G'day, We use the R888 on our track day car (Turbo Nissan Gazelle) in 16", and although noisy when pushed, compared to Bridgestone Semi slicks we had before, and maybe not quite as grippy, they are certainly very good value for $$. I read a tyre comparison report in December Motor Magazine, and they were not rated as good in the wet,( I have not used them in the wet as we put road tyres on for wet days.) They will certainly be on top of my shopping list when the time comes, as I hope never to test out the wipers on the Cobra, (But I do live in Melbourne)
Peter.
