Street Basis Z Coilover Kit

The TEIN Street Basis Z coilover kit provides a reliable, height-adjustable suspension solution for 2005-2010 Scion tC vehicles. Featuring a twin-tube internal design and steel construction, these coilovers offer an entry-level performance upgrade that allows for precise ride height adjustment via TEIN's ZT-coated threaded sleeves. The system is engineered with shortened shell cases to ensure optimum damper stroke even at lower ride heights. Each kit includes four coilovers, four no-sag springs, and necessary hardware such as bump stops and Delrin thrust washers. This setup requires the reuse of your vehicle's OEM upper mounts, which are not included in the package. The dampers feature fixed, non-adjustable settings tuned specifically to complement the included spring rates (336 lb front and 504 lb rear), eliminating the complexity of matching aftermarket components. Fitment is strictly limited to 2005-2010 Scion tC models. As a height-adjustable system, it allows users to fine-tune the stance of the vehicle while correcting side-to-side height imbalances. The kit includes a 12-month limited warranty and is designed for users seeking a sports-oriented suspension feel with an aggressive stance without sacrificing everyday driveability.
