If you can’t afford a BMW M4 the next best thing is an Alpina 3 Series. If you can’t afford that either, then you have to buy a 435i and have it tuned. This brilliant BMW 435i kitted-out by KBS Motorsport is a good example of what you can achieve proper parts.  

KBS Motorsport BMW 435i shown here features a carbon fiber body kit by Japanese tuner 3D Design, consisting of front spoiler, side skirts, rear diffuser with quad outlet, trunk spoiler and roof spoiler. The kit fits on the 4er’s stock bumpers and sills and give it a lower, sportier stance.

To fill those quad outlet openings in the new carbon diffuser at the back, KBS Motorsport BMW 435i is fitted with a professional Eisenmann exhaust system featuring 4 x 76mm adjustable tips. They do a good job of mimicking the M4’s rear end.

This 4 series is still a work in progress and BS has plans to install BMW Performance Brakes on it as well a set of ADV7 M.V2 20-inch wheels.
