Did you remove the load from the front wheels (jack front wheels of ground) before trying to tighten them up. To adjust ride height, you adjust the tenion on the torsion bars, but only after jacking cau up off the ground first, or you will damage bolts.

Don't want to be a spoil sport - but winding up the bars solves the clearance problem but does two bad things.

Bad Thing 1 - Increases spring rate - makes ride harsh and limits travel

Bad Thing 2 - Removes suspension droop travel, all bump - no droop.

Body lift is a better solution, a little more difficult but makes the most of
the limited travel available.

Adjusting the bars is quick and nasty.

Do a bodylift and if you still have to wind up your torsion bars, then do it the absolute minimum. Mine are cranked to the max at the moment to fit 31's, but as soon as I get my bodylift done, they'll be coming back down. Rides like shit at the moment. Only reason I put up with it is that it's not my DD anymore.

Incorrect. Your spring rate stays exactly the same, the torsion bar keeps it's same spring rate regardless of which level your suspension is set to.

What it does do is changes the neutral position of the suspension and it's geometry once a wheel allignment is done. This is what gives the harsher feel.

Actually it most likely isn't as there are rules on the ratio of up travel vs down travel in ADR's when making suspension height mods. ;)

1" of torsion bar winding would be more legal than 1" bodylift for example.

My insurance wouldn't care about torsion lift... but body lift would render me uninsured.

Techincally they would Nick, as it is a deviation from factory spec of the vehicle.

Differences of opinion - great !

Well in Vic there are rules govening the raising or lowering of the suspension " the clearance between a suspension component and its bump stop is not altered by more tha 1/3 of that specified by the manufacturer" - and on Feroza's that gives you nothing to play with - especially if your going for larger wheels and tyres.

So winding up the bars to fit bigger tyres ( which in itself can be illegal )
can make the vehicle unroadworth and would obviously be an insurance issue.

And on the bar stiffness issue, I didn't explain myself well ( glossed over
the details - sorry )

When you crank up the bars you change the angle of the lower suspension arm ( it points down and so has a different wheel travel to torsion bar ratio ( its a geometrical thing apparently ) and so the package is effecively stiffer. At least this is what my research is telling me - and
its a bit off a brain twister.

There are also relationships between the position and rate of the bump stops on torsion bar equipped vehicles - bars are linear rate and rely on
the bump stop to create an overall rising rate to the suspension - whereas coils can be made rising rate by design. Its a fact that seems overlooked
frequently - bump stops do more than stop bumps !

As for body lift - i can't find the actual rules controlling it so I can't
really say if its legal or not an/or by how much. But i don't think they
are specifically illegal.
