I need to replace the budget tyres on my Roadster with something with a bit more grip, both in the wet and dry the grip they give is not good to say the least. The problem is finding good tyres in the 185/70R13 size, it looks like Uniroyal Rain Expert 3 is the best at the moment.
You don't have a lot of choice in that size, do you? If I were in your shoes, I'd probably go for the Uniroyals too, although Kumho V70A trackday tyres are available (Demon Tweeks seem to have some) in your size.
