New GT3 owner

[oversteer]

I just purchased a 2005 GT3 and was looking for advice on the handling of the car. It wants to change lanes when I accelerate, feels like the front end is always hunting especially at higher speeds. Visually the front looks like it has toe out but that is hard to eye. I bought it from the Porsche dealer who did the 100 point inspection but I'm guessing they did not check the alignment. Does this problem sound consistent with an alignment issue? Any info would be appreciated thanks.

Big part, your tires

I just changes mine and it made a world of difference.

Hi Oversteer. Congrats on your new GT3. Our cars are extremely sensitive to tires and alignment. You should check both soon. I'd try the alignment first. I'd recommend you start with stock alignment first to get the feel of the car as it was designed. You can always tweek it later if you want. When it's up on the rack, assure that nothing is loose in the suspension. Check the anti-roll bar drop link nuts...they are known for loosening. Read the before/after alignment printout to see what it was and how it's changed. Assure the ride height is withing stock specs. I run the toe in in the rear toward the more-toed-in end of the range. You will get other advice from others...but, I recommend experiencing the car as it was designed first. I run the front toe-in within the spec range too. Assure the camber is close, side to side.

Then assure you don't have excess wear on the inside edge of the front or rear tires. Inside shoulder wear, especially in the front, can make the front darty. I get a very conservative alignment for the street and then get a separate track alignment for the track. A track alignment on the street can be not-fun and will wear your inside tire shoulders prematurely. I can get 2-3 alignments for the price of one new rear tire.

Let us know what you find out.

Thanks for the link and information, I will post my findings

I had the alignment done and it was all messed up, the rear had toe in on one side and toe out on the other, same with the front. The camber was off on three corners. It feels easy to drive now!
