WTF are Build Bux?
Part #: DSA64-6USS4

Flex coilovers are designed to provide the ultimate balance between sporty comfort and performance for your Acura TSX. They are a completely different coilover from the Street line, utilizing a fully threaded shock body that is adjustable both at the spring perch and lower shock body for independent height and spring preload adjustments. The twin-tube damper design makes for improved reliability and longevity. These are Tein's street/competition coilovers; they can be tuned for street use but will also be at home on the racetrack or autocross course. Tein Flex coilovers include upper mounts and are also fully rebuildable, making them a complete long-term solution.
