2.44.xxx during practice session on R5 tires front and rear. I can still get faster if I spent more run.
Brakes, LSD, and DOWNFORCE kept stock. I used tranny trick.
For 24 hr endurance I used R3 rear and R5 front but only during the first 4 hour, then I passed the rest to B-SPEC on R1 R2 tire combination pit every 7 lap
