I can tell you from expereince that cutting you reo is a BAD BAD idea, even if it's only shaving say 2-3cm off it. If/when you hit someone you'll totaly FCK your cooler, radiator fan, fan shroud, head light mounts, bonnet latch etc etc. That reo does a LOT of work holding everything in place, when it bends it tears shit apart.
Trust me, I know. Go and buy yourself an ARC cooler
