Bad handling 996.

I am experiencing bad handling on my 996. It feels like "white lining" but it happens when I accelerate or at speed. It is quite a fight to keep it on the black stuff sometimes. I have checked the tyre pressures and tread depth and both are OK. Any ideas please?
 
Get a proper geo done.

If the tyres are all OK, then its likely the geo.

It can transform a car.

+1 and check all linkages/bushes at the same time
 
When I first got mine it did the same.

Tyre pressures should be 36f / 44 r. Putting mine right made it a bit better.

What tread depth have you got? How old are the tyres?

Both these factors will make a big difference. At 3mm and/or if tyres are 4+ years old they will be well past their best.

If your tyres are newer than 4 years old, with more than 3mm and set at 36/44 then a GEO check is your next step.

Good luck :thumb:

Thanks for your quick response.... Geo?? am I being an air head here but what is a geo please and who or what type of business would carry it out? Thanks

Have a read here

or key GEO into the 'Search Forum' box.

iirc You're based on a Scottish Island so this may mean a trip to the mainland for you. :nooo: A decent tyre company might be able to do a basic check for you but it would need a sports car specialist (preferably one familiar with 911s) to check it properly.

NB: If you do go to the trouble of bringing it over it would definitely be worth having it done at a Porsche specialist.

Just to expand slightly on what you've already been told:
Your car's handling is partly dependant on its wheels (or more specifically, its tyres) being positioned "consistently" in relation to the car on the one hand and the road surface on the other. Any "slop" anywhere in the suspension system will introduce randomness into the car's interaction with the road (=poor handling), which is why you were advised above to have bushes and linkages checked for wear (play) or damage.

The next step after ensuring there is no slop in the system is to have the suspension geometry checked and (usually necessary) adjusted so that the "geometric" relationship between car/tyres/road surface not only remains consistent but is also optimised for your driving conditions.
This, put simply, involves measuring the relative positions of the car's wheels to each other on a test rig and realigning them as necessary to correspond to a set of prescribed values, generally those recommended by the car's manufacturer for a specific model.

Ideally, both of the above jobs should be carried out by a workshop which really knows Porsches, so that the mechanic doing the work is very familiar with your car's specific suspension system and its idiosyncrasies.

If you mention where you are located, someone here will probably be able to recommend a suitable specialist workshop.
 
1st : Check all suspension components, bushes....etc .
2nd: Geometry check ( Tracking). Very important. Need to be spot on.
When everything is right , it will change the car !

Tracking need to be check from time to time on Porsche especially. The rear set up is sensitive and can be off by hitting a pothole , even a small one....
 
I vouch for the geo. It transformed my car. It is rock stable and sure-footed and goes as if it's on rails. Not cheap - I had it done at an indie and I did question why the price difference with that at ATS/Kwik Fit.

These are specialist cars and need appropriate attention from a specialist and someone who knows the cars inside out and the driving style you have.

Also support having all bushes and linkages checked for any wear or sloppiness. Geo will not correct sloppy bushes and linkages.
 
Ditto the above, I would jack it up and see if you can feel any play from the suspension, and failing that get the geometry checked.
 
Hi and thank you for all the kind replies, its great to know we are not alone when help and advise is needed. I live on isle of Skye (there is a bridge so no probs in getting over to see us!) I do travel back to civilasation occasionally, (well other parts of Scotland!!) and England, so if anyone can recommend a specialist or two to carry out the geo test and servicing I can choose/ contact that would be great. Thanks again
 
Interesting thread I believe my 996.2 is in need of a geo check as handling currently not spot on can anÅ·one recommend a god indie in south east London (Bromley) area
 
I can recommend RPM on the Herts/Beds borders - transformed my 997 and was worth every penny.

T8996C4 has used project nine for a geo with good results (he can tell you more). I'm thinking of going there too in the next few weeks for the same.
