How much you think you could save in weight ? as i was thinking one day to do this myself..... 1 peace fiberglass ( tilt ) front end... Wack the firewall and everything fwd off and tube frame with light weight suspension and manual stearing....
Its been done thousands of times to hundreds of diferant cars.. ( pro street )
You could save a lot of weight doing something like that. But if you don't do it right and/or it's not designed well, it will end up just being a heavy paperweight or worse falling apart while you are driving. You would also need a pretty solid cage/rear half to build off of. But that's way past the car being a supra besides in appearance.

all those weights up there are great info, might be a good idea to compile that with the other weights list before this thread gets lost in time.
As I suspected the hood is far lighter than most people realize, even if you did take some bracing off. The doors were the thing I thought were going to be the worst and looks like thats the case. Too bad you cant just skin your cage and use window nets or lexan
The subframes are heavier than I thought they would be. Customizing your own with tube would be cool and I would love to see what you come up with.
I seem to remember a member here has their weight as part of their sig and its in the 2900lb range on a street car. I forget who that was/is but it certainly seems possible.
I will be compiling the weights and many more. I have another Supra coming sometime this week which is the one we will be building. So there's a lot of stock parts on there that will get weighed. So I can add them to the list.
The hood really isn't that heavy for it's size. It seems like most of the aftermarket hoods are the same weight or similar. So it's more of a looks upgrade than a weight one. I would love to see a proper CF hood. Like one or two layers of CF, aluminum or nomex honeycomb and then another layer on the bottom. Under 10lbs, stiffer than stock and would probably cost more than I have paid for any of the supras. But it would be sweet.
As for the doors being the heaviest, they are, but they aren't that bad. And most of the weight is because I want to keep it there. I could get rid of the windows and run nets if I had to and get rid of the speakers and then cut the door frame. That would save some weight. And I'm going to look into gutting the door a little, but I would still like the window to work, so we'll see what happens. I mean when the other supra gets here I will have 6 doors. So I could spare one of the banged up ones for some R&D.
The subframes were pretty heavy, I didn't think they would be that bad, but they were complete. I mean if you drop wheels from that, it would be 100lbs less. And then brakes weigh a decent amount. The diff is there in the rear and the steering rack in the front. And then the hubs and spindles. And then you're left with arms and the actual subframes and it's not nearly as bad. They'll be getting totally torn down and reinforced/modified/etc so I will take the chance to weigh them bare when that happens.
I would love to remake them, but it would be a ton of work. And being the suspension engineer nerd that I am, I would want to redesign the suspension points to make it perfect and it would just take too much time and it would be time that I wouldn't be able to make back. I don't think there are many people in the MK3 community that would pay good money for custom subframes, but if I'm wrong, maybe I'll push it up on the list.
2900 is possible for a street car. It's pretty bare, but it's possible. I'm pretty sure we were under 3k with the car setup the way it was before. And that was pretty much just from removing all the stuff we didn't need. And for this build, it's going to be a car that can be driven on the street, but it's really just going to be a race car that is registered and insured. So definitely not for everyone.
