Basically speaking,if I was to over-take,the situation comes about anywhere from  the 120 to 140kph,gets a bit hairy not knowing where its gonna drift.I had the same situation occur fairly recently again but with no drift.I cant really explain!No signs of rain either!

What were you overtaking? trucks? Sounds like air pressure to me.. Does it happen at those speeds when you're not overtaking anything? Edited by Mal

Tempting....oh so tempting.....(temptation resisted dammit)

However. I'm with the tramlining. Gotta be to do with the rubber whether its aligment, pressures, wear size or type or a combination.

Has all the signs.

Having taken delivery of an XR6T myself recently (last weekend.. sweeeeeet) I'm wondering if you have been driving another car with steering that is less direct???

Having a 2000 Challenger 4x4 (4Sale if anyone's interested PM) the steering response is like chalk and cheese. I'm going from a tyre with about 150mm of sidewall, soft suspension to a low profile tyre and sportier suspension and as expected the steering feels like a go cart compared to the Challenger. I know that mrs speed limiter (Wife) also noticed the sudden change of direction compare with the normal ride.

Hope this helps....????

In the Ghia I was overtaking trucks at 170 (you know, to be sure everything is working etc...) on the way to Adelaide, and yes, it does get floaty. But, even though I was within cm of touching the dirt on the side of the road, I managed to keep it strait without any real hasle. If you are complaining that its getting floaty at about 140 with an XR6t, which is lower (and therefore must have a lower lift coefficient with less air travelling under the car), and with more rubber, then the car is a little big for you atm.... Get used to it.

Find a track and practice keeping the thing strait at 150 plus.... Once you get above that, you best be concentrating because that's when the dynamics of the car changes. Also, 180 is where the fun starts :).

On that note, has anyone here wondered how much of an effect having an underbody tray with a tapered rear (as in, the rear of the undertray tapers up into the guard, which helps reduce lift) would have?

It might be something worth taking a look at because Aerodynamics plays a fairly large role at speeds over 90km/h. After 90 it actually starts taking significant amounts of power to keep the car moving against the wind. I'm sure there is an equation for this.

that's why your car is most efficient at 80 - 90 (check your trip computer next time at these speeds, you should be able to get about 7L/100km).

Meh, anyways.... Its too early, my brain hasn't turned on yet (I'm on a uni holiday for the week; vice chancelors week) so this post most likely wont make any sense and will be rank with spelling and/or huge grammatical errors....

I reckon its a problem with the spacer between the drivers seat and the steering wheel.

Tramlining normaly pushes you in one direction, not several. Sounds like it could be air pressure with the limited description.

I'm with Trumpy - loose nut behind the wheel ...

If a person can't tell the difference between drifting, tramlining, or wind buffeting he has a definite driving disability. Just hope he doesn't cross my path on the highway.

Come on guys...cut the guy some slack. He obviously has asked a question he needs an answer to.

I want to know why the bonnet was replaced. Who replaces a bonnet? I've had my bonnet for 2 years and there's nothing wrong with it. :spoton: Couple of chips maybe.........but it still works.

Was it a new car........has it been in a bingle and thrown something outta whack.....

...........Or maybe it is that loose nut....... :kissmy:
