I've not bothered to look at all the links but I've heard that the Avon's are good tyres but not very well structured. A friend had them on his 150bhp Primera GT and had2 or 3 issues with the sidewalls of the tyres
Personally I'd go Falken ZIEX ZE-912's if you can find them as they're grippy in the dry, not awesome in the rain but you dodn't need to drive as hard in wet conditions and last forever
If not then again try and source some T1-R's if you want grip but be warned they wear quickly
Kumho KU31's I had on my car before and never had any issues with wear etc but I can honestly say that of all the tyres I've had onl;y the T1-R's can compete with the Falkens I've had for grip although there are many better tyres out there I'm sure but they'll be more expensive
