I've had a quick schmooze on mytyres.co.uk and there are a few available in that size which I'd consider:

Vredestein Sportrac 5s

- I've had them on the Celica in 205/50/16 and they're very nice tyres, the side wall is a little on the soft side though

Uniroyal Rainexpert 3s

- Again had them on the Celica and liked them.

Toyo CF-2s

- My friend had CF1s on his Mk1, standard wheels and rated them for daily driving.

Falken ZEIX 914s

- generally well regarded tyres

Yoko AE01

- Not tried them but have had other Yoko tyres and they are good.
