SWORKz have introduced a new carbon fibre wing spacer for the S14-3. Machined from high-quality carbon fibre, the spacer links the wing support posts to add more rigidity and strength and it makes the wing flat which results in greater stability. Using two spacers create more downforce and stability at high speeds without reducing the corner speed. The wing spacer comes in set of two including two mounting screws.
