    Adding a rear spoiler without the front splitter - is this a problem?

    Hello,

    Just got my new 2019 440i Xdrive! I got my car with the "BMW M PERFORMANCE CARBON FIBER REAR SPOILER" installed at port. Yesterday I read that BMW saying "TO ENSURE PROPER DRIVING BEHAVIOR/AERODYNAMIC BALANCE, IT IS STRONGLY RECOMMENDED THAT THE REAR TRUNK LID SPOILER BE INSTALLED IN CONJUNCTION WITH THE FRONT SPLITTER". I do have the M package but it seems like the front splitters I need are not included in the package.

    Is this a marketing thing, or do I really need now to get front Splitters? Hope I can get some advice and hopefully I do not need to put more $$$ in the car.

    Thanks Ron

    Unless you plan to track it or drive at 150mph, it is not a problem.
