Ibiza Gtb2566vk new setup testing, Knockhill track day 7/6/26. Bad tyre choice for the day

Testing out the new setup. Since the last track day; Bigger turbo, injectors, ARP stud and nut kit, oil cooler, bigger alloy radiator and few other bits. Slippy track and I only brought road tyres with me as I wasn’t booked onto track and didn’t expect to get out
