Time to rip out the old bags?

[TheClaw]

I started a thread over here about http://www.xoutpost.com/bmw-sav-foru...rut-issue.html and I'm wondering if it's time to replace the entire system.

The left front strut was replaced 20,000 miles ago (2 years) with a BMW part, the right side replaced 6 months later with a strut from Arnott. I'm getting some sag on the right side already. I thought maybe I had a leak but a local shop tells me the the strut is bad. I'm pretty surprised the Arnott strut is leaking already.

Do I just bite the bullet and replace the whole system with coil overs?
