I know this is now probably the wrong thread to post this in, but I got my FSD/Weitec kit installed today. For the record, I have gone with the Weitec 30/00 setup which seems to be the way to go. I shortened my front bumpstops by 20mm, and at the same time replaced front strut mounts and also rear bump stops. I then for a full 4wheel alignment done (which was interesting!).
The difference is incredibly striking. I honestly didn't expect it to be such a transformation, but that's pretty much what it is. The car rides smoothly instead of crashing and jarring. The car sounds quieter too over bumps. It also turns into bends more positively. But the ride is still firm, and it doesn't float. So it's not that it's gone all soft and French on you, but it's just better. Vastly better. It now feels like a proper solid grown up car. These FSD shocks must be very good indeed. Do any cars have these on them out of the factory?
At some point I would like to swap out the OE Audi springs with some replacments, just to complete the job really, but until Weitec make a -10mm lowering spring for the rears only, I'll stick with what I've got.
The 4 wheel alignment showed up some rather eye-wateringly bad mis-alignments -my front right was -1degree out on camber! Everything is now decently aligned within spec, so hopefully the car should pull and stop in a straight line, and hopefully tyre wear should be relatively even.
This weekend I'll be doing a 300mile round trip mostly on motorways so I look forward to running the shocks in and seeing continued improvements!
