Oh one note about the PSB poly subframe bushings, I had a fitment issue.
On the forward two bushings of the rear subframe, the bushing goes around two locator nubs (one per bushing) to center the subframe. The inner diameter of the metal insert for the poly bushing was a fraction of a mm smaller than the nub. This required me to ream out two of the inserts (the rear two bushings don't use locators). Not a major deal in the end of the day, but a PITA not knowing going in. I am not sure if it was just my set or my car (03), but it's something to be aware of.
Here is a link to another post of mine that has pictures
