Torsion bar/shock options

Yes mate, by track work I mean circuit/saloon racing. I'm looking at the sticky rubber too, and thanks for the heads up on Spax shocks, I'll Check them out.

As for compatibility, for all intents and purposes an Aussie Val is an early A body car underneath. We got. 890 or. 870 torsion bars in the earliest cars, and they softened them up a bit as the years went on. Other than that we obviously have right hand drive architecture, and I think different knuckles or at least disc brakes and calipers to the USA cars. My car already had rack and pinion conversion, so steering box woes aren't a concern to me.

Great!
SPAX was running out of the bushings for those shocks. I think the second set I bought may have come without the bushings for the rear shocks. But I'm sure you can buy aftermarket in polyurathane, nylon, or maybe even rubber. The Aussie shock mounting studs are a slightly different diameter than the North American made A-bodies.

Yes. Australian Valiants have a different disk brake caliper and hub. We should compare.
The earliest disk and calipers were Girlings. As far as I know, never production, but prototype done for rally in UK/Europe.
Production was a Kelsey-Hayes 4 piston fixed caliper.
A fellow here used longer Aussie disk brake wheel studs on the Kelsey-hays hub rotor. The shoulder is a little shorter, otherwise they fit.

Maybe you can find some larger torsion bars locally from those who used to run circuit. If not, Firmfeel is on the US west coast. They make bars in-house. In my experience, bars up to and including 1.03 should have the hexes clocked.

You really don't need much to get on track just for fun with these cars. Wheel to wheel racing of course is more involved.
