Fit a 2016 RWD 6MT 228i with zero issues. Aligned to factory spec. Drop is exactly 20mm. Ride is perfect. Nice and flat. Not jouncy at all.

I have had a 2014 228i 6MT RWD with the 704 M-Sport, this 2016 228i 6MT RWD with base suspension, and now the same 2016 with the M Performance Suspension (p/n's above).

This is the best of the three. Well worth the hassle. It is a shame that BMW NA removed the official compatibility for the US.

Thanks so much for this!
