I see there is a S-H label above the stick. Maybe a Softer/Harder sequential selection for the Front ARB?
OK I have the answer. PB is correct: it's the front anti-roll bar adjustment. https://twitter.com/LucianoBacheta/status/247816511249588224
Impressive how today one can communicate with those at such high level sports that commonly used to be something we could only read from magazines or saw at tv, may the common man have wisdom not to overload such communication channels and we all will be rich, or something like that.
Post from WMD forums: This is what Luciano Bacheta told me on twitter just now about the F2 handling in rF2: "i think it's as close to the real thing as you can get without spending huge $$$. I drive both f2 and rf2 the same way." Seems a pretty good endorsement!
Actually it was easier not a long time ago. Dont know about GPs as they are far away from me but it was really easy to come close to rally superstars at Acropolis Rally. I particularly remember Didier Auriol with his funny sunglasses, having stopped with his Lancia at a turn, in his way back after Super Stage, and enjoying a relaxed talk, out in the sun, with his coodriver and a couple of mechanics. We could go near them, ask for autographs, some people even joined the conversation. I didnt, didnt want to bother them, but they didnt mind at all having us close by, overhearing their sayings. (I even remember Auriol taking full notice of my wife's miniskirt lol). The year was...1989? Try do the same now. Yes Another campfire talk lol.
I think that at least some of relaxed way of rallying still exists, but of course less today than before, with formulas it is just business with walls usually.
