cheers for all the comments guys.
was just a bit of fun out there, giving her a thrash.
a LSD woulndt go a miss, just not in my budget at the mo.
Car had small issue towards end of first session, we got pulled back into pits and i decided to cut the engine, but it wouldnt re-start. Down to the crank sensor. They over heat and stop working, but its being replaced by a more reliable one as we type, so shouldnt be a problem for future.
Car has got 4 pots on, which was helping me come down from 120mph to the tight left after the main straight. Car was a little bit slidey at times, partly do to massivly heavy braking, and part due to me pissing about a bit.
