Most Popular BMW F30 & F31 Exterior Upgrades

When upgrading the exterior of a BMW F30 or F31, most owners focus on a combination of aerodynamic styling and visual balance. The most common upgrades include:

Front Splitters

A front splitter instantly sharpens the front-end appearance, giving the car a lower and wider hint. It’s often the first modification owners choose due to its high visual impact.

Rear Diffusers

Rear diffusers add aggression to the rear of the car and help balance the look once a front splitter is installed. F30 and F31 diffusers differ slightly in design due to body shape.

Side Skirts & Extensions

Side skirts visually connect the front and rear upgrades, lowering the profile of the vehicle and creating a cohesive look.

Boot Spoilers

A subtle boot spoiler adds a performance-inspired touch without overpowering the factory design, especially popular on F30 saloons.

Full Body Kits

A full BMW F30 or F31 body kit combines all key exterior parts into one complete styling solution, ensuring consistency across the entire vehicle.

BMW F30 vs F31: Key Differences for Body Kits

Although the BMW F30 (saloon) and F31 (touring) share the same platform, there are important differences when it comes to exterior styling parts:

• Rear Design: The F31 touring has a different rear bumper shape, meaning diffusers and spoilers are not interchangeable.

• Visual Balance: The longer roofline of the F31 benefits more from extended side skirts and rear-focused styling.

• Spoiler Options: F30 boot spoilers differ from F31 roof or tailgate spoilers.

Always check compatibility before purchasing, as parts designed for the F30 may not fit the F31 correctly.

Full Body Kit vs Individual Parts – Which Is Right for You?

Choosing between a full body kit and individual styling parts depends on your goals and budget.

Full Body Kit

Best for:

• A complete exterior transformation

• Matching finish and design across all components

• Owners who want a cohesive, performance-inspired look

Individual Parts

Best for:

• Gradual upgrades over time

• Budget-conscious builds

Many customers start with a front splitter and diffuser, then build up to a full package.
