I go to Black Forest pretty frequently,it's like 10 minutes from my work....I have APR STAGE 2+ and I was going to get the stage 2 insert, I mean, it's only a few dollars more....but after talking to Adam, who is the service manager there, he suggested the stage 1. I was told the stage 2 was a very stiff mount, and it would compromise the ride comfort. I trust them and until I go K04, I don't see a need. I'm very happy with my STAGE 1 BFI INSERT
