I'm on stock struts at the moment, but I have done a crapload of research on this over the last two years. . .
The AGXs are not proper 05 fitment, they're specific to 02/03. The topmount attachment and springs are different. If you intend to do both springs and struts in tandem, your best solution would be to do topmounts as well, and buy everything in 03 fitment (03 springs, 03 struts, and 03 topmounts). A full swap fits up just fine.
There is a mod available that will allow 03 struts to bolt up to 05 topmounts, but there has been evidence to show that this is less than ideal and could cause problems down the road.
Currently there is nothing available for 05 that is comparable to the AGXs. Matter of fact, there's next to nothing available in the way of struts, period. Coilovers are all the rage with those who want to be (or seem) hardcore, so that's where most companies are focusing.
Jeremy, I double-checked boxer4's listing for those Ohlins struts, and they have them listed for 02-06. Know what that means. . .
