no weight at all, would not be worth the hassle and problems it can cause
yeah the back seat is only like 20 lbs, the only way your gonna lose alot of weight is stripping the car (passenger seat, back seat with back rest, spare and jack and all the panels) and that still wont be that much of a weight difference. Like IAmTheSTIG said go with unsprung weight a bigger difference.it's not worth it. your talking maybe 20lbs. The passenger seat alone will take care of that. It appears that there isn't to much weight that can be taken out so if i were you i would look into unsprung weight. That's the weight of items not being supported by suspension, such as wheels, tires, calipers, rotors etc... It's said that for every 1lb unsprung weight it equals about 5 or 8 (can't quite remember which one) sprung lbs.
So let's look into wheels, oz makes a wheel called the ultraleggera which comes in at 17lbs for a 18" wheel, i know that my factory 03 GT wheel came in at 23lbs, that's a saving of 6lbs each for a total of 24lbs unsprung which is 120lbs sprung weight, plus they look awesome (i might buy a set). Then there are 2 piece rotors which have an aluminum "hat" which greatly lowers weight of the rotor and helps prevent warping if your into track days or autox-ing or anything like that, you could pull and extra 5-15lbs unsprung with this. Then there are coilovers which also weigh alittle less and let you really dial in all the other mods you've made to that point and help the vehicle out tremendously.

after all that I removed, when I installed the roll bar and such I added more wieght. try using lighter wheels, sparco seats like I have a cf hood/trunk, lexan glass all around.More like 3 lbs. if you added the back's that fold down as well you might be at 20 lbs.
I took out all of my sound deadening, rear seat belts, back seats, a lighter drivers seat and CF hood I think added up to about ~100 lbs. If this is daily driven dont even consider it. My car is loud as hell whenever I drive it anywhere. The road noise is the only reason I still have a stereo in the car.
Just save your time and money if your going for performance in a 3g eclipse....or would it not be worth it to take them out? Casue i know the seat is just a foam piece, but i dont know how heavy the back part of them are, or the pannels. So if any one has taken them out or knows anything let me know.
Best answer yet.after all that I removed, when I installed the roll bar and such I added more wieght. try using lighter wheels, sparco seats like I have a cf hood/trunk, lexan glass all around.
Keep in mind a Spyder's upper rear seat should be much lighter (I would think). Feels to me like it is under 5lb. Definately not worth removing from a daily driver as it does a good job at reducing the road and exhaust noise. I'd have to imagine the rear interior panels are a mere 10lbs total, if that.Ok, thats enough guess work!
Rear seats & hardware weigh, 22lbs.
I agree completely - ESPECIALLY on a daily driver and an Eclipse at that.Or just go jogging a few times a week and shave off some lbs. Basically, it comes down to ripping your car apart isn't worth the .01/.05 sec you may lose on your quartermile. Hell, driver error can probably help out your car becmoe quicker better than stripping shit out of your car.
and im guessing if you can mount it at any angle it has to be a dry cell battery. also alot lighter then a optima. i work at advance auto and the lightist battery we have is a yellow top. and i think its running around the mid to upper 30'sWhat's the point? Even if you drop 20lbs off the car, its still slower than piss.
Best answer yet.
Also, consider dropping off unneeded equipment, A/C system, etc. Your battery alone weighs approx. 42 lbs. I'm soon going to start offering a lightweight daily use Carbon Fiber battery that weighs HALF that at 21lbs and can be mounted in any angle.
