Perhaps a little Jim, although the Glen's track surface has a lot more detail/bumps than most of the other circuits. A few of the waveforms are squaring off but a little clipping is nothing to worry about especially if you like the feel of your wheel.
P Cars is frustrating because there is not one setting to fit them all, then you can just work on car setup. You have wheel profiler settings, wheel ffb calibration, car ffb settings, then car setup and also track mesh construction to consider, quite frustrating really.
