You ultimately and usually get what you pay for here and O.S.
On the odd occasion when you do get ripped off at least if you bought in Australia you have recourse or can go bash somebody!
Back on topic - shocks n springs for BC, K-sport, etc coilovers are all around 1200-1300 in Australia. Sorry but saving a $100 bucks wouldn't make me buy from O.S.
Serious about handling then save/spend $3500 and do it all and properly.
