Z4 Coupe 3.0si Sport rear springs part number?

[mackie1]

Well a few days after I got my Z4 one of the rear springs has snapped!

It's being repaired under warranty by the supplying dealer but since they aren't a BMW dealer (the deal in used Porsches primarily) I just wanted to make sure they got the right part. Am I right in thinking that the SE and Sport have different springs? Would anyone happen to know the BMW part number for the (I assume lower and stiffer) Sport springs? Thanks in advance

Cheers. I did a bit more searching and made a request through here: http://www.cooper-bmw-parts.co.uk/browse-parts/

They checked my VIN and came back with 33536761925 as the part number.
