I'm Running new leaf springs.
1 extra leaf, 1 anti tramp leaf. Reversed eyes to keep the camber (and rate) in the spring.
VN wagon short stroke shocks.
No rear sway bar (wagons never got them)
Coupled with KE36/38 and late 55 22mm swaybar, XT130 struts, TA22 GT inserts, 4.5kg springs and camber/castor tops in the front.
Even without a rear swaybar, body roll is minimal (keep in mind its a wagon too).
Had a few people comment on how well it handles.
Not too stiff for everyday driving either.
Hope it helps.
