Elevate your Gran Coupe with premium rocker extensions from 3DDesign. Handcrafted from pre-preg 2x2 twill carbon fibre, these low-line sill extensions deliver an unmistakable motorsport look, sharpen the side profile, and complement factory body lines for a true OEM plus finish. Expect clean weave alignment, lightweight construction, and a purposeful stance that enhances visual width and helps guide airflow along the flanks.
Perfect for enthusiasts chasing a high-end aesthetic upgrade, these side blades integrate seamlessly with factory bumpers and doors, adding presence without looking overdone. We have fitted these in-house for customers and on our own builds. Fitment has been excellent and feedback on the finish and durability has been consistently positive.
