l left my old standard Se shocks on when fitting my eibach springs and now theyre getting a bit bouncey. I want to fit the 1BE spec sports shocks, but not go and spend a fortune. So ive been scanning all the normal new old stock clearouts and the last two letters keep differing of the part number. Do these mean anything or is it just a superseeded part numbers? 8e0413031 CK/CL/CP/DJ?
