BMW Z3 M E40 Aragosta Suspension Kit – Type-S Coilovers with Pillowball Upper Mounts
This is a set of Type-S Coilovers with Pillowball Upper Mounts for the E40 BMW Z4 from high-end suspension specialist, Aragosta.
Aragosta’s Type-S series of dampers are designed with both comfortable street cruising, as well as track-use in mind. The Type-S includes many high tech features, including low-friction, WPC-treated inverted struts, height-adjustable Rana springs, Kashima-coated forged aluminum cylinders, specially formulated synthetic damper fluid and Aragosta’s unique low friction seals. Additionally, the Type-S features 12-step rebound adjustment knobs on the bottom of each damper, as well as pillowball upper mounts.
(Kashima Coat is a special, ultra-low friction anodizing process that infuses molybdenum alloy, providing better corrosion resistance and a smoother surface than standard anodized aluminum. Kashima Coat is especially effective for damper cartridges, as tiny oil molecules can stick to the surface causing it to become even slicker, thus allowing for even smoother operation. Dampers utilizing Kashima Coat are revered for their smoother feel and response over rough and bumpy surfaces both on and off the track.)
