Loose steering at speed

The "aero" front spoiler is added on my car, the lower piece over the original bumper. You can see it where it's circled in Porsche-T's post. Are my clearance mesurements the same as other with Aero front bumpers? This piece may have not been installed 100% correctly, and could be causing trouble.
Also- as I said, the extra "front lower lip" is already integrated to this piece on my car, I cannot add one.
I'll have 18"s on it soon, but the 17" should not cause trouble. Maybe the all season Goodyear F1, but they seem pretty good for all season and are new.
Suspension seems fine, car handles well, doesn't pull. Anything in particular to check besides taking it in for an alignment?

I had the exact same experience. The dealer had put on new all-season Pilot Sports and I have to admit I didn't notice. The ride was like a rowboat on the high seas compared to the 18s. I mounted Dunlop snows on the 17s. Even they handle better than the all-seasons.

I'm voting for alignment. The lower lip (splitter) is actually a black rubber component and it looks like someone may have painted it to match the front bumper...which is fine. One of the issues with these cars at high speeds is that Porsche is mandated by US law to raise the front bumper to meet US regulations. I've always contended that it changes the dynamics of the engineering to make the car feel a little squirrely whenever it's not in PERFECT alignment. Most drivers who have switched to RoW suspensions have noted vast improvements in handlings...not to mention all the drivers who went with 3rd party adjustable suspensions.
