Found this post.. Am looking into the Air Suspension which Harald mentions, which is used as an additional shock absorber. I changed the Shocks from the Original Bilstens to Avo's and that compounded the spring problem. Given the lack of Bump stop in the AVO, can this be rectified by adding a Spring Assist as Rog did, or do you need both?
It seems odd you have Morgan specialists selling and promoting Avo rear shocks for post 2006 4 seaters if they just make things worse.
