RAS floating feeling
Hi,
I’ve had my car a couple of months and recently been doing some motorway driving. There is a distinct sensation that the rear end is floating around whilst at higher speeds in a straight line.
Is this normal as I feel like I don’t have full control of the car (it’s actually quite unnerving) and I have to slow right down or cling to the steering wheel.
Low speeds on country roads I might add are great but it’s knocking my confidence in the car.

Thanks,
Tyre pressure’s are 42psi front and 48psi rear.
It could be the whole car that feels a bit floaty but I put it down to the RAS as it’s the first car I’ve had with it.
kinda feels like it’s on casters lol.

Try 35 front and 39 rear. Then adjust (down 1 PSI) from there. Don't let the tires get above 40 hot. So, let's say you hammer it tomorrow, and the rear tires go to 41 (starting from 39)....bleed out another 1 PSI and try again tomorrow. As air temps continue to rise with the new upcoming driving season, you'll bleed more air out. Then come fall 2020, you start adding air back come October, on.

It’s a tire pressure issue. It can happen on any car. With a high performance car, the impact can be greater.
