Overview

This kit features gas-injected, twin-tube struts and includes no-sag springs.
Show original supplier description
The TEIN Street Basis Z Coilover Kit is engineered to enhance the handling and stance of compatible Subaru Impreza WRX STI models from 2008-2014. This cost-effective coilover system allows for ride height adjustment via the spring seats, offering a more efficient way to achieve a desired look compared to lowering springs and stock struts. The kit features no-sag springs and is powder-coated in TEIN's flagship green, complemented by a special surface ZT coating for durability. This kit offers a ride height adjustment range of -1.4 inches at the front (with an adjustable range of -2.8 to -0.9 inches) and -1.2 inches at the rear (with an adjustable range of -3.0 to -0.2 inches). Front spring rates are 392 lbs/in (7.0 Kg/mm), and rear spring rates are 280 lbs/in (5.0 Kg/mm). It is important to note that exceeding the recommended ride height adjustment range may lead to clearance issues and could void the product warranty. The Dampening Force is listed as not adjustable.
