Ask Emilio, he's done it. My recollection was that it took at least that much off.

Did you get much from undercoating? I wonder if it's true you can get 30 lbs from acid dipping a bare tub, and a re-paint. Seems like a good thing to do if you're stripping to bare tub.
Factory NA Shell...................466 lbs Carbon NA Shell...................Approx 82 lbs |

What radiator, front brakes, and what have you done for weight reduction? That's basically stock weight isn't it?

180 lb driver
+/- full tank of gas ~2300lbs without driver 52/48 split I've since removed around 100 lbs of plastic bumpers and misc. sound deadening. No fancy digital scale photo. Not bad for having a full interior still. https://www.miataturbo.net/attachmen...ine=1421128367 |

Stripped, Intercooled Rotrex, caged track car with 1/2 tank of fuel.
Roof, wing and 10" wheels with 225 NT01's. https://www.miataturbo.net/attachmen...ine=1421135809 |
Madness is a very good name for that car. I hope to take a ride in it some day. Sub 2k with that setup has to be a joy.

That is with 250 lb driver so 2085 very light on fuel. heavy godspeed radiator and Vibrant intercooler Id guess those two items are at least 25lbs heavier than stock. turbo system is not really that light eather. long runner manifold is like 18lbs. no top, 14 lb seats. brakes are 11.75" rotors with dynapro calipers (mini kit) and 11.44" rears. still lighter than stock.

Didn't realize that was with driver. What is your seat position like? We extended our controls (5'10" and 5'6" drivers) and were able to move our driving position back about 5". Not sure if that's legal for you. Definitely lighter seats are available. One piece or two piece rotors? I just purchased 11.75 rotors and there is a range from about 9lbs to 15lbs per side. Also, looks like you have some room to corner jack that thing a little bit for better balance.

No passengers seat. That's where the fuel tank lives. |
I'm lighter with more power and currently have a passenger seat. :)

WI think 180A of weight in drivers seat for corner weighting and 1/2 tank.
https://www.miataturbo.net/attachmen...1&d=1421287173 No driver. https://www.miataturbo.net/attachmen...1&d=1421287173 |
interesting how weight distributions on miatas seems to vary between 51% and 55% to the front. seems like quite a swing.
|
Depends on where you've removed and added weight. Can't imagine any other reason.
|
track cars with a cage roll bar and more safety gear more fuel and less interior seem to be more balanced I guess. when I take all the track stuff out of my track car to convert to an autocross car it becomes nose heavy. Its faster around an autocross course even though it is nose heavy without all the track stuff though.

Semi gutted 91 with roll bar and hard top (naturally aspirated setup at the moment). 170 lb driver. Shooting to get the chassis under 2000lbs. That will be a stretch tho since I want to add more chassis stiffening mods.
with driver and 1/2 tank gas https://www.miataturbo.net/attachmen...ine=1421552562 w/o driver and 1/2 tank gas https://www.miataturbo.net/attachmen...ine=1421552562 cross weights (have alignment specs there just for quick reference) https://www.miataturbo.net/attachmen...ine=1421552562 |
