in the diff available in the e39 in any form?
or only as asc variants?
: Pardon my possible lack of technical knowledge, but what you are describing doesn't any make sense. I don't see how ASC can act as an LSD, distributing a specified percentage of torque to the opposing wheel when the opposite wheel is losing traction. Applying the brakes cannot possibly distribute torque across the wheels like an LSD can. Case in point, my friends 540 Sport with DSC activated was completely immobile when the right side of his car was stuck in ice while the left side (including the rear drive wheel) was sitting on clean dry pavement. An LSD would have applied a percentage of torque to the left drive wheel and the car would have moved......
: : From what I remember, they described the differential braking function of ASC as also effectively acting as a limited-slip differential. (The "+T" option, added to ASC as an extra cost option, adds the ability to reduce engine torque. AFAIK, in the US, only the complete ASC+T was available, so it was simply called AST for the US market.)
