You can take out the sound deadening if you don't mind the extra noise. With my back seats out plus the sound deadening i knocked out a hefty amount of weight.

Taking out interior weight can save 100lbs or so at most, if you take out EVERYTHING that isn't needed for the car to run. That includes the dash, seats, carpeting, etc.

Once you start messing with exterior panels and such, you are compromising the safety of your car.

Unless you are real serious about racing, keep the diet of the car limited to interior panels/parts... and, sorry to say, it won't be all that much.

My plan is to remove the back seats (which are totaly useless), and MAYBE replace them with a cheap sub. So that won't mess with the 53/47 weight distribution. Then, after I'm done with the most important handling/power mods, I could think of a f/g hood.

Will moving the battery to the trunk substantially affect the f/r wieght ratio? I'm thinking of taking out the backseats, but I don't want to disturb the near perfect 53/47 balance.

The back seat hardly weighs anything...I took mine out though. I just couldn't bear to take out my jack and spare tire, coolant, oil, brake fluid, and WD-40????
I know I could drop 50lbs w/ all the *essentials* (well that's what i call them), but in the long run it doesn't matter too much.
IMO the best way to weight reduce, would be to take out everything from the front seats back...and move your battery to the trunk. It would be lighter but the balance wouldn't be off too much.

Thanks for replying! I wanted to also know about the aluminum drive shaft. Better take off, less weight,etc,etc. Thanks! -240GT-R

the weight distrabution(SP?) probally varies between the coupe, and hatch. I would imagine the hatch to be a fair amount heavier in the back.

It is not that good at all. I remember talking to Don Nimi about corner weight balancing. He said something to the effect of "It is not possible to get a 50/50 balance without making the car look retarded or moving around a lot of weight."

I think he said on his car, the best they were able to do was 54/46. I think stock is even closer to 60/40, maybe something like 58/42?

Anyways, moving the battery to the trunk should help out. The car is heavier in the front stock.

What do you think the distribution of an SR20DET in a datsun 510 is? http://www.freshalloy.com/

You can make it 50/50 with some wider tires and rims in the back. This also provides more traction.

You can also install 4 subs and a box in the trunk. That might even push it to act like a mid-engine car. =p

you can do like me.. you can pour some slim-fast in the gas tank, lock up your engine, and take it out to replace it. that lost a lot of weight. LoL http://www.freshalloy.com/

hey i was wondering if you do weight reduction, can removing things like the back seats, etc. mess up the 50/50 (or as near as) weight distribution?

I've removed all of the seat belts(including front+rear reels and rails) and that netted 37 lbs. I'm using a single harness now that weighs maybe 3 lbs. Spare tire and jack are removed.. those were 29 lbs if I remember correctly. Cruise control is coming out today or tomorrow(i'll get the weight up when I finish). Power antenna is gone entirely, that was a few pounds. Stock amp, gone. That's about it for me. Hope that helps you out some. http://www.freshalloy.com/

Why do you want your car to lose weight? Are you drag racing? Like Alex said everything out of the interior you might save little more than a 100lbs.

If you ask me its not worth it, for every 100lbs you only take off a 10th of a second in a 1/4 mile. Your interior will look bad, it will be noisy and your really not gonna be any quicker. I would just stick with taking out the jack and spare.

lightening any of the rotating mass will make a bigger difference than removing dead weight. so light wheels and a c/f driveshaft and light flywheel will make a bigger difference than removing interior. plus im not all big on removing weight in the back just b/c i want more there. replace that heavy battery and front hood too.

heavy wheels or large wheels will kill your acceleration
