I can pretty much guarantee it would be a significant install/modding required. It isn't going to be plug and play, so wouldn't shock me if it costs a few grand... my guess is if you were ok spending a few grand extra you probably would have done it by getting the gt2 in the first place. That was from my experience with other cars, i read a few people tried modding their shifters and it was a pretty expensive install. I like the shifter but I don't like it that muchI have the GT model... and would really like to upgrade the T-Shifter.. I am not looking to add the "shift by wire tech".. just like the look of the GT2 knob... any thoughts?
