Have run Ad08R and RS on my elises for a number of yars now - first Elise SC and now on the Cup, always been great, plenty of grip and still reasonably good in the wet. BTW I went 205 / 45 /16 fronts without problem. Many other folks did too
Unfortunately Yokohama have discontinued them for the UK market, I beleive they are being replaced with Ad09RS - the bad news is not in Elise tyre sizes
So enjoy them while you can 😎
