I thought the EDC actually stiffened the outside dampers depending on the road condition...regardless of the current firmness selection. If one doesn't have this option, the dampers will not stiffen when you go around a bend and will probably roll more.

I found that Eibach springs made a big difference to body roll even with EDC.

BTW I have driven with leo and he pushes the car around. If anyone is going to find a problem with body roll, it is probably going to be leo!

"Electronic Damping Control

Electronic Damping Control (EDC) automatically adjusts the shock absorber settings to meet changes in vehicle speed, load, or road and driving conditions. The driver selects either "Sport" or "Comfort" from the iDrive "Settings" menu. EDC then modifies the shock absorbers to any degree, from the softest to the firmest setting. The result is exceptional riding comfort and fluid, responsive handling at all times. For example, the "Sport" setting increases firmness under all conditions for a sportier driving feel. With the "Comfort" setting, when sensors detect smooth roads, the shock absorbers are kept "soft" for optimum riding comfort. When the vehicle is rounding a sharp corner or curve, the shock absorbers are automatically and instantly adjusted to a firmer level. And when the vehicle encounters irregular road surfaces, such as bumps or a "washboard" surface, the shocks are instantly adjusted to the optimum level of firmness. This controls ride motions, helping to keep ride comfort at an acceptable level while maintaining road contact."
The bottom line is with EDC at the track it automatically firms up for corners, the EDC just alters the comfort in between them!
