Pete, for people that havent ran at Seaham, do you mean that yellows arent lasting long enough but you get lots of grip or are you thinking blues just because they last longer due to them being harder.
For me, ive got loads of tyres from other events that will be ace for Seaham(apparently!) so buying Blues is a bit crap. Most people set their cars up using yellows so going to Blue would make setups change aswell.
Not a dig but just want some clarification?
