Funny I have the same color M235ix and have the same Dinan kit on my car. I must say it is a massive difference. Completely changes the car in terms of performance. In shitty conditions I got a 0-60 time of 4.0 seconds and the car feels like it has gotten faster as the tune self adjusted. The only thing that dinan doesn't tell you is the turbo install is a ton harder on the xdrive cars. Took two days to install and was a nightmare. Was worth it in the end.
P.S. does anyone have suggestions on the Dinan badge, I still havent put mine on I was going to replace the trunk xDrive badge but the finish doesnt match. Any Suggestions.
