I have recently installed coilovers on my fiance's 04 cavy and not sure i used all the pieces correctly i had no instructions to follow but of course it looked easy enough the only pieces i had left over were a sack of o rings i don't no what to do with them if anybody can maybe give me a few pointers i take off and start all over again if necessary or if anybody knows who makes DZ coilovers i have tried looking up dropzone.com
