hes talking about when sliding all the weight is transferred to the direction of the slide, thats why tires squish when you turn its because the wright is transferred through inertia and you feel it as g forces, the harder a tire grips the more weight is on that side of the car, thats why performance tires have (weight) load ratings because of grip, gforces, and inertia

Still about 200lbs heavier than I would've liked... if the MX-5 could do it why can't Subie/Toyota?

*Rhetorical question - don't answer this* What's done is done.

Ok why is he talking about that?

Hmm, I hadn't considered the advertised weight being will a full tank of fuel. The math works out pretty close if that's the case, since gasoline is 6.1 lbs/gallon, adding 40 lbs to the scale weight makes sense, since both reports claim the car had about a half-tank of fuel.

USDM curb weight is reported with full fluid capacity.

Well that's what I get for not looking into it and solely relying on corner-weight scales.

Weight distribution is the result of many compromises. Primarily, minimized size/weight and +2 seating. They could have made the wheelbase longer with the front wheels shoved further forward relative to the engine/passenger compartment and made it 50/50, but there would be a size/weight penalty.

55/45 isn't that great, but at 2700 lb., I'll take it.

Would be cool if they also made a 2-seat sports car out of it on the same wheelbase, with the engine and front seats moved aft by 24" or so. 50/50 or better, no prob.

They are.

That is not what I'm talking about. That would add weight, take away rigidity, and doesn't move the engine and front-seaters aft.

Is it from all the new safety features that are put into new cars?

Stock early AP1 is ~2750 lb, AP2 ~2850 lb. This car has a back seat and weighs less.
When convertibles are made out of existing fixed-roof coupes, you get a ton of weight gain. This is not the case for dedicated roadsters like the Miata, Boxster (lighter than Cayman!), S2000. For them, there is no convertible weight penalty. Even the Corvette is only ~25 lb. heavier in convertible form.

A 1989 240SX weighed ~2650-2750 lb. The FR-S/BRZ are pretty much the modern incarnation of that car, and weigh the same. So, no weight gain from "new safety features". Or, rather, advances in design, materials, and fabrication techniques negate that.

2700 lb. is pretty much as light as could reasonably be expected, I consider it a success in that regard.

As much as I too would rather it were in the 2300-2500 lb. range...

Every single year from now until eternity you can expect cars to have stricter crash testing necessitating stronger, heavier sub frames because fat asses drive SUVs.

Read the article below and pray we get a Man's version of the greatest roadster ever made.
http://www.edmunds.com/mazda/mx-5-miata/history.html

"The 1990 Miata was truly tiny. With an 89.2-inch wheelbase and stretching out just 155.2 inches overall, the Miata was 16 inches shorter than Mazda's smallest sedan that year, the Protegé, and rode on a wheelbase 9.2 inches less expansive. Mazda made the Miata's small size a virtue. Everything about the car had a delightfully light touch. Instead of smothering the pavement under huge rubber, it relied on careful tuning of the double wishbone (front and rear) suspension to get the most out of modest P185/60HR14 tires. Power steering was an option, but the standard manual rack-and-pinion setup reacted instinctively to steering inputs and reported back even subtle details about what was going on with the tires."

"The biggest advantage of the Miata's small size was its feathery weight — just 2,116 pounds in base trim. Because light cars don't need big engines to achieve an entertaining power-to-weight ratio, the first Miata was powered by a 1.6-liter, dual-overhead cam, 16-valve inline four making a modest 116 horsepower."

it was more like the manual rack was the option. the car was designed to have power steering. the manual was an afterthought and the majority of miata owners like the feel of the powered unit more
