Hieu, Ron told me that the Gen2 has a relatively major upgrade to the the offset selector rod. This upgrade includes a larger more rigid pivot and ergonomic changes. The current shifter follows BMW performance ZHP shifter's ergonomics which Ron said he disliked for a long time. As a result, he built a new shifter, the Gen2, with updated ergonomics and larger pivot boot in May and supplied a few to selected shops and users. Based on feedback he got from these shops and users he's ready to provide the Gen2 and I was offered the choice so I went with the Gen2 for my ZHP.
I looked into the UUC EVO3 SSK however there was no correspondence from them and Ron's communication has been excellent and comments from those of you who went with the AutoSolutions kit was more than enough for me to pull the trigger to get Ron's product. Today's phone conversation with Ron sealed it for me and I'm glad I will be getting the Gen2 for my ZHP
