Triple R Composites Tesla Model 3 Side Skirt Extensions
Give your Tesla Model 3 a sharper, lower look with these Triple R Composites side skirt extensions. They run along the factory sills to continue the clean lines of the car and match the style of front splitter upgrades.
The design adds subtle splitter upstands and side fins that make the car look wider and more planted on the road. The effect is a sportier stance without being over the top.
- Clean, OEM+ style that follows the Model 3 body lines
- Makes the car look lower and more aggressive from the side
- GRP main skirts for strength, low weight and a quality finish
- 3D printed Nylon 12 side fins for precise fit and detail
- Gloss black finish to match most styling packages
- Supplied with a full fixing kit for installation
Construction and finish
The main skirt extensions are made from GRP (glass reinforced plastic). This is a lightweight plastic strengthened with fine glass fibres, which helps it stay rigid and resist cracking.
They are finished in a gloss black gel coat, so the colour is built into the part, giving a smooth, shiny surface that matches other gloss black trim.
The side fin pieces are made from Nylon 12 using SLS 3D printing. This process builds the fins layer by layer for accurate shapes and crisp edges. The fins are then painted in gloss black to match the skirts.
Fitment and compatibility
These Triple R Composites side skirt extensions fit Tesla Model 3 models from 2017 to 2023.
Check any existing side skirt or aero kit on your car before fitting, as some aftermarket parts may cause clearance or mounting issues.
