I experience this wobbling at the rear, not on dry surface, but on snow and ice. I can drive in 60 mph and the rear is going from side to side all the time and I have to adjust with the steering wheel all the time. I am driving MS tyres, Dunlop wintersport M3, 225/40/18 and 265/35/18.

It doesn't affect me so much, but I wonder if it affects the handling in dry and on track.

It's been rumored that Porsche will change the laws of Psychics in 09. Until then you will have to reduce your speeds on ice and snow.

Take a look at the inside half of your back tires. This is typical of tires that have little or no tread on the inside half.

The tyres are new so that shouldn't be the problem.

60 MPH shuld be possible to drive even at snow and ice :-)

Is this a joke post? The rear is sliding on snow and ice?

Wow...

I can't see out of my car when I drive at 60mph. This happens in thick fog.

Same here, plus I get light-headed when the engine is on and I stick my nose and mouth in the exhaust and breathe heavily.

Here's the deal... The compound on those tires is very soft and the tread is very deep when new. No matter what, even on dry roads, M&S tires are going to wiggle at the rear when you put some power down.

You are too nice, Ron... LOL

There were some issues with loose sway bars ( if we were talking about dry ground) that caused instability issues, easily fixed, I think with longer or different bolts, and the obvious tightening.
I've also heard that a virus in the microsoft-based PSMS communicating with the MAC-based On-board NAV graphics computer system caused handling problems

All the problems were with the Microsoft piece, the Mac Nav is of course perfect in every way!

I wonder if we can use the BMW in-car radar system in the Porsche?

I've never actually seen it myself, but I see BMWs which must be using it, doing 80-90 in think fog in SoCal, without even having their fog lights on!!!

Or do you get a module fitted in your head when you buy a BMW which dissables your ability to make safe & rational driving decisions!

NNH

I'm fairly sure that BMWs' foglights must be on the same inoperative fuse as their turn signals.

NNH

I agree. The issue clearly relates to a loose nut.
