The best bit for me was when they fire in the pits, your ears are bleeding, the nitro is burning your entire intake tract, your eyes are flooding with water, your dry heaving.....
Then they rap the throttle once and your heart stops!!!!
I almost collapsed
ABSOLUTLY FUKIN AWSOME!!!!!!!!!!!!!!!!!
Down the end of the track when they go by was a close second, even from 40ft away 310mph is terrifying!!!!
