The other day I was looking at a guy's e28 M5 and really liked his UUC short shift kit ( I just messed with it in a parling lot. Didn't drive it.). I was interested in putting one in my e28 M5 as well, but I wanted to hear how others felt about them. Do you like the way they feel, do they put more strain on the tranny, ect. Any information or commets welcome.
