Weight obsession - part weights on S13

[Def]

I don't think there are diminishing returns at all, in fact, the returns INCREASE as you keep shedding weight. 30 lbs off a 3500 lb car? Not a big change, only 0.85% less weight. You would probably be hard pressed to really feel that. Now 30 lbs off a 2500 lb car, that's 1.2% less weight. 2000 lb car? 1.5% less weight. So it starts to become more and more apparent for each pound you lose as your car gets lighter.


I'd rather spend money on track time and tires at this point than buy other stuff, so I'm going to see how far I can really go with the stock panels while not making the car significantly less safe in any one type of impact.


Looks like lexan rear hatch window, remove as much weight as possible to the doors while keeping some crash protection, and then attack the rear bumper support.
