Approx 7000 kms on them. 1 rear perch is slightly damaged but works 100%. The part that is damaged is the allen slot for adjustment, I find it easier to adjust by taking the spring out anyways, but if you are slamming the car no need to worry about it.
The rear shocks also have JTD aluminium strut mounts. They are stronger and not as prone to failure as the OEMs.
If I recall correctly the p/n is 29480-2 which should fit all E46 except Xi
