I am considering changing the set up on the rear of my S7 from spring and dampers to coil overs. What open length would I require for the change and what spring poundage would be suitable.

 

Any advice would be appreciated.

Just to add to this question as I'm also interested in the answers, if changing to coilovers do they mount in the standard shock position without modification?

If Sierra rear end used, they fit into the original Spring wells using square shaped u brackets.

On my S3 they have a bracket to the rear of the A arm and go up to an angle bolted to the side under the arch
Something like 10.5 closed 16 open with a bush bottom mount and rod upper

I believe the Exmo has the same rear end as the s7 and I did this recently. The coilover I used was 13" open and 9" closed. This is what it looked like.....

Hi guys, thanks for the replies.Thanks steamer for the pics, that looks like exactly what i am trying to do. I suppose that if i did not have the spacer between the coil over mounting and the angle bracket at the top I could use a longer unit. What make of coil over are you using and what springs do you have on them ?

I fitted AVO to my series 3, cost £205 direct from AVO in 2005. Much better than the original RHE supplied ones.

Another photo, a bit out of focus! Spacers added either side of the top shock mounting to stop end float. Reinforcing plates are fitted to the outside and inside of the boot to sandwich the weak stainless side panels to give added strength and stop flexing.
