6MT GT with all options except appearance package and navigation.

I even have the spare tire in the trunk. Mazda did a good job keeping the weight down, especially when you look at the quality materials its made of.

... and the weight is?

Are you teasing us?

OK Pal, tell us the weight.

now THAT was funny huh?

Seriously it weighed 2925. I had 1/2 tank of gas.

An excellenty executed tease! Thanks for coming through with the goods.

On the weight; That's pretty cool - I was under the impression they weighed just over 3000 (wet).

I wonder how much of a weight difference there is between a fully loaded GT and something like a 1SP package (sans sunroof, nav, spare and all that stuff)

Cool.
Simon.

2925? That's it? Wow. Mine can't weigh more than 2800.......Cool info man....

2800? how? you did weight reduction?

Did you have helium in them tires? :)

? helium...

nah I was at the drag strip so I reduced them to 26 psi or so. everything was stock. Oh yea, I said 1/2 tank of gas, the needle was about 2.5 ticks below the 1/2 mark, in my experience that is closer to 1/2 tank, the gauge seems to read different then reality.

2925? cool i have the spare tire kit too. i thought it would weigh more with that.

yeah... the helium thing was a joke...

But maybe the blue paint is lighter than the other colors!!! Again... a joke. :)

Thanks for sharing this with us zerobanger. You got your car weighed at the strip? If so, do drag strips usually have weighing equipment? I'm not very familiar with the drag racing thing.

Yes tell us inquiring minds would like to know!

And it was weighed on a what?

Not disputing your numbers, just think it would be useful to hear.

Did the same thing a couple of days ago for my move to the east coast - 1/2 tank of gas 6MT GT = 2920. The weigh-in was on professional truck scales used at the supply dept at the base I'm transferring from.

Wow. I mean really. WOW.

I better tell the guys at the local truck weigh station (run by the state) to recalibrate (which they must do every day, by law).
My bone stock GT with appearance package, MT, NO SPARE KIT, a half tank and me (165 lbs wet) came out to 3180.
Mazda states the curb weight at 3029 (empty car with a full tank of gas), so I figured I was right on.

Hmmm...I had expected mine to weigh more as well, but when I saw another at the same weight I figured it must be true...I've since had my spare tire kit installed (but even then its shipping weight including packaging was only 43 lbs (kit w/ the tire included). Maybe gravity works differently out west? I'm actually headed to Maryland tomorrow. Maybe I'll see what it reads when I get there. :)

Coming here !?! ARE YOU CRAZY ?!?!
Why would you want to leave Cali to come here? Its freezing, our roads suck and gravity is way too strong here.:eek:

How long do you expect the drive to take?

Hi there,

I went to www.sacramentoraceway.com. They have two scales a digital scale and the normal old fashion scale , I dont know the technical names, but its the one where you set a base weight, in this case it was 2500, then you move the other weights to the right till it balances.

Its the same scale I weighed my 3rd gen about a year ago. My third gen weighed in at 2750 at the time. It was with the full exhaust including mid pipe which saved a good 60 lbs, no spare tire, etc. I know the weight is right on. My friend in is 02 trans am weighed after me 3550.

Hmm, that's wild.

Mine weighed on two truck scales at 3,090 and as they showed the same I thought they were right..

Mine is blue. Maybe they used lead paint..

That's going to hurt my GTech numbers for sure..

I'm wondering how accurate a truck scale would be for a 3000lb vehicle if the weights of interest are say, around 80,000 lbs?

Say you wanted to weigh 7 1/2 lbs of pastrami. A bathroom scale that's accurate to within a lb at 200 lbs might not be very useful for the task.

Good point Nubo.

Also, unless the cars are all weighed on the same scale, I wouldn't get too bent out of shape about any numbers one way or the other.

Excellent! I made a great decision getting the touring with black cloth then. I didn't care much for leather and I figured I'd get a little bit of a weight savings with no leather and all the electric options that come with the GT package. My butt stays pretty warm as it is.....

His was 2925, fully loaded luxo version...mine is just a 6 speed sport package. No sunroof, leather, power seats, spare tire, none of that. Have to save at least 125 lbs...don't you think?

A standard truck scale should be linear even at the lower weights (relative to a fully loaded truck's 72,000 pounds). The sensor is a pressure transducer that's actually interpreting the diameter of a strain-gauge. As the diameter of the reference wire decreases, the resistance along that circuit increases. The change in conductivity is read and converted to weight. It should be linear. The question that I can't address is how sensistive the transducer is. I should think that most would read in at least 1/1000th of the full scale with no problem. That would be 100 pound increments. Given that 100 pounds plus or minus could make a difference when weighing to determine freight charges (sizing a load), it wouldn't surprise me if the things were (are) more finely tuned than +/- 100 pounds....

