TEIN S.TECH Kit for Subaru Legacy BL9

This model-specific spring kit lowers the ride height of the fourth-generation 2.5-liter Subaru Legacy sedan (BL9 chassis) to improve its center of gravity. This reduction in height results in reduced body roll and noticeably sharper cornering and steering response.

For the Subaru Legacy BL9, the TEIN S.TECH springs typically lower the front of the vehicle by approximately 1.2 inches and the rear by about 1.0 inch. The exact drop specification is engineered specifically to improve the aesthetics and handling of the fourth-gen suspension without being excessively low.

While not strictly required, TEIN S.TECH springs are designed to work best with high-quality aftermarket performance shocks like Bilstein or KYB. Factory shocks are usually tuned for standard spring rates and may experience accelerated wear or a harsher ride when paired with shorter, stiffer lowering springs.

The S.TECH line is engineered to offer an excellent balance between improved track-like performance and comfortable daily drivability. They use a progressive spring rate design that maintains reasonable ride quality on rough city streets while stiffening up during aggressive cornering.
