If you think about what happens when you lower the mount for the top arms or lower the whole rear suspension you should see how it forces the roll centre higher.

That's you is'nt it Darren.......wondered how long it would take you to get on here, hahagday guys, may have missed some of your points. jst letting you know. i use an adjustable watts linkage setup in my lx 4dr, and i highly recomend fitting some form of panhard or preferble watts linkage if your seeing track work. one problem with running either setup is. as was mentioned it lowers or tricks the car into having a lower rear roll centre. this will cause the front end of the car to sometimes react not in a psitive nature coz the roll centre is still wrong at the front. im working on correcting this in my own car.

It still makes sense Greg. Just trying to work out what can and can't be done.Chopper,
Yes the parallel with Watts is ideal.
I wouldn't make a roll centre change to dial out understeer/oversteer unless it was a BIG push.The problem with using roll centres to adjust car balance is that a small change in height can yield a large change in handling characteristics. The other reason you should use bars and springs to tune your under/over steer is that you are only changing one thing at a time when you make a bar change. When you make a roll centre height adjustment it changes the roll couple angle so the jacking effects are altered at BOTH ENDS of the car.
Is it getting complicated again?

Hard to say, at Phillip Island it understeers at Southern Loop and Siberia, both left handers, but there aren't really any comparable right handers,Hey Mick..... is the Commo consistent on both lefts and rights? Or does it understeer on one and oversteer on the other?
