A brief update...
The NS2R's were removed as two were faulty (had been sitting and had developed a problem it seems), so I've replaced them with a new set of Avon ZV7 tyres. Although reviews on these are mixed, the car is unlikely to get much track action so a decent set of road tyres are probably a more sensible option anyway. They are rated as A in the wet, and 69db noise levels so a lot quieter than the NS2R's were. So far, I'm impressed! As I said, reviews online range from brilliant to terrible, depending on what link you click and what car they're fitted to.
For me, they drive very similar to the Pilot Sport's I had fitted on my last Clio, very good in the wet, no aquaplaning or weird characteristics in heavy rain and standing water and even if pushed hard in the wet they grip really well - and they're not even scrubbed in great yet, so hopefully they'll get even better. Same profile as before 195/50/15 so no visual changes really to report but thought I'd add the info in for anyone interested.
