Hello all, this is my first time posting. I am the first person to successfully retrofit paddle-shifting on existing E46ers with Steptronic system.
Kit may or may not include the SMG wheel depending on you. I will provide everything else to retrofit. This includes a customized wiring harness. So far, I have performed this retrofit on 4 cars including mine.

All are working perfectly well!
If you're interested in this kit and you're from So Calif, drop me an email. And we will go from there.