Surely white paint would be the lightest?

;)

actually "his" is "mine" as "I" am the "his" you refer to with "his" "Luxoversion". LOL.

anyway, I highly doubt there is a 125 difference, probably more like 50-60 at most. Unless you have smaller wheels.

Mine did not have the Nav, I bet the nav stuff weighs 10-12 lbs.

Uhh..woops..didn't notice the name.

So... would mine weigh the lighest? Red Base 6-spd, no TCS, no DSC, no moonroof, no Nav, cloth seats, no HID, no body kit, etc. :p

But I do have a spoiler. Does anyone notice that the trunk door is heavy for its size? Kinda weirded me out the first time I opened an 8's trunk door. Are the retainers causing that virtual weight there? :confused:

Oh and, does anyone have an idea how heavy the hood is? I know that replacing a CF hood doesn't really affect much to the car's performance in daily-driving conditions. ;)

the hood, rear doors and rear hatch are aluminum. I dont see very much weight reduction being possible with the rx-8...lighter wheels, lighter battery...thats about it without gutting the interior (yuk).

This has been an interesting thread.

I as wondering though... It seems the stock wheels on the 8 are kinda heavy. I noted some really light units at Tire.com. Looks like I can save about 13lbs per wheel. Next, the flywheel can be replaced with a lighter unit, saving approximately 5lbs.

Total savings would be about 57lbs and should help handling and acceleration I would think.

What do you think?

the stock wheels are around 19 lbs each i think. Maybe im wrong.

the stock 18's are not that heavy including the tires something like 23-25lbs.. not to shabby... but canzoomer has a nice set of 17's that I bet shave a 1/4 sec off the 1/4 mile...

Stock wheels are 21 lbs.
Stock tires are about 24 lbs.

I weighed them. Separately

You found some 8 lb wheels? In 18" ??

Show me please.

Stock wheels are 21 lbs each
Volk Racing forged wheels in 18" x 7 are 17 lbs each.
OZ Chrono Evolution are 18.5 lbs each

SSR Competition (forged lightweight) are 15 lbs each, and are the lightest I could find..

I weighed my car in at 3082 pounds with a full tank of gas, me in it, and a gt fully loaded with navi with out the appearance package

CZ,

ref my previous posting ....

I thought I had read that our 18 wheels were 28lbs each...

Others have corrected me.

Based on your statement of 21Lbs per wheel, the 15lb replacement would only result in a 24lb overall weight savings. Not much in the way of overall weight savings. Would 6lbs per wheel make a difference in handling and acelleration?

Still learning

No sweat.

The weight saving we are talking about here is un-sprung weight. in terms of the responsiveness of the shcoks and suspension for handling, it could be quite significant.
In TRACK times.
On the street the difference would probably be barely noticeable at best.

In terms of acceleration the difference is tiny.

However, having said that, if I were to decide to buy new wheels for my RX-8 I would buy 17's.
Adding the weight as the smallest factor, the lowering of the drive ratio as the biggest, and the savings in cost as the middle factor,I think that 17's are a smarter choice.
Maybe they would not look as "cool" but they would certainly improve the performance.
And lowering the car the 1/2" this results in also does good things for handling..

The only thing worse then going to maryland is going to NJ....

Did you here the joke about my last girlfriend? She said "kiss me where it stinks" so i DROVE HER TO JERSEY...

I weighted my RX8 today...MT, GT no nav gear, full fuel, spare tire, but nothing else in the trunk or in the car.

Measured car weight on all four tires at the same time using four individual scales, one under each tire. Total weight came to right at 2960 pounds. Interestingly enough the weight on each tire came in at 740 pounds. Talk about balanced weight distribution!

Scales were recently calibrated to plus or minus 1%.

I think this validates what my rx-8's weight came to. with a 1/2 tank of gas and the exact same package as you (even the spare tire) it was 2925. Since a gallon of fuel is 6-7 lbs, thats about 42-50 lbs, putting us about the same weight. Good to know.

Mine was 2950. gas unknown. then it was 3260 with all my stuff for moving to NV.

Yeah, I heard the navigation system weighs something like 400 lbs - the screen the DVD the wiring harness, the great big antenna. :D

(just kidding)

Glad to hear the news.

IIRC, gas weighs about 7lbs/gallon... and EPA curb weights are with a full tank of gas...
