Has anyone installed a single sway bar on their FWD Volvo? I have a base 850, which doesn't have factory bars, but have upgraded with Eibach progressive springs and Koni FSDs. Ride is good, handling good, but I would like to reduce the little bit of roll that I still get. There are some vintage Volvo owners that maintain that they have had the best results running a sway bar in the front but not rear. Seems that with a FWD car, installing a rear bar (but no front) would decrease roll and understeer and improve motive grip to the front (not to mention cutting costs by half). Has anybody tried (or researched) this?
