Yes, I am talking about the perch half way up the strut. I parked my 06 next to an 05 and that perch is different between the two. 06 is just about flat, while the 05 has a cup effect to it.
Again, for the dampers, if the diameters do not match on the base, they will not fit. That is the big issue with the 06's, they have a larger strut mount opening in the knuckle...
so if your struts are 06 you will need an 06 spring. But what I understand some of the early 06 models still have the 05 suspension. So if you have an early 06 with the 05 suspension, the 2006 stuff will not work.
If the strut perches are different, then the shocks will not mount in the knuckles.
