| Not an SS, but a 2-Valver nonetheless. One word.... Diablos !
I had some on my ST2 all last summer, did Cadwell and Rockingham on them. At Cadwell, they gripped like a leech and simply wouldn't budge. At Rockingham, well, nobodies tyres gripped at Rockingham once it rained but in the dry sessions I was circulating in the fast group without too many people coming past me and it was the same story....they just grip and when they do start to move they do it very predictably. They moved a bit more at Rocky, but they were already 4000 miles old by then.
Anybody who needs the extra grip of corses on a two valver must be very brave indeed |
