A while back my manual 997 rear end stepped out slightly, exiting a tight bend on a B road, a bit damp & giving it a bit of gas. I was slightly un nerved as this never happened before even in the wet. Anyway, put it to the back of my mind. Now a few days ago exiting a roundabout, new tarmac and again slightly damp conditions it fish tailed left and right while I was going ( I thought pretty straight) although accelerating fairly hard from 2nd to 3rd). Now definitely un nerved. Plenty of tread on tyres. New bushes, drop links and arms on rear suspension recently, All OPC and Still under warranty. Any thoughts appreciated.

what tyres?, even wear on them? also check pressures.
bridgestone Potenza. 5 at the back 6 at the front. All even. I had checked the pressure too. They are over 2 years old. Never had a problem in any road conditions before.

Thanks for all the responses. Just never happened before when pushing it. It was not a quick left and a right. It really felt like I lost it. As I say un nerving. Maybe take up the advice of some instruction.

Its probably just snotty roads. Limits of grip are changing constantly and the easiest way of breaking grip is to ask the car to accellerate and turn at the same time - especially from low speeds. Its also the easiest situation to recover from and helps make motoring journalists look like heros. Its a little more difficult to deal with oversteer caused only by lateral forces - which unforunatley can have to opposite effect on motoring journalists. Either way, you will have just learned a valuable lesson in exactly where the grip levels are on that particular day. Just bank the grip info and dont exceed them again on that day. The following day there may be 10% more grip at the exact same place but conditions may appear the same. On a busy road there are all sorts of factors effecting grip.
Understand what you are saying but what un nerved me i'm 99% sure i had it pointing straight after leaving the roundabout (up a slight hill). Had the car 2 years now and amazed how it handled. Maybe i was just getting a bit over confident, it is my first Porsche and had never had a rear wheel drive before.

What looks straight and flat to you may not appear that way to your rear wheels. Cambers, unevenness, poor grip etc can all mess with stability.

If you've not done a Porsche Experience course they are well worth doing. For a while at least you'll be more relaxed with finding your car suddenly sideways. In fact I have one I received as a gift that I cannot use and could let you have cheaply (if Porsche allows re-assignment that is).
That's very nice of you if you wish to PM the details. Thanks.
