actually, based on the e46Fanatics threads, the mechanical parking lock will not work, but BMW incorporates an electrical lock; that's why you have to press brake to shift from Park to Reverse or Drive, so the functionality will be the same. Since the stock shift tube is still being used, the functionality of the shifter remains the same, other than the mechanical locking mechansim. Going to test in next couple of days. I think it'll look sick! I am looking to mod the console piece to eliminate the indicators on the console and replace with the indicators on the shifter. Since my car is carbon fibred, I can build an insert that reduces the opening to the correct size for the new shift knob boot, re-carbon fibre the whole part and then you'd only see the P R N D lights on the shift knob and cluster.
