Thanks.
Was a little slippy out there
Running on R888 all day. 205/45/15 225/50/15
Had a major problem with Aquaplaning in the morning and the car would spin up it's wheels after 80mph down the normal start/finish straight.
It was probably 50/50 on weather a road tyre would be better by the final run but I think the R888's had the edge.
