Well i just weighed my car last night, i removed the carpet, sound deadning material, and firewall mat, well about 90 percent of it, there are some spots where you would have to take basicly everything out to get it off. Neway I also had the back seat cusions out and the passenger seat out.
The rest of my weight reduction consits of no a/c inside the bay at all, none behind the dash at all, no front or rear bumper supports, no power steering, no abs or sunroof (base model se-r) No exhaust on the car other than the header at the end of the 2.5" secondary, no heat shields under the car. Anything in the bay that didnt need to be there was removed. No unnecessary brackets on the motor.
My weight without me in the car with the needle almost on the E line. so about 1.5 gallons left in the tank i came out at 2080 lbs.
I still want to get the carbon fiber hood good for about 32 lbs, a 9lb battery to replace my monstrous duralast gold, good for another 33 lbs, once i get a daily driver i will remove the back seatbelts and all the back panels. Im gonna leave the door panels though. Should be good for around 20lbs maybe more. Then lastly i eventually want to do the quarter windows and rear window in lexan, good for probably around 40 lbs. So all in all i can easily be sub 2000 lbs without doing anything crazy like door cutting or no dash, door panels, just basic removals that if ever needed i can put right back on.
But then once i turbo the ve motor the weights gonna go back up a bit being the turbo kit and intercooler are quite heavy compared to an 18lb header.
