Hey there,
Can suggest 2 summer tyres as very good, both yokohama and toyo, although toyo provide even more grip, they are quite soft (hence the good grip), but wear quite fast, (front tyres within 12500 miles).Yokohama little les grip, but only worn at over 20000 miles, so just what you want more grip or more durability. (for reasonably priced tyres).
Michelin pilot sport is the absolute best, but at prices close to 160 Euro per tyre :-(
Hope its some help to ya,
