Lifting your Foz doesn't just give more clearance so you can do harder tracks, it also keeps you further away from rocks, etc so you're less likely to damage underneath. No-one wants damage lol
There's a few options to lift a Foz.
1) Raised springs, Kings are most popular, Dobinsons also do them but have a bad reputation for snapping!
Gives about 35mm lift but can be harsh over bumps, potholes and reduces articulation. Increases load carrying capacity, but a lightweight Foz shouldnt really be loaded too much2) 1" strut top spacers like those from Subtle Soluitions, Gorilla or Paranoid, all in the US.
3) 2" spacers like the ones I do. They have both camber offset to give a little more negative camber despite the lift and caster offset to give more positive caster. Subies are lacking in caster, this gives better straightline tracking (reduces tramlining) and improves dynamic camber for better cornering. Gains of ~.5deg neg camber & ~1.2deg caster
Theres no room for camber offset in the rear strut towers so aftermarket camber bolts are needed.
Trailing arm spacers should also be used with any lift over 1" to keep the rear wheel centred and keep the rear suspension geometry as much as possible.
