Ginette G20 Race Car

[GinettaG20S2000]

I have recently bought a Ginette G20 with a Honda S2000 Engine. Looking to do trackways and some racing next season. Did first track day at Oulton last week.
I am looking for some advice on tyres - currently have Yokohama AD08R tyres (205/50/15) all round. Car has wheel arch extensions. I am looking to buy another set of wheels and slicks. What wheel type/size/tyre should I be going for?
