Thanks mattmarchy!
Unfortunately the Maxton Design racing splitter I not available for the M140i
So I end up looking for other options ... that are not many tbh
So I decided to look in the back of the car and order the rear diffuser from Maxton ... This fully available for my car.
Ordered and deliver time is 5-6 weeks .... long wait
CENTRAL REAR SPLITTER BMW 1 F20/F21 M-POWER (WITH VERTICAL BARS)
I've chosen the carbon looking + red stripe
Will post some photos from the before + after
