well I don't have long term review as I sold my 323Ci. but I was very happy with my Meyle HD ca and cabs. not to mention they have a long warranty.
Meyle HB cabs are not filled with oil. but they are full rubber for a sportier feel.
if you want the most comfort in the switch, go oil filled. but the non-oil filled for the record were not harsh at all imho
if you have 100K on these and think they are still good I think you're in for a surprise. i am sure you will feel and instant upgrade in turn in response to avoid beagles no matter what you go with
