable viscosity across temperature ranges, resists foaming and cavitation, and tolerates heat, making it well suited for spirited street driving. TEIN-Green powder coating uses a patented two-layer, one-bake method (Japanese patent 4347712) with no harmful solvents. ZTP coating on the ride-height adjustment thread resists abrasion and corrosion to help prevent rust-seizure. Tein backs its coilovers with manufacturer-supported quality standards.
