Coverage and how to read this overview
Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Just got my first boxster yesterday. 99 2.5 tip with 87k.
It has been lowered, ride was not firm as with most that are. Coming home at 50-60 mph plus the rear end feels at times like it is skating or on ice is the best way to describe. I already found a used set of oem springs to put back on it as i know that chopping springs is no good? Me and a nearby shop looker underneath and all control arms, bushings, and everything visible looks good? Does this symptom sound like something caused by chopping springs? It has to be lowered close to 2 inches, maybe more? Rides soft with no noises???? Tires are brand new also.
Those rear wheels just look wrong. Way too far inside the fender for stock. I'm guessing they are front wheels, put on the back. Spacers are good, but verify wheel size and fitment.
Get confirmation on the exact size, but I think the stock 17" wheels are 7" wide in front with the rears 8.5".
Here's a site I go to for some wheel info, but it's incomplete and its too dark and cold outside for me to go verify mine.

Here's one of mine on M030 (slightly lowered suspension) with stock 17s in a 'mirrored' perspective. See the difference in back? that's more than I'd expect from just cut springs.
My guess is that who ever lowered it didn't use adjustable rear control arms (as The Radium King mentioned), and now you have a lot of toe-out, and that can cause scary wandering. They probably didn't do any kind of alignment at all, so all the camber and toe settings are way out of range.
I hope you didn't pay much for that particular Boxster! You have some work to do to get it driving correctly, and to get the correct rear wheels.
This is the correct size wheels.
Fit the proper springs and correct rear wheels/tires and then see how it handles. Should be about 1000% better.
Where did you buy this car and how much did you pay?
I got it from a tiny lot in chesnee SC for $6500 out the door. Looked all over the southeast and was the best for the money I found. He was asking $8995. He lost money and just wanted to clear room. He showed me his reciept that he paid $6k at the dealer auction and put a new convertible motor, tires, and battery. First time I ever left a dealer and didnt feel violated!
How do you know the springs were chopped? You've definitely got something funky going on, but those two statements above don't sound like chopped springs. You chop 2" out of a spring and that spring rate will be out the roof; you'll be bouncing your kidneys around like crazy.
You sure they didn't use a lowering spring? A lowering spring, poorly installed without fixing the geometry will, as others have mentioned, give you substantial toe-out,w which will give the vague feeling in the rear, as you describe.
You've definitely got something wonky going on, as evidenced by the wheels, as well.

No way to know for sure until I get them out of there. But had a shop look and did not see any evidence of any other way other than springs chopped. Its too low and plan on installing factory springs back. I would have thought if they used lowering springs would be stiffer ride also? Had a car before lowered on springs, and the ride doesnt feel like it? I plan on checking wheel sizes tomorrow, betting some front and rears may be reversed?? Will be sure to update!
Its hard to tell, but I don't think that rear tires are on the front. If that was the case, the fronts would stick out more.
This is what 255/40/17 tires on an 8.5" wheel look like on the front (and same size on rear)...
Well, i have 3 7 inch wheels and one 8.5! Wth!! Well time to pick up a new wheel, and at least can sell the other. The left rear did have a 7” wheel on it!
