I agree, car setup seems to be a factor influencing a lot of this discussion.
I also agree with the point that a fast spinning wheel doesn't lose traction enough. Sort of like the slip / traction curve levels out at some early point, when it should still be going sharply down.
The rwds exhibit far more normal cornering behaviour when set with a fairly neutral setup to me now - throttle on understeer, have to get a bit vigorous to shake the rear end loose. Previously I was unable to make the xrt drive at all like my rx7, my sets now feel pretty close. Tyres search for traction when slipping, rather than just floating around. All very good. Still doesn't feel like enough of a bite when correcting a slide, but part of this 'may' be to do with the lack of real forces being applied to my body
