> I agree with the adage, but brute force seems to win in this specific case. Even though it's the lightest model made, my Miata only gets 0.82g on the skidpad

The current ND2 (2019+) Miata regularly pulls ~0.95 stock in magazine tests, almost identical to your model 3 Performance number.

You can exceed 0.95 and get ~1 on an ND Miata with slightly wider than OEM tires (still on stock rims) and a little more negative camber, which is widely done to the car by the enthusiast community. Similarly, you can get more out of your very own NA (1990) Miata with simple tire/alignment changes, even more with cheap new sway bars or springs etc.

The ND2 is a ~1070kg car.

To use a more fitting Lotus example here, the ~900kg Lotus Elise (50% of the weight of the Model 3 Performance) pulls 1g when tested by Car and Driver:

Yes and you can modify the Model 3 to increase cornering ability, but like in the case of the Miata it means increased tire wear, worse comfort, and worse mileage. Not to mention money.

My point was simply that even if you know vehicle A is twice as heavy as vehicle B, you don’t know for sure which one is faster in the turns.

> increased tire wear, worse comfort, and worse mileage… Not to mention money

It literally means none of this to change a miata as I described - we are talking a single degree of camber here not a race car. An alignment is normal maintenance - no change in price - and tires stay the same price if you go up a single size, so if you do this when getting new tires anyway it costs essentially nothing.

It’s a minor camber change (done at a standard alignment as normal, no extra special bits - just ask tech nicely). The tires will last just as long for your driving style and gas mileage unaffected. Comfort unchanged - no spring, damper or tire pressure changes.

The point this all makes is simple factors beyond weight have a huge bearing on constant lateral load car will sustain, to the point it’s almost pointless to compare weight and max corner load. You will never see car enthusiasts comparing weights of their cars and arguing in favour of more weight, almost ever. This entire comparison is pretty odd. No one who knows what they are talking about is going to question the classic Colin Chapman quote because physics didn’t change since his death - the concept of same car but lighter was faster in the 60s and 70s, and is still faster round a circuit today. It’s why race cars set faster lap times as the fuel tank depletes, which proves the point beyond doubt.

If you haven’t had a good alignment done to your NA recently get it done and don’t be scared of small adjustments, they won’t ruin anything - it does quite the opposite! - and the numbers that work great for all miatas are insanely well documented online. Steering feel will thank you for it. It’s the first thing I will have done to any generation of miata - they all benefit a lot, and usually arrive from factory not very accurately setup at all - you will see this when you have first alignment done and brand new car has initial numbers all over the place.

I’ve owned and maintained multiple examples of all four generations of the car over the last 20 years - a precision alignment with a touch more camber/toe is one of the easiest, best and cheapest (100-150 dollars typically in major US city) things you can do to the car - the miata is all about that steering feel which is easily corrupted.
