Still not cracked into the 13s yet but it's 100% there with a perfect drive, this wasn't the cleanest lap to be honest and was surprised it turned out to be my personal best around here!

New front rotors now needed as heat cracks are present all the way to the disc edge, running on 265/295 18" pirell trofeo r tyres.

Will be going back to 275/315 Ar1s and then come back to see if that will make the difference.
