You should definitely only use a race pad that can sustain performance in the 1000-1300F heat range. - I haven't used ENDLESS, but I run carbotech brake pads XP10 front / XP8 Rear
F.I. uses -8AN lines and fittings. -10AN might show slight improvement, but running those temps is common even with a 34 row. - Might want to look into a braking cooling kit

Which track did you have your first track day at?
