H&R Springs + KYB AGX Struts are supposed to be a really good combination. In case you didn't know, the 1999-2005 Pontiac Grand Am shared the same chassis as the Alero and is almost identical when it comes to mechanical parts... If you're looking for parts on your Alero and can't find anything, try searching for Grand Am parts.
