Could those of you who have installed a 6-speed from a S4bt in your urS4, please provide some follow-up to the list. What exactly had to be done to the dowel to make it fit? What do you estimate to be the "out the door" cost? What are your revs at 60mph? 70mph? Overall, how are you liking it? TIA for your input, Greg J BIRA.ORG
