You probably don't need to get cartridge units for your forks mate. Springs were like 250, full overhaul was about 200, gold valves we're about 240. I can look up the invoice if you like.
Who were you speaking too, if I can ask ,?
Boxa have a look the Ohlins STX36 shocks, I paid $1300 for the set here in Aus.
Don’t forget about the Fournales shocks.
