I own a 2006 Cayman S and I love it. I have a slight vibration in the steering wheel at speeds of 60 and over. All 4 wheels were balanced and wheels were check for dents. No dents and car still has a slight vibration. If I hold the steering wheel tight, it doesn't brate. Any sugestions?::
Does it go away after a while? I feel the same thing sometimes. I attribute it to flat spots in my tires after it has been parked in my garage for a couple of days. My 996 was the same.
This is what I did to correct a similar issue when I first got the car. I took the wheels off and cleaned off the cosmoline which had accumulated a lot of dirt in a random pattern then I remounted the wheels and made sure that they were torqued to factory specs. That cured the vibration for me.
Also this can occur if the car isn't run for a period of time and it can take several miles driving to eliminate any "flat spots".
Have you road-force balanced the wheels?? - a standard balance may not be good enough.
Also, I had similar problems unless I am very careful when mounting the wheels.
I would try, jacking it up, loosening the wheel bolts, re-centering the wheel and re-tightening the bolts. It does not take much for the wheels to get a little off center.
If wheels/tire balance check out fine, another possibility might be one of your toe-links may be loose. That is the problem I have right now and wheels/tires were balance recently. My left side toe-link attachment on the wheel side has play in it, it appears that it is worn down, should be a warranty replacement, we'll see as I am taking the car to dealer tomorrow.
There are few indicators: 1- besides vibration on the wheel, the car may be slightly wondering while on traveling on a straight line as if it is tramelining all the time, 2- while cornering hard, especially on Interstate ramps, the car may feel little edgy or nervous, and 3- if you jack the car up, try to shake the wheel holding it from the sides and see if there is any play and potentially clicking sounds from behind the wheel.
I have a 2007 Cayman S with 19" tires. I have only had it for a couple of weeks so I'm not sure I should be commenting, i.e., I don't know the car well enough to know what is "normal". I have the same vibrating/tramlining problem at high speeds. Past cars included a 2003 M3 and a 2005 Boxster. Both of these cars were rock solid at high speeds. I'm thinking the wheels need balancing. Can't hurt. Might help. What do you think?
Certainly would not hurt; try road-force balancing if you can, I had good results with that.
I have been complaining to the dealer about this for 2 years now and they havent beeen able to figure it out. They never mentioned toe links, but I will call them as soon as I am finished writing this.
They blamed my wheels the first time, I got a brand new set of BBS -road force balanced- it still vibrated.
they blamed the wheels again.
I have a set of new VE wheels on it now, it still vibrates, they are still blaming the wheels.
We will see what they say...
I thought I was imagining things when I felt this a few weeks ago, after returning from vacation and taking a drive the first 30 minutes or so I was noticing minor vibrations, its all cleared up after regular driving now.
On a slightly different note, in about a month the CS may be going into its first winter storage, Cover/Maintainer are purchased, but was wondering if you guys have any PSI reccomendations to help alleviate flat spots during the winter non driving months? Just inflate as high as the tires are rated for?
Blitzkrieg, your Owner's Manual recommends 58 psi and moving the vehicle slightly every four weeks for tire protection while stored as well as other useful tips (see Storing your Porsche in the OM). Also there is a very good thread on winter storage here that if you haven't read will be helpful.
Thanks Beez and Santa Fe, also is this the thread :

you were referring to about winter storage?
Yep and this one as well:
