Stability can equal handling (if its not stable, how can it handle). Hmm, how do you measure stability on an absolute scale? Sure its subjective till we all go for a drive and sit down over coffee and discuss the drive experience.
I have done what what u did in the merc with the mx5 many times- same results as yours - car shdders in understeer, back off, and back to u-ey turn. Cars do not flip or overturn unless you hit something like a kerb. Sure they will skid/slide, any car will do that.
Cars with short w-b and lightness, then the mini/sub-compacts of <1000-1300cc will have the same effect of 'weight-lessness', with tires that lasts... now these are scary cars to fool around in.
I've had a couple of spin-outs at PG in an MX5 at 140kmph in semi-wet/dry conditions: a sign of instability due to its lightweight? - no!.... just applying/releasing the gas at wrong times. This will happen to any RWD, even FWD if its fast enough.
Anyway... its just that i'm an MX5 fan, and just wanted to give the MX5 a chance in terms of what it can really do. Sure, i agree on less overhead protection - a price to pay for that kind of roll-over fear. Even SUV's roll over too ( classic case of 'stable' but cannot handle.) Rex's are stable.. and can handle too, right?
Its about road conditions and the experience to do the right thing on the road.
No flames pls... just defending a cute little nice car (that some pple do not understand) that is getting bad press.
Ah but I have to disagree with your view. 1stly, any car expert will tell u that some stability will have to be sacrificed for a car to handle. How would an MX5's stability compare to say a Merc S class?
Let me ask u. U say u have done the same thing I did many times. What speeds did u do them at? PM me on this. Not something we should be discussing openly.
2ndly stability in a car is also measure by how likely it is to spin when u make an error. Some cars are more forgiving, some cars less so. The fact is that an MX5 does need some familiarity with it. Granted, once u know the car, the drive is rewarding, no doubt. U have to be clear about this, we're discussing the characteristics of a car from an abstract point of view, and its impact on the cause of the accident. Nobody is blaming the car itself. I understand that as an MX5 owner u feela certain sense of pride about the car, but u have to be objective about things.
Anyways, since u're comparing a WRX, well honestly, a WRX understeers at 1st, until u can use the power to tease the rear out. Cars like the EVO n GT-R, depend heavily on electric trickery to affect their handling and stability. When we talk about cars which still depend heavily on mechanical ability alone for its handling, a car which handles is always less stable compared to 'normal' cars. Do note that we're not saying that everytime u step on the gas or turn the wheel the MX5 spins. No in this instance, if the stability of a normal family car is say, a 10, then an MX5 would be a 7.5 to 8. More care is required, but not to the extent that u have to slip it in neutral and let it roll along by itself.
Anyways, like I said, I speak from past experiences from racing. I know that if I want my vehicle to handle better, I have to sacrifice stability. This golden rule of thumb goes all the way up to even formula 1 cars. if its a car, it generally cannot escape this rule unless u have a car choke full of electronic wizardry. Thats why the really fast F1 drivers, are the ones who can cope with oversteer. An oversteery car allows them to turn in at a higher speed, sharper, faster, IF they can deal with the oversteer. Drivers like Michael Schumacher and Kimi Raikkonen drives like this. Drivers like David Coulthard, Jenson Button, are fast drivers but they prefer stable cars, which is why they're quick, but not Kimi-quick. They depend on a smooth driving style to be fast because their car is more stable, but less responsive to handling inputs.
Since time immemorable, I've read about car magazine journos talking about the trade-off between handling and stability. Nothing escapes the golden rules of automotive engineering.
