    Loving my car but have question.

    After 3 years in a porsche turbo i see a difference in the drive of this car. At higher highway speeds i notice a "light" feeling in the steering wheel, almost like i have a tire going flat or something. Feel like the car is slightly weavingProbably just a feel kind of thing but it is a little concerning when it happens. Any one else?

    Ps: i did lower my tire pressure to the 2 person limit listed in the manual.

    How old is the car? It could be down to a number of things; road surface, tyre wear and/or brand or incorrect suspension geometry. I would try driving it at a similar speed on a different road and see how it feels.

    Odd. All of my R8s have felt firmly planted at high speeds.

    What pressures are you running?

    I have always run 36 psi cold on the street (usually ends up with about 38 psi when warmed up).

    Are you still running the worthless P-Zeros and how much wear are you seeing?

    OP you might be over inflated.. 36/36 is good.

    Yes, I agree with lowering the pressure. I had the same problem when I went to the specs in the door sticker. Much improved going back to 36psi.

    I have the same problem. Switched from magnetic ride to v10 plus suspension and the problem remained. Got new pilot super sports to replace Bridgestone s04, and the problem remained. Messed with all sorts of pressures, again the problem still remains. I'm stumped at to what it can be. It's actually a very unsettling and unstable feeling.

    I hit 153 mph yesterday and it felt pretty solid. I am running the higher pressures on the door.

    Re: Loving my car but have question.

    Could it possibly be that the track rod ends need adjusting? My gf's Range Rover Sport's steering was horrible straight from the factory. We had to take it to the dealers twice to get them to investigate properly. I loathed driving it but once they'd adjusted these it was a different car. Not necessarily saying that's what's wrong with yours but it does sound vaguely similar.

    Could it be tramlining? Depending on the road surface, I've felt something similar from time-to-time with my gen 1.

    Have all the suspension bushings inspected.
    It's rare that they wear but it can happen.
    Check all suspension bolts too. If loose a bolt can oval the hole it resides in and allow unwanted movement.

    These cars are very solid so something being even slightly loose could cause what you're feeling.
