Will this retrofit damage the transmission, cause the car to stop suddenly, or behaves irregularly like shifitng suddenly from M5 to M1?
The only damage we have heard of is the smile on your face. We have sold more than 200 kits already to BMW owners from Singapore, Malaysia, to Canada, US, Brasil, Eastern Europe and more countries.None of us have reported anything unusual. The retrofit is tested at AutoX events and track schools. Everything works well.
