This is actually the first time I've contacted you. But thanks for the answer.I think I talked to you on the phone, but yes that will be what you need to make that work for the 06+ SI transmission.
Thanks! Another option I may explore.Yes, you will need a speed signal converter.
You have a few options for the shifter; You can use our new Z3 specific shifter and shifter cables and leave the stock mechanism in, or you can change it and use the 02-04 shifter and cables.
