Thanks for the replies.

Ausmpower, I think I remember reading that your car has/had the 226 option as well. Would you be able to tell me what colour markings are on your rear springs? Also do you know the boge/sachs or bmw part number for the rear shock that you have on yours (assuming you have sachs/boge shocks on it)?
I just want to check to see if the old ones were the right ones. They did have 88 stamped on them, so I assume they are original.

Cheers
