Product Description

The TEIN Street Basis Z Coilover Kit (GSB48-81SS2) is engineered to deliver an affordable yet high-quality suspension upgrade for the Acura TSX and Honda Accord CL-series platforms. Featuring TEIN's twin-tube damper design, the system provides improved ride comfort and stability compared to factory suspension while maintaining excellent durability for daily driving. The sealed damper construction also enhances reliability and reduces manufacturing cost without sacrificing performance.

This kit includes high-tensile performance springs and a threaded spring seat design that allows ride height adjustment to achieve a lower and more aggressive stance. Typical drop ranges can reach approximately 34-122 mm (1.3-4.8 inches) in the front and 20-75 mm (0.8-3.0 inches) in the rear depending on setup and vehicle configuration. Designed to reuse factory upper mounts, the system offers straightforward installation and is ideal for enthusiasts seeking improved handling and adjustability while maintaining daily-driving comfort. Fitment is confirmed for CL7 and CL9 chassis vehicles with FWD drivetrains.
