Am Looking at purchasing some new springs for my Suzuki Escudo Nomade 1992 LWB (5door) for a 40mm lift and was wondering where others had purchased there's from?
My understanding is that you can run factory shocks without issue with a 40mm lift.
Also is it common to change camber bolts as well?

Chamberlain suspension in CHCH. $400 for a set 50mm lift springs. Standard shocks will do but extending them and removing the front sway bar helps heaps.
