GT ONE Spa 8 hr Race

can anyone give some context for this race?

apparently it was broken in an update. in what way? what was different before?

i tried some attempts but the difficulty is all over the place. the two McLaren Longtails run 2:10 in quali on softs. i run 2:08 in the CLK, 2:12 in the longtail and 2:14 in the GTR.

doing the race in the CLK is too easy, it sips fuel and is easy on the tires. the longtail seems to be balanced the best for it's chili rating and the two chili GTR seems impossible. it chugs fuel and eats it's front tires. i don't see me winning in that car unless there's a lot of rain.

has anyone experienced the same? would you agree that this is the hardest Power Pack two chili race?
