CUSCO is a Japanese automotive parts company, specializing in car suspension parts. They're most famous for their coilover suspensions, and are a large presence in the Japanese after-market automotive scene both in Japan, and in the JDM scene around the globe. A notable product of CUSCO is the "E-CON", a coilover suspension set with electronically controlled dampers. Cusco sponsored a high performance, RWD mid engined 2 door version of the Subaru WRX STI for professional racing. *note cusco was a player in the development of many jap race cars including nissan's during the 90's. So the product is definitely good, but as mentioned, you have to decide which spring rates, etc you are going to want to run, for either street use or track. then make a choice on which specific coil over you shall wish to use.
cusco coilovers are definately worth considering but most of zero/zero2 models to suit z32 have like 12/10 spring rates which is way more than you want on aussie roads.
Cuscos are awesome. I have a set on my zed. 9kg fronts, 6kg rears. Were for a GTR but shaved a few mm off the front tops and they fit perfect. Awesome ride and not too hard.
They are good, but your car will be unregistered, uninsured and illegal/unroadworthy(check with Omelette Boy).
How would these make my car illegal/unroadworthy compared to any other type of shocks? as long as height stays legal :/ ?
