I cant help with the specifics on your Camaro, but I have been reducing weight in my truck and myself. The truck (1946 Ford) is down to 2740 lbs now (rear fenders and hood not mounted though). Replaced everything possible in motor with aluminum, aluminum hubs and calipers, lightened bumpers, aluminum fuel cell, aluminum steering wheel, lighter seat configuration, alum bell housing, etc. Someday will put in an aluminum flywheel. Aluminum replacements are expensive. Something like $40 per pound saving and above.
