Looks like you have standard suspension. I say that because you stated your part number is 235267xxxx when it actually is 33526757045.
I looked up your car in REAL.oem....http://www.realoem.com/bmw/showparts...41&hg=33&fg=45
They list the part number of strut/shocks for both standard and sport....for your car the sport rear shock part number is:33522282461...standard suspension rear shock # is : 33526757045
Standard strut part number is: 31306757043
Sport strut part number is: 31312282459
