F30 M Sport Rear Bumper Conversion

In the BMW world, “M Sport” is a package sought out by enthusiasts that adds aggressive bumpers and side skirts, larger brakes, and driver focused suspension. Because F30’s with the M Sport package are so desirable, they tend to be harder to find and always demand a higher price. Luckily, for those of use who have bought a non-M Sport F30, changing the bumpers isn’t as difficult as you might think. In this guide, I’ll show you how to convert your F30 BMW’s rear bumper to an M Sport bumper. 

The M Sport bumpers from Kies Motorsports come unpainted. The paint shop will ask for your VIN number so they can order the exact paint color for your car. You’ll also give them your fuel door so they can be sure the color is a perfect match. Expect to pay around $400 to have the rear bumper professionally prepped and painted. I had the front bumper, rear bumper and side skirts painted all at once for $1,000. A quality professional paint job is not cheap, but this is not an area to cut corners (speaking from experience).

Tools required: Torx bit sockets, 8mm socket, electric ratchet
Install time: 2 hours

Step 1
Remove the T20 and 8mm screws in the wheel well.

Step 2
Remove the 8mm screws from the underside of the bumper

Step 3
Remove the plastic drip covers from the tail lights and remove the 10mm nuts.

Step 4
Pull straight back on the tail light and unplug the harness.

Step 5
Remove the 10mm screws from the top of the bumper.

Step 6
Put a piece of masking tape on the body of the car to protect the paint before removing the old bumper.

Step 7
Carefully remove the rear bumper. If you car has parking sensors like mine, each sensor has it’s own wiring harness. You’ll need to unplug each one while removing the bumper.

Step 8
Plug the parking sensor harnesses into the new M Sport bumper and install it on the car.

Step 9
Reinstall the tail lights and bumper hardware to secure it in place.
