Springs and bump stops

MCA can make shocks to fit torana’s. They make really nice stuff.
Spax do a shock to suit
A mono tube style shock reacts much faster and can control bumps better(bilsteins are this)

If your planning on using the car on the track you may open a can of worms. Power steering is advisable and changes to wheel align more positive caster. The rear ends generally need work too, need to get the articulating as freely as possible, will help them hook up better out of turns.

Thanks for more info, I’ve been researching and investigating. COVID isn’t helping bilstien and Lovell both have issues with supplies and don’t have any real clear eta’s so it’s a bit of a bummer but we’ll move along. Cheers.
