i think that is 2 secs at Anglesey Costal circuit which would be probabaly 4 secs at donny and 5 secs at Silverstone - probabaly half of that down to Cups:thumbs:

2 seconds per lap on a very short Anglesey 1 mile Circuit is a big difference :beer:

Maybe a bit more than that Andrew? Apparently, 70% of the 32 second difference in the Ring time, between the standard M3 and the CSL is due to tyres.... M3 was tested with Sport contact 1 tyres.
