I'm getting H&R's and AGX's for about $500. Got the H&R's on ebay for 140 shipped from this guy:
ebay seller
The AGX's on ebay go for about 370 shipped.
Thats's 510 total. Worth it to me since the AGX's are a much better strut/shock than the hp's and I know nothing about their springs.
I should note that the H&R's technically violate the warranty on AGX's, but I'm hoping my the 1.6" was for Z's and that its a little less on cars with the 2.2.
