Do I have the right wheels and tires?

Hi, guys!! Haven't checked in for a few days and appreciate the recent replies.

I called a local Porsche dealership today and spoke with the service manager. We discussed at length the many theories you all have offered up. He suggested that rather than assume the problem lies with the questionable wheel size and/or the usage of used tires there may be frame damage undetectable by the naked eye.

That being said, I will be taking the "Boxster From Hell" to a friend's body shop to be put on a frame rack. I believe it's called a Star-A-Liner. Apparently, it will be a lengthy process, as it measures every aspect of the vehicle and can actually straighten out any sort of accident induced frame damage.

Honestly, I would rather it be a case of the rims being too big, as the thought of what it costs to straighten out a frame makes me wish my mid-life crisis Porsche purchase never transpired!! Well...almost. I truly do love the car

I will report back when I get the results.

If your tires are wearing considerably from the inside out, you may have excessive negative camber. I run neg 2.5 degrees in the rear and do not wear out the tires; however, I put less than 3k miles a year on the car.

Hello everyone...

Latest update on my car is I STILL HAVE THE SAME PROBLEM!!! Or at least a variation of it.

The car was put on a body alignment machine...it's straight as an arrow.

I replaced a rear control arm and a trailing rod that had supposedly bad ball joints with brand new Porsche parts.

I replaced ALL FOUR tires with NEW...yes NEW Michelin Pilots, 235/35/19 on the front and 275/35/19 in the rear.

Had the wheels balanced. Got a four-wheel alignment.

So now, rather than the rear end squirrel about, the steering wheel takes on a life of it's own when I remove my hands by turning side to side as if a one-eyed drunk driver were behind the wheel!!

I give up!! I love this car and do not want to sell it. I just can't keep throwing money away though... What's going on with this car?? And why can't any of the so-called qualified techs figure it out??

One more thing...

I had the conical lug bolts removed, and almost all of the heads were shredded. They were the original factory bolts, and were not for the 19' rims that were put on prior to my ownership.

I installed brand new cone lug bolts. The only result is that they look better than the old ones, yet I had the painstaking task of cleaning and painting the holes where the factory bolts scraped.

Just trying to narrow down any and all possibilities regarding the suspension and wheels...
