The PSSes (stock size on stock rims) went on this morning. The guy forgot to check the rear tyre pressure(?) and I didn't have time to do so, and I didn't really have a chance to drive it in anger. That aside, I immediately noticed sharper-feeling turn-in, much less chance of chirping the tyres, and generally better steering feedback (the trade-off being an extremely slightly harsher ride at low speeds). At the same time, for some reason it feels slightly vaguer around the centre, but only insofar as it is much more confident at more extreme angles. Greg, I see what you mean about improving steering feel. I think that if I did those mods, the car would get EVEN MORE H4RDC0R3!1111!!11!1!1!1!! Would camber bush on its own (without your specialist springs) be sufficient?
