I typed out an (unusally for me) quite long reply but got some error when I went to post - but from the experiences of a GT3 driver at the ring having seen a few RSes out there last week then assuming you can extract the benefits from the tyres and aero then I don't think you'll be disappointed; it's damned fast in the right hands.
