Not a Toyota but you guys are quite knowledgable so here goes.

Who I can talk to, to get some roll centre adjusters made? or is there a kit for early EVO's available? Also bump steer correction as well?
For stock EVO 3 arms. I know there a kits available for EVO 4 onwards but the arms and hubs are different so the ball joints are different.

I know kiwi race cars can but not sure whats going on with them atm

Hey Cam, do you know Jarred Bird? He did this to his Evo race car, might be worth speaking to him.

Have spoken to Jarred. He upgraded to later model EVO hubs and arms, but then went to Racefab custom arms with rose joints etc. I just want roll center adjustors at the moment.

At the moment I have to raise my car up quite high to achieve the desired bottom arm angle, but then i'm also raising my centre of gravity which isnt ideal. With longer pins on the bottom balljoints I can set my suspension lower without hurting bottom arm angle, and lowering my centre of gravity.

Richard Grainger has an early evo in GT something, i think Dtech in tauranga did most of the work on it, they'd be worth a ring

fortyone do them, but they ain't cheap. I'm assuming this is what you're after?

Yeah those are what i'm after, unfortunately they are a different design and are for the EVO 4 onwards hubs.
Early EVO balljoints are tapered with a thread.

Jarred previously tried roll center adjustors you can buy off the shelf etc and they were shit. what he ended up with was nick from mag and turbo palmy setting up an adjustable height steering knuckle that accounted for the change in geometry. nick sorted out bump steer etc and it dropped 2sec off his time at manfield.

For what you spend of aftermarket parts a proper race car setup and small amount of modifications you'll prob notice more improvement in times.
