Hmmm,
the "new" rims are actually original cayman 17" rims. The only thing was the offset for the rear are further out. The front offset for the front is the same. I had all 4 rims tested without tires - spun on a balancing machine without tyres. All straight.
The front tires are brand new Michellin Pilot Sport 3 (not N specs). I do have a mismatch between front and rear tires - the rears are 2yr old Aspec Db. Had not changed them yet as thread >95% and there was no stock for the tire size I needed.
No spacers - had bad experience with them on my 944.
I had checked my tire pressure and the rears were 2 psi off. Got that fixed and the car now feels more fluid and goes around corners pretty balanced in the dry. What a difference the tire pressure makes. But unfortunately vibration is still there. I still have to take it easy in the wet, but that's prob due to the aspect db tires - those things have no grip in the wet.
Looks like I got to find a Hunter Road Force machine locally, heard there one.
Or hopefully when I get the suspension swapped out they'll find a cracked top suspension mount or knocking strut !!!! ha ha...
