So ... as Curt would say ... this is definitely a slippery slope ...
So I learned that a set of Weltmeister bars both set to a mid bar setting definitely makes the S2 a lot looser in the rear than the stock bars (so I yesterday softened the rear by moving from 15mm to 7mm from the bar end)
But I am still a bit confused by differing opinions on tire psi (let's just talk in COLD psi for purposes of this discussion) ...
I ran the RAs at 31 front and rear (both 225/50 x 16) and never fiddled with it on Saturday ... and I got heard from a couple of people that I should drop the pressure in the rear a few lbs to increase grip ... BUT I heard from another person (who should know) to increase the psi in the rear by a few lbs to stiffent the side walls and increase grip.
Now I know that there is a continum where a psi of 0 lbs or a psi of 1000 lbs will be no grip extremes but where/how does psi affect grip in the middle 20 lbs to 40 lbs range??
