Hey there,
I can report a 1.07.864 (done during qualifying, measured from data) / 1.08.655 (done during a race, official timing). Both have been performed in a Griiip G1 during the G1series race weekend by Yarin Stern in Magione (19./20.05.18). Prove for both (for the Qualifying also the official timing) can be provided, if needed (mail me at toms@griiip.com).
Cheers!
