Ran out of talent

5am this morning driving to work. completely empty road, no cars anywhere driving quick but not ballistic. cold and greasy roundabout = 180 degree spin Doh! why the hell did they put the engine there
Car was understeering very badly. I beleive this is the PDAS system working then snapped to oversteer. not the driving god I thought I was.
Funny thing is I was just thinking to myself how easy this car was to drive.
that will teach me.
Glad you and the car are ok...This is all part of the 911 learning process....better to perfect the art on a track/airfield though.
In these conditions, it best to drive smoothly,gentle with the throttle and steering...it sounds like you eased off in a panic on a turn and the back came round..
It is possible and very rewarding to drive a 2wd 911 on greasy roads, just don't expect the back to come out much, there is too much rear traction, which you can use to your advantage. Have fun..

I've been using my '85 3.2 non sport cab as my daily driver recently and have been surprised about just how much front end grip it generates in these greasy conditions - lovely to lean on that to gauge just how fast to go - being careful of course not to back off completely if it edges wide 
I'd quite forgotten how benign they can be if you treat them with respect.
The Caterham on the other hand, on ACB10s and not flat floored to my satisfaction, is a real handful as Iguana may have experienced recently

I don't think I lifted off the power. Car was understeering badly
(in teh inegra i would have given it more gas cos the lsd would have taken care of it)
I think as the car was understeering and went passed the apex I gave it more steering input and possibly gave it a little more power. Which I think is wahy it went from the understeer to oversteer. I must have gone passed the Pdas's limits.
A good learning experince I think. Will be more careful

For me, understeer can only ever mean one thing - that I'm cornering too fast for the conditions/capabilities of the car. Note the latter - my Mum's Datsun 120Y estate used to understeer at the slightest hint of any kink in the road....as I found out the hard way, straddling a neighbour's garden wall one evening....

yes certainly I was doing this. .
Combination of new car with very, very different handling characteristics. and cold greasy roads dont help. I wasnt going very fast luckily which is why I didnt do any damage.
Ive been lucky in the past having cars that basicaly drove themselves Imprezza, integra. I could have gone round this particular roundabout faster without any problems.
I recon it was diesel

If you're understeering the last thing you want to do is add more lock as it will not cause the car to turn in any more. Well not until the front wheels bite that is, at which point you're asking the rear wheels to develope a slip angle they have no chance of making while retaining grip and the rear starts to slide whether you lift, trail throttle or apply the gas. Your best bet is to apply a small amount of positive throttle and hope the rears develope some traction but if it's a big slip angle and the road is slippy the high polar moment of inertia means you'll spin no matter what ( obviously the more talent you have the more chance you have of catching it - so that counts me out and I've practiced this)
Pesty- I can't remember if yours is C2 or C4?
I do seem to remember tho that the car had 18's on it when you posted pics? I found 964s on 18's a bit twitcy even in nice dry conditions compared to 16s or 17s.
Obviously check tyre pressures 1st & what tyres are you running?
If C4- in standard form they can understeer a tad, a decent suspension kit- or say just decent springs like H&R or Eibach coupled to fressh standard shocks & a proper suspension align & set up they are far better.
Then again it is fecking slippy out there so you could hae just been pushing a bit too hard.

Hi pesty ! You already asked about airfield training, looks like you have got no excuse for not getting on first available carlimits day at North Weald. The only way to learn is by doing it with a great instructor...reading about it on the forum won't do it. As far as the 18 inch wheels go , I'd be inclined to stick with them and get the training in on worn tyres. Keep us posted .
Must be the season for it - happened to me too on NYE - greasy roundabout, 180 degress and 1 new rear 18" turbo required 
Oh well - shit happens!
