Seabass,
I was reading up on the Suspension FAQ Thread and wanted to thank you for all you input. I just picked up a 2005 Outback LL Bean (3.0R) which makes it my 4th Subaru. I definitely experience a lot rear end wobble/instability when hitting 75+ on the interstate and hitting road bumps or dealing with wind.
Based on my observation of the Suspension FAQ Thread, I think I'm going to go ahead and do the following upgrades on the 2005 Outback:
Rallitek Rear Sway Bar (and Upgraded End Links and Mounting Brackets)
KYB GR-2 Rear Strut Assembly (341276,

Any input you have is appreciated.
