No I just hate to see a nice supra interior destroyed just so the weight can be dropped by a 100 lbs. And with the rotation mass I have seen as people write as high as 1lbs Rotational = 20lbs Stationary or a low as 1lbs Rotational =1.4lbs Stationary

100lbs is not anywhere near equal to 1 second in a quarter mile... I've seen people gut the holy hell out of these beasts, swap out as much as possible with carbon fiber and aluminum and still only end up with a 3200lb sloth (but hey, it used to be 3500)..... they still sucked in the quarter mile and was now louder and more uncomfortable to drive than the lack of gains made it worth. If you want better mileage... try to lighten it... if you want more speed get a bigger turbo and throw more power at it.

The stock seats are HEAVY.... either get aftermarkets or seats from another car and build your own brackets, track down a JDM Recaro set, or just swap out the electric LH seat with a LH seat from a JDM MKIII (so you'll have a matching non-power set).

A lighter one-piece drive shaft will help, but not just due to the lowered rotating mass but because of the reduced frictional loss in the center carrier bearing and U joint. Get steel if you go this route it handles the stresses much better than aluminum and won't grenade nearly as soon. Any one-piece drive shafts should be checked every few thousand miles for cracks or swelling near the center.

LOL

From what i've heard 100lbs is equal .1 second in the 1/4 mile, sorry green I didn't pick up what you said before. And for mike91, let me get this right this right. You want to gut the interior and maybe shed a few tenths off the 1/4 mile, ok great destroy a nice supra. But then you talk of installing rubber coating and carpet which have weight to make it quite again. So in the end how much weight will you really save? Maybe you should just buy a honda or hell buy a miata and put in a v8.

the rubber coating im more than sure isnt that thick at all. they sell the stuff at auto stores for noise insulation and to help absorb vibration. i really doubt its heavy. prob if i sprayed the whole inteirior it would prob weigh 3-5pounds? besides that the a/c system does it need to be drained if disconnected?

Well if you are taking out the a/c and with it probably having r12 in it which sucks for the enviroment then you should have it vaccuumed out first. And a little bit of rubber coating won't do anything to stop the sound. What do you think the panels are made of ? Steel. They are all mainly plastic. What color is the interior?
