Cous3 Mmmm sounds like oil or derv on the road to make it let go so easily Parthiban, especially at relatively low speed and a manouvre you've probably done and dealt with 100s of times. Won't hurt to get Tony cast an eye over it though.

Yeah still need to have it looked at, but to be honest the car's been feeling a lot better now, not really sure what could have changed but I haven't had any funny moments lately.

So Tony therefore thinks the problem has to be with the tyres, similar to what happened with Anees and some others, his thinking is that the Eagle F1 Asymmetrics have some sort of problem. He thinks the sidewalls are not standing up to what is required, and the fact this problem has developed as the weather got colder means that it's likely a problem with the tyre compound not getting up to the right temperature in normal driving.
Therefore I plan to take it easy through the winter months, and see if it gets better when the weather warms up again (because the tyres have been so great otherwise). If not I might need to change tyres as everyone else has had to..........
And obviously I now retract all my previous recommendations of the F1As until we can prove whether or not it's the tyres at fault :thumbdown:

Well had the car in at WIM over the weekend, and not the best news. Put the car through the geo, all settings are still fine, and after looking over the rear end there was no visible damage.

Hope you can get this sorted out ok.Yeah it does sound like an odd problem with a road car, but Anees had a very similar problem with the F1As on his BMW, as did dazz32 on his IS........although I think they were having problems when it was warm as well though so not exactly the same, but the root cause in all instances were the tyres.
And yeah, given those experiences, as soon as Tony looked at the geo setup and the rear suspension and all, he could only conclude that it had to be the tyres.
2tongues At least there is a dim light at the end of the tunnel.Yeah I suppose it's not too bad considering, and he said it's only the rear that will need replacing if at all, so I could just use the current rears as spares for the front and just buy two new tyres for the rear

Then, a few days later, i nearly span it on a roundabout, doing nothing silly either, got a nice little rush, but put it down to going over the white lines on a wet road.
Since then it has tried to bite me a couple of times, always wet, not icy, not standing water just the normal wet scottish roads.
Took it to my mechanic, put it up on the ramp, nothing loose, or broken, everything looks as it should be, now i'm loosing confidence in it, find myself driving like my mum round corners now, with my ass cheeks clenched waiting for something to happen.
Hate throwing away tyres with good tread, but i think this is my problem as i feel ok about "chucking it in" on dry roads.

Been reading this thread for a while now with interest, not that i was having the same probs, but when i got home from offshore this time the wife told me the car had been stepping out on her a number of times, so much so she was not driving it, Checked the tyres, loads of tread, pressure wasn't so far off what it should be, made them all 35psi and i took it out and pushed it a bit (dry road), got home and told her not to be so stupid.

Seems I'm not the only one then, that's an almost identical description to what's going on with mine - as steve said above, what tyres are you on?
