Ricardo,

No, the "snow chain" switch simply allows a little more speed differential between the front & rear wheels, thereby allowing a little more "slip" than in standard configuration.

Senior Hendy,

All good points you've made, but you are a highly trained Pilota (or in Italian is it "Pilote"?). Somebody like me in the rain, with ASR defeat, would likely loop the vehicle and kill both the vehicle & themselves.

If you aren't used to high-power vehicles, don't do the ASR defeat switch unless you know EXACTLY what you're getting into. David can absolutely deal with it, and I'm sure Alain, Dean, Tackman and a few others would be fine, but I know ASR has saved my hiney a few times...
