Carlos from Spain:
Having driven 911 with ABD only and 911 with LSD, I can honestly say that ABD is not substitute for a LSD in a sportcar.
Carlos,
Wouldn't you have to say that your statement might depend of the development of ABD in previous Porsche models vs. what might be achieved now by McLaren?
