This is a set of Type-E Coilovers with Pillowball Upper Mounts for the EK4 / EK9 Honda Civic from high-end suspension specialist, Aragosta.
Aragosta’s Type-E series of dampers are designed with both spirited street driving and comfortable cruising in mind. The Type-E includes several of high tech features of their Type-S and Type-SS high performance coilovers, including low-friction, WPC-treated inverted struts, height-adjustable Rana springs, specially formulated synthetic damper fluid and Aragosta’s unique low friction seals. Additionally, the Type-E features 12-step rebound adjustment knobs (not available for some vehicles) on the bottom of each damper, as well as pillowball upper mounts (camber adjustable mounts available for some applications).
