Can I remove the headlight motors and headlights? They still pop up, though there is no switch to make them light up. I do have camera and traqmate system, with lexan vents in both doors. all a/c equip. is removed.
I have aluminum hood, no cat insulation or other insulation, gutted doors and removed emergency brakes. I can't find any ballast anywhere. TD 13 lb wheels and shaved tires. Still have brake shields and inner fenders (plastic). I don't know if the hardtop is factory or aftermarket. It's heavy either way, but I am not driving without it! Factory hooks will be removed. Thanks for all the comments.
Take a look in your right-rear frame rail make sure it's actually hollow Also, check under your battery make sure there's not a very, very substantial "mounting bracket" there. What battery is in the car. There's a 10+ pound difference in batteries.
Look behind the dash also. Consider what actually needs to be there. Make sure airbag sensors are gone as well as the associated wiring. Did your car come with power windows and power mirrors? EVERYTHING associated with those systems can be removed.
I also found at least 10 pounds of miscellaneous bracketry in the car. Replaced with zip-ties Definitely remove those brake shields as that's unsprung weight. Fender liners should go too.

Very true. When I bought my car, I didn't realize at first that the previous owner had wedged a generic Walmart full size battery in. Then being a cheapskate, I didn't want to replace it until it died. When it finally did, I pulled it out and weighed it. Sucker was 40 lbs. I replaced it with the proper miata battery which weighed only 19.7 lbs. So 20 lbs eliminated from the right rear of the car just like that! And extra weight outside of the wheel base is never a good thing!

I've read all this thread, and I still suspect a gremlin in this car. My origional SM (a 1991) was thirty pounds heavier, but my 1990 that (with a .095 cage w/ NASCAR bars on both sides, a fire bottle, radio, data loger, the big Koyo, SD exhaust, aluminum seat, a cool suit sysytem, 15 pounds of ballast and me (165 lbs) weighs in dry at ~2,270. If I get below 1/4 tank tank, I'm at risk! Admittedly, I pitched every bolt, and screw that wasn't required when I built mine, but there's gotta be something else going on to make a 1990 a piggie!

It is possible to roll them, but the screws around the edges will make pimples that stick out. Ask me how I know. Solution is to either shorten the screws with a hacksaw or just not roll them in so much. I run maximum trackwidth and haven't had any problems.

The plastic liners weigh next to nothing - leaving them in probably wouldn't make much difference in weight - but they're a pain in the ass. I doubt it makes much aero difference either - my just-made-it-up theory is that by removing the liner you allow the air to escape out the rear of the fender.
