Welcome and great find. I bought mine in 09 with 24,700 miles.
I just got the Rancho shocks and they don't seem as stiff as the OEM ones. Was thinking I should have gone Bilsteins but sounds like wasp1971 is saying no. sounds like OEM might be the ticket.
I'll throw In a tip. Rattles at highway speed that sound like your sunroof is going to blow off is an easy fix. It's your window molding coming loose. Take it off on each side and re-silicone it to get rid of the rattles.
This is the best forum I've found, although I haven't hung out at x club much. People here are great. Even the new guys that come along are nice.
Enjoy!
