Can anyone tell me how to adjust the toe in on the rear? My sons baja has been converted to irs and at the moment it's going through a facelift and I noticed his rear tyres are very worn on the inside. I've tried googling this but couldn't find anything anywhere. Cheers

The spring plates are slotted for just this reason, sliding the axle towards the torsion bar gives you toe-in and away from the torsion bar gives toe-out. Just off my head 0'50" toe-in on both wheels or 0'0" on both or 0'50" toe-out on both.

That's what I thought but I've tried them all the way forward and still get toe out! Methinks I'll have to persevere, thanks anyway.

Is it an original IRS chassis? If not then if the A arm bracket is not welded in at the correct angle you are unlikely to correct via the spring plate slots.

Also, if any lengthening of suspension parts has taken place for increased travel for a Baja then again this will cause issues if not done correctly.

Oh, and being as it's a Baja then maybe the A arm has gotten twisted from the off roading action.

One remedy to excessive toe out I have seen used is an eccentric inner trailing arm bushing.

Whats the camber look like? Being an offroader,has it had suspension jacked for clearance?

On the inside pivot point, make sure the big thick washers are both on the outside.
Despite what you think would be correct, the factory setup is NOT one on each side.

I thought about this and being irs the slotted holes really wouldn't make much difference as the axles aren't pivoting at the gearbox so would only move the wheel back and forwards in the same plane and now thinking back you ,Dave may have hit the nail on the head. I bet I put the washers on wrong. Cheers chaps!

The slotted holes can make serious changes to toe in or toe out.They can also make camber changes,but only very slight.
