Weight reduction bro Options

[Wannabesupra]

I'm new to this forum so hopefully im posting this in the right place. I'm looking to shed a few pounds in my 3sgte swapped 94 Celica st and I'm kinda wondering where to start. I don't want to completely gut the interior since this is gonna be a summer daily.

I figure since the back seats are practically useless in these, taking them out would probably cut down on weight drastically (anyone know how much they weigh?). I've got a leaking gas tank too so ill probably switch to a fuel cell to cut down on weight as well. I may chuck the spare tire too but this is a daily so I'm kinda iffy on that. Anyone have some more suggestions? Thanks!

The rear seats really don't weight that much, they're just foam and cloth/leather and they insulate the back of the car from road noise significantly. Plus then you can't carry stuff in the cargo area safely since you won't have the rear seat to stop **** from flying forward and hitting you and a passenger in the event of an accident or hard stop. There's more weight in the rear seat belt assemblies anyway, so you could at least remove all of that I guess and if you don't care about road noise could remove the seat bottom for whatever minuscule weight is saved there. Maybe could replace the seat backs with particle board cut to shape if you still want to carry things, but that'd be a lot of work for little if any weight saved. Might as well chunk the doughnut spare since it's long dry rotted by now and replace it with a tire patching kit. Lithium battery as well as Carbon hood and lift gate would save weight without effecting the car negatively, but at a cost. Somewhere else to look into weight could be your rims, 14's are going to be lightest but won't clear some of the bigger brakes. I don't foresee a fuel cell really weighing much less than a fuel tank unless you go smaller, then you run into installation difficulties versus a stock replacement. Ehh, outside of that you're starting to make compromises to how comfortable and livable the car is. You could chunk the A/C(provided it has it), stereo and speakers, as well as the power steering system but now it's a miserable experience driving it unless you just don't care about those things for minimal weight savings. It's not like these cars weigh much to begin with, and any small losses will be barely noticeable in a stock ST much less one with 2-3 times the power in it now. You're better off putting any money that'd go into weight savings into good tires, suspension, and brakes to support the power it has now.
