Springs

Almost every set here is Tein S.Tech, a progressive-rate street spring built to work with the dampers your car already has. The drop is specified per chassis rather than as a single figure across the range, and the progressive rate is chosen so the car sits lower without the harshness of a track spring. A small number of Tein High.Tech and OE-Tech sets are also listed, which sit slightly higher and stay closer to standard ride quality.

Coverage is strongest on Japanese platforms — Toyota, Honda, Subaru, Mazda, Nissan and Lexus make up most of the catalogue — with BMW, Audi, Volkswagen, Mitsubishi and Tesla sets alongside them. Each set is cut for a specific chassis code, so select your car rather than matching on model name alone.

How to choose: fit springs on their own if your dampers are healthy and you mainly want a lower stance. If the dampers are already worn, replacing both together avoids fitting new springs to tired damping. If you would rather set the height yourself, a full coilover such as Tein Flex Z adjusts height and damping together, and the Bilstein B12 kit supplies matched dampers and lowering springs as one package.
