Im going for the slightly different approach of lowering my brumby, Is there any catches I need to look for.... apart from the law? :/

Seen a nice one lowered in photoshop! Have you played with the wind up wind down nut at the top of the beak in the middle of the torsion bar set up yet? Factory clearance of the bump stops is only 20mm so you won't have much to play with. I believe if the torsion bar ends on the outer are disconnected and reset to a different spline you get a different height and needs tinkering with to understand it. Watch out for any energy left in the torsion bar so you'd start with the wheels just hanging off the body with body on stands I'd reckon

Ok, Word from the local suspension shop, The front can be lowered around 30-40mm by using a set of "sports low" king springs from a Ford Capri, As the Capri uses the same springs as a brumby standard.

The back is a case of adjusting the "wind down" bolts on the torsion bar, or as mentioned above rotating the mounting plate on the end of the tortion bar.

The front springs are going to cost $140.00 And should be here in a week or so, depending when the minister of finance (missus) lets me buy them.:cool:

the lower front may give better DOJ life due to lesser nasty angle it has to work at. With the rear and the law. Some states allow a 1/3 reduction so that 20mm can go down to about 14mm

Well The back of mine cant go lower as it is, due to the fact its already running on the bump stops (probably should have stuck my head under their earlier). Would there be a problem if i cut 10-20mm off them?

The of tire to guard clearances on mine are, Front : 75mm, Back 70mm (my other brumby, un-modified I think, sits 110mm front, 125mm back . But I would like my new one just that little bit lower or less tire to guard clearance. Maybe bigger rims might make it better :/

i used to get my coil springs reset at local spring works, strip struts for em, and tell them how much lower you want them, used to be $40 prob $100 now tho

I thought I would get this going again instead of starting a new thread. Does anyone have pictures of a brumby lowered, with springs and wound down rear?

would a 3/8 drive ratchet socket set up work to wind the back down or do u need a more bar

You change the rear ride height with the car jacked up and there is then no pressure on the bolt. As for lowering these the main limitation will be the length of the rear shock. I have a 4wd rear in an MY coupe so there are no bump stops. With the torsion bars wound right down the rear shocks bottom out. Would need to get shorter ones by trawling through shock catalogues to get the right lenght/rating. A tech at KYB was most helpful with this when I was looking for longer rears for a lifted MY. Was able to find ones with same end fitting, just a different length.

if the shocks are too long, get the rear shock brackets off a lift kit. problem solved

i lowered my brumby by trimming the bumpstops right down and worked fine.

afterwards i ended up actually modified them by cut and weld

Lift kit extensions will make the problem worse as they extend the shock, either a longer travel stnadard length shock or one slightly shorter would be better.
