welp heres my take on this...

no fucking way a m5 sedan BMW autobahn cruiser can withstand 1.4 lateral g's on a 200foot diameter skidpad....

see the lat g ratings we see on our cars, like .88 for 240sx, is how many g's it can withstand constantly going around the same circle. its not so much of a test to see how hard u can make the car turn, its more of a test to see what mph u can hold it at. Just because they say it does .88 doesn't mean it can't put a greater force on your car or body.

The IRL cars are rated at 1.4g constant....which is fucking GOOD, insanely good...as in something most of us have never felt. HOWEVER, I use IRL cars to make my point for a good reason, one day I was watching a IRL race and they had those on screen graphics up, that show if they are using throttle, RPM's, speed etc..... this one also had lateral g's...which were exceeding 3 lateral g's... yes thats 3 g's. Some of the reasons why they are so much higher then what they rate its skidpad specification is... speed(the higher your speed the easier it is to induce higher G's), banking of track, tire is probably hotter, aerodynamics are taking more of an effect, but the greatest reason is that this is not a sustained manuever like a skidpad test is. They run the car at the absolute limit right through the middle of the corner, where the brakes and acceleration are not using as much of the tires grip.. this allows them to throw the car into the corner REALLY hard but by the time it reaches its maximum grip and is ready to plow through the grandstands, the turn straightens out into the back stretch or what have you... they couldn't keep up that 3 g's constantly, so thats not its skidpad rating........

maybe BMW has seen the new car have a load of 1.4 g's through a hard corner and a computer recorded that, sort of like a r34 gtr can...

come on lets get serious here, a IRL car says 1.4 lat g's... that is a purpose built race chassis out of strong materials that is about 4x lighter then a M5..... lets say M5 weighs 2 tons, a IRL car weighs in at around a half a ton... a IRL car is using much harder suspension springs and dampening, not to mention the expensive gummy slicks they use, while the BMW is forced to comply with the rich old people who want a smooth fast ride..lets face it u don't see many 20 year olds driving $85,000 cars, and the DOT approved tires the BMW must use that also work in wet conditions.

I would say that a BMW m5 getting a constant 1.4 lateral G skidpad rating, when u compare to something that can actually do 1.4 g's sustained..., is about 99.9% impossible
