Elevate the driver-focused cockpit of your F40 M135i xDrive. While the UKL2 interior features modern digital displays and M Sport styling, drivers taking their car to the track or seeking ultimate lateral support can upgrade their cabin with highly supportive Interior Parts (Racing Seats) designed to shed weight and lower the seating position. To enhance tactile shifting control when operating the 8-speed Aisin automatic transmission, install our extended Uprated Shifter Paddles for instant gear selection at your fingertips.
