Should my 996TT pull me all over the road?
Discussion
Hello all,
I have the above and to be frank I'm getting pi##ed off with the constant battle to keep the car on the road. When driving on a bumpy road the steering pulls all over the place.
I really have very little confidence in the car. I have checked pressures 46 R(hot) and 36 F (hot)and as I have recently purchased it from an OPC they assure me that the alignment has been done as part of their preparation.
Is there something wrong or 'do they all do that sir?'
Also, can any other owners comment on interior rattles? Are they "normal?"
I recently had a new Cayenne out on demo and I am really tempted to jump ship!
Any advice appreciated!

I would start with cold tyre pressures, set to something like 33 F & 38R and then if that made no difference, I would get the car up in the air & get the front lower arms checked for wear. It is most probably the arm/ball joint but eliminate the simple things first.
As for the sqeeks ???

No, not expecxted behaviour.
They may have done a basic alignment, but not a full geometric check. I bet they only did the tracking; 911s are much more complex than that as the gempetry is so variable.
Worn bushes is possible, as is tyres or tyre pressures.
Go and test drive another - preferably at the same dealership so they can compare.

Tyres - check all correct sizes & offsets (sounds daft I know) with all same tyre make/N number on each corner. Pressures - 36fr/44r are the Porsche guidelines.
Geometry - Done recently - if not get it done (£180 ish from a good specialist) according to my specialist Turbo's can be thrown out easily and this should be done every 12 momths.
Suspension bits - Mine looks like it needs 4x new lower suspension arms - not cheap but not a fortune to replace. The bushes have worn and this has thrown the geo out & caused uneven tyre wear on my tyres - and also thrown the handling out.
Quick look on a ramp and you can see all 4 arm bushes and see if they are worn. Also - you can hear a creak from inside the car when they are worn which can be a giveaway.
Rattles - well mine has a windscreen rattle (new winscreen a few months ago), also one coming from where I wired in a Road Angel (can sort that) and also when the sunroof is open that rattles like a b1tch too.

When I first got my 996tt I ran it at the recomended pressures (BTW it's 44 at the rear not 46) and it was pretty skittish. Having played about with a few different pressures and different tyres I find mine is best on MPS2's with 33psi in the front and 39psi at the back.(Cold)
If changing the pressures doesn't help then see the above advice on Geo's and suspension bits.

What other Porsches have you driven?They all have an 'acquired 'taste to the way they drive which you either love or hate..imo the steering is superb on smooth surfaces(996 onwards better than anything)..however on poor bumpy roads very scary actually.I wouldnt waste too much money sorting out tyres,pressures,or geometry etc...its just the way they are and unlikely your car is so badly set-up.I have the above and to be frank I'm getting pi##ed off with the constant battle to keep the car on the road.

I had a C4S before and loved it! Just not quick enough IMHO. Supermono the tyres are Continental's??
Agreed re the C4S great car but really needs more power. Given that you have had a C4S previously I wouldn't have thought that your turbo should feel significantly less planted than a C4S. I'd go down the getting it looked at route.

Sleep envy I have to grip the wheel pretty hard as if I don't it's all over the show..
that could be part of the problem - when I bought my previous 993 I'd do that at it made it worse as I was tensingI found a more relaxed grip helped loads but it does sound like your geometry could do with a check just to be sure

Indeed, let's do that now. If you have a right angled triangle with the hypotenuse of 12 units at 32 degrees from the horizontal, what's the tangent of the opposite side's angle???SM
