  1. You may want to look into getting your car aligned for

    track use. The stock set up would want to push. I

    would get the car up to 120-130MPH and slam on the brakes. I

    would then turn the wheel and accelerate. The car would still

    go straight. I had the car aligned for track use.

    The car is not perfect but it is a whole lot better. When I brake and

    then turn the car behaves.

    To make a real fast lap, I have to start the turn just a little bit before I am finishing

    braking and then accelerate thru the turn.

    I should not be giving out my racing secrets!!!

    Thanks for the racing secrets bro, I promise not to tell anyone ;)... Will find it difficult to get the car aligned for track use since in Lebanon we dont have a race track, so I dont think I can find someone to align it for track usre :).... Hopefully in the future we can get some investments together to get one started until then I'll have to do with what I have. I'll give my dealer a call and see if they can do such an alignment for me.

  2. I have played with the tire brand/pressure/nose lift/camber issue on a 2008 C2S for several months. The Pirelli's are very noisy and hard riding. After 7000 miles on the odometer I put them in the dumpster. The PSC2 from Michelin are far superior. Not only are they quieter and better riding, the adhesion is amazing. To get the car to drift now, I really have to push it. I keep the pressure slightly under spec, 34 fronts and 40 rears, Nitrogen only. I do have front end motion at speeds over 120 miles per hour, mostly vertical (some horizontal, I attribute most of this to thrust lift). Once I hit fifth gear on the S (126 MPH) the car settles a bit thru 150-155. Even then however, the car "feels" a little nervous at that speed. Like yourself, I remain a bit puzzled by the motion and will consider alignment adjustments as I am sure tire pressure/balance/size and brand are not the issue. Best of luck.

    After getting around 2,000 km on the tires and drifting a little in them (treading them out) the car does drive better. However I think I will do exactly what you did and throw them out after getting a few more thousand kilometers on them. Thanks a lot for the great input and advise.

  3. How are your tires? Mileage? Tire pressures? Wear?

    What are the road conditions like in your part of the World? Are the roads sloped for drainage/run-off?

    I have Pirelli Pzero Tires with only 2,000 km on them. 19 in rims. Front tires at 24 pressure and back tires 29 pressure. The roads suck in my city. Very uneven roads.

    I have driven other sports cars on the roads in my city and they aren't as un aligned as my porsche.

  4. I have a 2005 997 CS2. When I hit speeds above 120 km/h I feel the car does not go in a straight line and actually feel I have to force the steering wheel into staying in a straight line. The car doesn't crazy left and right but its just not straight and just floats a little to the left then a little to the right, thats when I have to intervene (the steering wheel actually gets heavy to a certain side even though obviously I have my hands on it). Sent it to the dealer and asked them to check it out. They said the wheel alignment is perfect and that the springs are good and that there is nothing wrong with the car.

    After getting it back I was starting to think that I was just being paranoid. A few days back I hit the high way and I could swear the car was not going in a straight line and I had to constantly keep it in a straight line.

    Some one told me it might be the control arm or something? any suggestions?

    Thanks

  5. Its a control arm...take it to your dealer they should know about it...

    I think its either a control arm or worn out mounts. Sent it to the dealership and they said nothing is wrong. The sound has almost completely stopped and the heaviness of the steering wheel is much less. If the problem persists I will send the car to the dealer and tell him to check out the mounts and the control arm.

    Thanks a lot guys, you have been very helpful.

  6. Thanks everyone for the replies. I sent the car to the dealer yesterday and they thoroughly checked the steering components and did a few test drives. They said everything is fine and normal. I do have new Pirelli Pzero's, might have to wait till I wear them out a little. The popping and cracking sounds are all gone and the dealer told me that the sounds might have been because of water on the steering components or from the change in weather (had the car in a dessert climate area for a while and now shipped it to Lebanon where the weather is Mediterranean). I guess if the dealer says everything is fine and tip top then I should be fine.

    Thanks guys,

  7. Hey,

    I have a:

    2005

    C2S

    Triptronic

    Blck on Blck w/ red stitching

    Blck 19" Porsche sports rims (loving them)

    My steering is a little weird. It started with a cranking or popping sound every time I would turn the steering wheel left or right. I took it to my dealer and after the mechanic turned the steering wheel left and right many times (made a lot of popping and cracking noises) he gave me an appointment to get a detailed check up for the steering but said its nothing very major and its safe to drive. When I was driving my car back home the steering wheel made the noise every time I turned it ( more often than before). The next day to my surprise the sound was gone. But then I noticed that when I drove on un even pavement/tarmac the steering wheel would naturally go right and left with the tarmac however the weird thing is that when the steering would go left or right because of the tarmac the steering would get heavy to which ever side and I would be forced to center it myself. I don't know if I'm explaining clearly, but its like the steering wheel wants to go left or right instead of centering. Funny thing is that when driving straight on good tarmac steering is perfect.

    Anyone have any idea what the problem could be.

    Ali
