Are they not limited outside the us? Cause 270 km/h is just under 170 mph, 20 mph over the limiter.
Yes there is no speed limit.It can make about 280..282, but you need a looong strаight road.And ot starts to vibrate.You feel that you have a massage... :P P.S.I'm interested where are U from???
I'm in mid-missouri... Chances are your tires are the problem at that speed. Even z rated tires are often shit about 150 (240 km/h), you need to make sure your tires are designed for both the weight of the 430 and speeds in excess of 180 (~290 km/h) Load index I think is 95 but your owners manual should specify. And driving that fast is stupid on road find a closed track, because if something breaks at that speed it's catastrophic failure.
there is a possibility that the universal joints (u-joints) are no good causing the vibration, but this would normally cause the vibration at lower speeds (around 65 or 70 mph) but it could be a sign that they are starting to go, or if it is the all wheel drive model the transmission could be getting some play up and down where the front shafts go in.. this would also cause a vibration. does it only happen during acceleration? or does it happen even when you coast? is it all wheel drive?
