not to be off topic, but i believe a member on the forum weighted their car at a "truck weight" station here in california. his car came out to be around 2870, and he doesnt have any packages what-so-ever, just the base manual.

Now, I wouldn't be surprised if that were off. A truck scale would have a range of accuracy that would be much higher than the weight of a car. It would be like trying to measure the weight of a paper clip on the scale that I used. It wouldn't be accurate. (I'm exaggerating, obviously, but you get the point.)

However, maybe the weight WAS right, and he had very little gas in it.

If I recall correctly, Mazda claims 50-50 weight distribution when there are two people in the car, so this may explain it?

I hear you zoom!

I'll bet it is damn near 50:50 if you are accelerating like you are supposed to. The weight shift will probably equalize it.

the new 3rd gen miata is around 52/48 and with 2 150lb adults in the car, it comes out to almost 50/50 exacaly.

zoom is right, the 50/50 for this car is just 'nearly', there really isnt much handling differnece with 52/48. the weight difference can easily be shifted with the throtle.

Also, something else to think about, does the rx8 in japan have any differnt crash structures, such as front crush bumper or anything that may be different on the US spec version?

Maby you shoul change to a lighter-weight engine oil....5w20 is to heavy.

When I installed my REVi and Ram Air Duct I did notice my Australian spec car has a different front crush bumper compared to the US spec that came with the Racing Beat instruction manual. I had to make some mmodifications to keep the Ram Air Tube firmly in place. I also noticed that the CAI is very flushed with the airbox air entry point. I've also read some people using some sort of foam to seal the gap in the US.

However, it's very superficial to make any difference in weight distribution.

When mazda quote cars its with a passenger in it...

Unfortunately they design it for small Japanese drivers. When we test drove the mx-5 at zoom-zoom live the guy said the car was designed for perfect 50/50 with 150lbs person driving. two passenger is even better then one he said.

get a battery relocation kit theres nothing wrong with a bit of weight towards the back....except it maybe scary when breaking hard and turn ins. lol like a couple pounds would mean that much but on a miata its gram strategy and every bit helps.

Ya that's wierd... In my RX-8 Brochure it says:
Weight distribution %(fr/rr) 48/52

Well I'm sure his scale has a margin od error. Besides he never stated what scale and how he did it.

No scientific proof. If he's not using a truck scal or a scale that measures scrap then I don't know what he is using.

How in the hell you weigh the front vs the rear? Drive the car on half the scale?

It was a 4 WHEEL scale. That means there were 4 scales, in reality, and the individual wheel weights are displayed digitally, as well as the overall weight, accurate to the 1/2 kg. I was using this scale for vehicle testing at work. It is owned by one of the largest auto manufacturers in the country (without specifying who I work for). I'll give you a hint, though... I might as well be one of the folks in the lab coats in the Mazda commercials

And it also adds up - if you indeed weigh about 160lbs, that's an impressive scale to be able to measure that on top of a 3000lb offset. It must be quite accurate.

BTW, I'd be curious to see if bmw's have the same situation. My 330 coupe is supposedly 50:50 but a 60lb sandtube in the back made a nice positive difference on snow handling.

I'm more interested in total weight than distribution at this point. We already know the car handles quite well around a track, removing or adding a few lbs. here or there isn't going to ruin the balance of the car.

FWIW I've had my Rx8 conner weighed and adjusted before, and after installation of a set of Tien Coilovers. Sorry, the shops notes don't indicate where the fuel level was; and the car has had a rear trailer hitch installed to pull a track trailer with spares tire sets etc. for track days ~

Before:

LF 784 RF 788 Front total - 1,572l
LR 780 RR 764 Rear total - 1,544
3,116 total

After Tien Coilover install & adjustments:
LF 768 RF 768 Front total - 1,536
LR 748 RR 762 Rear total - 1,510
3,046 total

an additional data point. In my case, the Rx8's front to rear weight distribution seems to be within 30 lbs. The rear trailer hitch probably adds @ 25 to 30 additional pounds all hung out over the rear overhang. HTH someone.

DOMINION

Hummmm... Well Mazda said the new MX-5 has 50/50 with 2 people in it. Can that be it?

mlx8

Depends.

Is J-Lo one of the two people?
