My street 83 is down to 2600 pounds. I didn't do much, but I did start with one of the lightest versions. Stock, she weighed 2800 pounds. After an A/C delete, late tube headers, lightweight battery, no spare, and a few other things, she was down to 2600.

I've been toying around with dropping another couple hundred pounds. Remove rear seats, replace carpet with lightweight stuff. Some other random interior stuff. Fiberglass hood, front fenders, and fiberwerks front and rear bumpers should do it.

Rear seat is most likely next for me, anyone sell a cheap shelf or something to replace the seat?

I don't know if someone has already mentioned these:

The bursch test pipe weighs a lot less than the cat.
A smaller-gel battery.

Good call!

What do the rear seats weigh? Usually this is only worth a couple pounds so I end up leaving them in. But heck, it's not like a real person can fit back there anyway! lol.

rear seat BACK (not the bottom cushions) in my car weighed 20 pounds. it took all of about 10 minutes to unbolt it out of the car - real easy. the spare tire weighed 30+ pounds - that's an easy 55 pounds of weight (including the jack) without removing any carpeting.

I never really thought of removing the rear seat back until a few months ago. Took less than 10 minutes like jospeh said. I never have anyone in those back seats anyway...my car is always a 2-seater. I also removed the spare tire and jack for a few weeks...i was actually able to start getting the rear tires to spin a little in the rain, wasnt possible with all the extra weight in the back.

I would imagine its also beneficial (marginally probably) to remove the rear seat back..10 pounds off a higher point in the car. Gotta lower the center of gravity a few millimeters .

Yeah, every little bit helps. A pound here and a pound there can really add up over time.

Mazda made the 3rd-gen RX-7 super light by requesting each engineer in charge of a part o lose a single gram from his part. The result was hundreds of pounds in weight savings. I was thinking about buying non-critical nuts & bolts in bulk out of titanium or alloy.

"Don't forget the rubber sound deadner inside the fenders. There must be 30+ pounds of this stuff! "

Are you talking about rubber stuff that's sprayed all over the underside of the car? Has to be some way of removing it bulk. Like freezing with a cold-spray of some sort and chipping or grinding it off in large chunks.

Overall my car is pretty light for a street car. Ive noticed better turn in response as well as better accel.

I think My next project is to replace the rear bumper with a AIR one, that should get rid of a bit more. Also MSDS Headers.

Enjoy good luck making your car a bit leaner.-chris

Some notes

Hoods don't weight 75#. 45-50 tops. But at least you pulling weight from the correct end of the car...

Stock seats are heavy! my old sport seats weighed #55 each. Their replacments weighed #17 each.

Remove all the carpeting. (wait, I'm not done yet)
Take all the sound deading padding out. Then scrape the crap down to bare metal (like Ski did on the track car project)
Ski track car thread
Then for a street car, put back the carpeting and enjoy about 50# savings. An added plus is you get to hear any of those nasty noises better too!

Do the same to the bottom of the car as mentioned before and you'll save another #50+.

Ok, I'm contradicting my own spreadsheet, but hey, why not.

Does anyone have pics of what it looks like with the rear seats removed? (Looking from the front of the car into the back seat area)

Thanks!
