Thinking about going back to using track day tyres (R888, AO48s etc) on track days. Currently running AD08s which are good but just lack the outright grip that the dedicated track tyre like the R888s offer. I've used R888s in the past so know they are superb. However, I'd like to hear people's thoughts on the other ones out there. I know there's the Yoko AO48s and a Dunlop ones but that's where my knowledge runs out. So! Advice please.
