For the first time this year, a group test day was topped by a manufacturer other than Honda, as Sena Sakaguchi set the pace aboard the Yokohama-shod #19 Toyota GR Supra with a best time of 1m43.206s in the two-hour morning session.
That was almost three tenths faster than Sakaguchi had managed on Thursday, but still six tenths away from the blistering new unofficial lap record of 1m42.630s set by ARTA Honda man Toshiki Oyu.
