Default rear torsion bar indexing question.

Ok, so if I jack up the car, undo the four bolts around the torsion bar plate thing, pull the bar out and rotate it one or 2 splines or so and put it all back together the rear will be lower right? If I make sure I take note of the positions I shouldn't need an angle finding tool??

The car is getting corner balanced aligned etc later on, I just want to have a play around with heights before I get it fine tuned.

Thanks!!

Yes, as long as you rotate in the right direction.

Mark the position of the springplate with no load - the bottom bolt removed (the lower one - tire side). Then you play. Each notch is a fairly large amount. For a subtler drop, rotate inside one notch & outside the opposite direction one notch.

Thanks a lot Ian.

I just have 2 quick questions!

a. can I do this with just one side of the car jacked up at a time?
b. do I need to split the spring plate, or detach it from the trailing arm, I image it wont be easy moving the whole lot together.

Yes. Carefully.

No & Yes. No, you don't have to split it, but you might want to, to centre it if nothing else.

And yes, you have to detach from the trailing arm. You have to remove the toe & camber bolts. Mark them first for position. Then the trailing arm bolts. Be cautious here because the springplate is under significant tension. You have to support it with a jack to get the bolts out anyway. While it's still jacked, remove the one bolt on the springplate cap. Then lower it to rest & mark.

Reverse the procedure to assemble.
