interesting, wheel set at 600 in the windows controller advanced thing, don't change it for GTR2 / GTL or any rFactor Mod, i just adjust the in car steering lock until the muscles in my arm relax and i'm working the wheel without thinking about it, if i run too high a steering lock my arm start freezing and sort of lock up, normally start at 10 then work my way up, yes and sometime you come to the first corner and just sail off the track for a burger, once it's close-ish, ie: feeling right, then the rally driving starts and if i can catch most of the slides that will normally do it for me, but i might re-adjust again once my lap times come down a bit and my driving style smoothes out.
but as with most things in GTL/GTR & rFactor everyone does there own thing and most of everyone gets round the track at a fare rate of knots, think this also effects how one persons setup might not work for you or me, but works for them.
