Yes, robiasu is correct so be careful. The B6s that I have are not made in a short version for a car with 3rd row seating or air springs in the rear so I would need the taller rear mounts to run them because I have a 3rd row. If you don’t (have a 3rd row or rear airbags) you already have the correct top mounts in the rear for the B6s. Incidentally, the fsds (special active konis) also are not made in a “shorter” version for my 3rd row setup but are for the standard “taller” mount.
(standard setup)tall mounts + tall(er) shocks=OK/good=short mounts + short(er) shocks(rear airbag setup)
Short shocks+tall mounts & tall shocks + short mounts = bad.
Don’t let this nonsense confuse you. Figure out what you have (real OEM) by vin and stick with parts that cross to those OEM numbers. If there’s a need to do something “off label”, like robinasu (and soon myself) have done, you can wade into the minutiae.
I’m glad to actually be able to contribute instead of just asking for help like I usually do.
