Triple R Composites BMW M135i/M140i F20 5 Door Side Skirt Splitters
Give your M135i/M140i F20 a sharper, lower and more purposeful look with these Triple R Composites side skirt splitters.
Designed to sit beneath the factory side skirts, they create the effect of a lower stance and a wider road presence. This helps your 1 Series look more like a track-focused car without major bodywork changes.
- Sporty, aggressive styling that complements the F20 body lines
- Gloss black gel coat for a clean, high gloss finish
- Subtle side profile change that makes the car look lower to the ground
- Supplied with full stainless steel fixing kit for a secure fit
Why choose this kit
The gloss black surface matches other common exterior upgrades like front splitters, rear diffusers and gloss trims. It is ready to fit out of the box, so there is no need for painting.
The splitters help smooth airflow along the sides of the car at speed. This can give a more planted feel on the road, especially when combined with other aerodynamic parts, although the main benefit is visual.
Fitment and compatibility
These side skirt splitters are designed to fit BMW 1M135i/M140i F20 door models from 2011 to 2019.
Check your car is a 5 door F20 before ordering to ensure correct fitment.
Use the vehicle lookup on our site or check the Vehicle Fitment tab for full details before ordering.
Supplied as pictured in a gloss black gel coat finish with a full stainless steel fixing kit included for installation.
