Wow, strip it....haha no way was i going to loose the cush and power push of the stock seats, but those you're getting do look very attractive if you're going to go the seat delete way. Yes they really are that heavy once out of the car.
glad to hear youre hub swapping, i have a set of twice used adapter billet aluminum ones, but I don't like them for some reason. But they do work. I still haven't hub swapped yet, but looking for the stuff. I like the look of truck bed line X, for floor covering on the 4x4's, but that would defeat your weight shaving goals. I'd use flat black spray paint instead one you wire loom everything out.
replacing the doors with fiberglass would actually add weight once you brace them and add gussets, resin and braces everywhere. (Carbon fiber on the other hand......)
. The Mark 8 doors are actually lightweight for what is there. Just thin sheet metal and a thin cross brace for T bone protection. The biggest weight of the doors is the glass and regulators/motors. Take all that out and get some lexan windows cut, (held in with some nice aluminum channel trim and setscrews) and you could save weight there. Front and rear bumpers can be trimmed a little and still maintain structural integrity. The K member isnt all that heavy either, just had mine out with suspension attached to it with no motor, and was yanking it around pretty easy and also lifted it up onto a roller caddy to slid back under the car. You could go tube under there instead, but not that dramatic savings to be had other than nice clearance for all your other items, shaft, oil pan ect. Heaviest weight in these pigs is the glass. Wow on the back and front windows if you have ever had them out on a parts car we did. THATS where the weight is. Buttttt the windows are also an important structural part of our cars holding the twist of the top of car. But if you're caged or tube framed underneath, its not going to twist anyways, so go for it. Also on the trunk lid. They are heavy for what they need to be. I would definatley be interested in doing a carbon fiber trunk lid down the road project. There is alot of weight in the frame around the engine, but that's needed cause car is a uni body, type (unless you went tubed front end). hoods, are like the doors, they are lightweight to start with from the factory. Easily picked up by yourself. the rear K member is quite heavy and would definatley be nicer with tubed rear end in chromeoly, not mild steel. Sunroof weighs ALOT so better to look for a sunroof less car to drag with. But the car is pretty much very lightweight to point of being flimsy because its so thin (especially our anemic front fenders) cant even lean on them and they dent. its all the power accessories, door regulators and glass and front and back glass that make our cars pigs. we already have light weight aluminum upper and lower control arms, s threes not much you can take away but the accessories on these cars. Nope, im not loosing my carpet and cushy seats and AC. So if you're going balls to the wall, and converting it to a real drag car. Loose all accessories and non needed wiring harnesses and brackets for those accessories. And get lexan drag windows made up and Definately post pics. I would love to see how those look installed and how much they charge for them.
