Ideas identifying a wobble of sorts

[Paul]

Check the alignment, especially the toe.

+2 on the alignment. Too much caster can cause a shopping cart wheel effect. It could be too much air in the tires or a loose steering rack ( mounting hardware).

This was my car. I had it aligned to stock specs right before sending it down to Stilov in TX last summer to be sure it was good. The shop said everything aligned perfectly

I did replace the stabilizer links and some bushings, but not the shocks. At the mileage it's at (111k when I sold it), she's probably ready for shocks. The Bilstein HD's are recommended as replacements for street use with stock springs.

New OE bushings?

yeah, for the swaybars. Was chasing down a clunk.

I read this thread as was having similar noises. I bought an engine mount I was going to fit and still am. However I thought I would replace all 4 tyres and see if that would do anything to help.

I don't think people appreciate what a set of new tyres can do. Ok I still have the odd noise but the thud and clanking I had going over speed bumps or any slight mark in the road has gone.

New tyres= less noise and creeks ;-)

I'd ammend that to say "new good tyres"

My Boxster is running the cheapest Chinese tyres I could find at the moment as she'll be shredding them the next few weekends getting used to the car and new suspension/alignment
Next month they'll be terrible .
A good street tyre will stay good throughout most of its tread range .
These cheap Chinese ones will be terrible and shaking after 1mm of wear
There is also a remarkable difference between tirenoise even on good tyres .
I took the shredded oe tires off my carrera and fitted some hankkook rs-3 and it sounded like all 4 wheel bearings had took a dump while the wheels were off .
