08-09-2016, 01:20 AM #21I have increased my PSI from 35 to 38 for last few days and covered a mixture of roads and the handling has improved. As Steve said, it is all experimental based on your car setup.

steviewevie I think you just need to experiment and see what works well for you Parthiban. My car is handling great with 38psi, but I've got TTE springs and uprated ARBs, so what works well for me might not be the same for you.
Yeah totally agree, just wanted to see whether anyone else was experiencing the same thing
But yes both our cars will have very different handling characteristics anyway so isn't a direct comparison

Turning right at about 20mph, squeezed the throttle a bit harder than normal to make the turn as there was a car approaching - because of this the car snatched 1st instead of staying in 2nd.
Normally this isn't a problem, bit of wheelspin, TC picks it up and there's no drama except maybe a slight step out. This morning though the rear end just snapped and in an instant I was pointing head on at the traffic island at the junction - it was a quick armful of opposite lock that saved me from heading straight into the bollard.........
It's possible there was some oil down that caused it, but given the car has been behaving so weirdly recently I just don't know. What I don't get is how unpredictable the car is - sometimes it feels totally planted, and sometimes it just snaps!
I'm going to get the car to Tony as soon as I can now as I need to have it checked over - could it be the tyres? Considering swapping the tyres front to back to see if the problem persists, is it ok to do that?
Are there any other problems it could be? Could I have suspension damage or something that is unsettling the car?

Ok I've definitely got a problem, had a massive moment this morning that has got me a little concerned.

Could be some sort of suspension damage but I would expect WIM to be able to pick up that sort of thing.
Was it damp this morning though ? Could just be bad luck and another greasy surface ?

15-09-2016, 02:50 AM #24Getting the car to WIM sounds like a good plan. Also I don't see that it can hurt swapping the front tyres to the back, as long as they have a similar amount of grip - don't swap the fronts to the back if the fronts have less tread left than the rears though.

Yeah it was wet, but this was still very unexpected behaviour - a little wiggle is fine, a full on tank slapper (when I wasn't being silly) was a real shock.
Also, I'm not sure if you'll agree, but I find the IS200 quite progressive when it loses grip, and is very easy to catch as it generally comes round quite slowly. It's very out of character for it to snap so instantly, I can't actually remember it ever happening before and needing such a quick reaction to prevent disaster.

The IS200 doesn't generally lose grip so easily which is why I'm so concerned about my car at the mo........was there some mud down on the road or something?

D**m that does look like a big off, glad it wasn't a serious crash and hope no damage was done to the car. Did you have your foot down hard?

I've only had the back of the car step out once, on a greasy roundabout, but as you say it came round quite slowly and I easily caught it.

16-09-2016, 03:29 AM #28Have you tried swapping your tyres front to rear yet Parthiban ? Have you still got plenty of tread left ?

Not yet, will do it at the weekend if I have time. That's what's confusing though, there's plenty of tread and it's all nice and even wear.

No damage to the bodywork then from heading into the bushes? That's really lucky!

Yep, thankfully you can just chalk it up to a lesson learned - you don't want to spin the wheel too much in the opposite direction, just half to one turn the other way to correct the slide.
