Tein Basis Coilovers Subaru WRX 2002-2007 / STI 2004

Add to Wishlist


Tein's Basis coilovers for the WRX and STi are an entry-level setup that features ride-height adjustment but does not offer adjustable shock damping. Basis setups are valved for street use and are essentially an affordable, balanced solution to purchasing shocks and springs or sleeve-type coilovers. They feature a steel twin-tube design, with adjustable spring perches and utilize the OEM suspension mounts. Because the Tein Basis coilovers are a complete setup, they offer increased stroke over a stock-type setup or spring and shock package, which increases shock life and prevents the 'bottoming out' traditionally associated with lowering springs. This kit is rebuildable, making it a long-term solution.

Years of use

, Jun 1, 2010
I've had these on my car for the last two and a half years. I recently took them off to send to Tein to have them rebuilt. I love these coilovers, usually. The car handles amazing, ride quality is good most of the time. However, coming from MN, expansion joints cause massive amounts of bouncing, as do certain road services. Small price to pay for phenomenal handling, but still annoying at times. Perfect for canyon carving, auto x, spirited driving, not great for road trips.
