Lighten up my race car

Looking for advice on best way to lighten up the dart. Motor is a fresh 340 with eddy heads electric water pump ,altercation front k, glass hood,bumpers and aluminum bumper brackets. At minimum will get glass deck lid. Thinking of fenders and doors, never had glass doors before do they have any way to let air in on drivers side while staging . Roll up or sliding lexan? Motor is freshly dyno tuned 460 hp at 7 k so not willing at this point to touch it. So have to get lighter to go quicker. Still has full glass in rear quarter windows and doors. Advice,opinions,who to buy from is wanted.....GO!
