Product Description

The TEIN Street Basis Z Coilover Kit (Part No. GSQ54-8USS2) is an entry-level, height-adjustable suspension upgrade built for the 2013-2024 RWD sport coupe and sports car platforms including the Scion FR-S, Subaru BRZ, and Toyota 86/GR86. Designed to strike a balance between daily comfort and improved road handling, this coilover set provides significant lowering capability while maintaining compliant ride quality on varied road surfaces. The twin-tube damper architecture and no-sag springs work together to deliver a confident feel on street driving and spirited cornering.

Ride height adjustment is achieved via TEIN's ZT-coated threaded spring seats, allowing you to dial in your desired stance and lower your vehicle up to approximately 2.7" (front) and 3.0" (rear). While damping is fixed (non-adjustable) and tuned for street use, the kit's corrosion-resistant construction and robust dust protection help ensure long-term performance. OEM upper mount reuse simplifies installation, and the balanced spring rates make this coilover set ideal for enthusiasts who want a more aggressive look and enhanced handling without sacrificing everyday ride comfort.
