i have done some weight reduction to my car. when everything is added together you will def notice it.
here are some of the things i did and the weight loss. some parts are replaced so you have to take into consideration the weight of the part going back in.
hood stock/ 33lbs - 22 lbs steed hood = 10lbs weight drop
wing/ -8
rear seat delete stock leather 50lbs - 10 lbs for seat delete = 40lbs drop
aluminum ds stock 22lbs - 12lbs = 10lbs drop
gutted trunk no spare or jack - 30
dogbone delete - 5
a/c and heat delete -35
that is my total so far -138lbs
im going to get racing seats also in the future. if you have a power drivers seat that is a -35 passseat is a - 17 depending on the aftermarket seat you go with. the ones i was looking at were about 23 lbs.
