I would like to know the effect on ride quality. You realize, of course, that a fully independent suspension becomes a little less so when an anti-roll bar is installed. Added to the twist beam rear suspension- which renders the setup as "semi-independent" there is a lot of cross-linking going on there. Though I was disappointed years ago when Volt appeared with the current rear setup, it has worked well, especially in Gen 2 and neither I nor anyone else seems to find fault with it. The question is: did Chevy leave off your new bar because it is not beneficial or only because it is an extra expense and weight? I would like to see Motor Trend test your car against stock to get all the answers from neutral parties. In the meantime, how's the ride quality?
