The customization program for the Leon consists of various aerodynamic components. The front spoiler or the front spoiler corners (only FR & Cupra), the side skirts and the rear apron attachment in carbon look or the rear apron corners with a central diffuser insert for the FR & Cupra variant make the compact Spaniard appear much sportier. The sporty look is rounded off by matching lowering springs that screw the Leon approx. 35mm closer to the asphalt.

There are two versions of the matching sound for the look at JE DESIGN. Either the exhaust system ends with a stainless steel double oval tailpipe in the middle of the rear (not for FR & Cupra). Or two twin tailpipes with 90 mm diameter of the four-pipe system produce the beefy soundscape on the left and right. JE DESIGN has the right rear apron attachment for both variants.
