Show original supplier description
This kit offers full-length ride height adjustability, allowing for precise customization of your vehicle's profile without sacrificing suspension stroke. The damping force is also adjustable, enabling drivers to fine-tune the ride stiffness to their preference, whether for daily driving or more spirited use. Constructed with Tein's commitment to quality, these coilovers are manufactured and assembled in their Yokohama, Japan factory. The Street Basis Z series utilizes OE-style shape and includes upper mounts for straightforward installation. Specific spring rates are provided for optimal performance: 280 lbs/in (5.0 kg/mm) for the front and 336 lbs/in (6.0 kg/mm) for the rear. The front springs have a free length of 175mm with an inner diameter of 70mm, while the rear springs are 250mm with a 70mm inner diameter. The ride height can be adjusted by -1.2 inches in the front and -1.2 inches in the rear, with an adjustable range of -2.7 to -1.0 inches for the front and -3.0 to -0.2 inches for the rear. It is crucial to note that exceeding the recommended ride height adjustable range may lead to clearance or interference issues and could void the product warranty. This kit is specifically designed for the 2008-2014 Subaru WRX models.
