Had my first crack with the car on sat.
apart from being an awesome time the tyres were excellent. only took a lap maybe a lap and a half and the grip was excellent.
the value for money is huge. the only thing, and im sure its like it with any tire, the tyre pressure really ballons after every session.
i started with 33 in all 4, after the first session i was loosing grip. came in and it had 55 in all 4!
So let them down and yer was excellent again.
i now have to upgrade my brakes as they boiled and lost nearly all brakes by the end of the day
