well, when i get my Z, im planning on putting around 1400-1500$ into suspension right off the bat, works steeler triple rates up front, with krypton +2 a-arms, and a works duracross in the back, , the a-arms and shocks come in a kit from some suspension company in dirtwheels, for like 950$ u get the a-arms, front shocks, and steel braided brake lines....
then the works duracross bake shock is like 460$
i think the tcs front suspensions are about the same as ohlins ($725+)
if i had the cash id definetly get ohlins....or elka....
