A three-part bumper attachment, massive wheel arch flares front and rear, side skirts in carbon look and a rear apron with two molded diffusers make the compact station wagon into a power athlete. The widebody kit is available in the style of the Cup Racer. JE DESIGN offers a rear diffuser that fits both the original exhaust and the JE DESIGN flap exhaust system. Sporty and ambitious drivers who want to hunt their Cupra ST down the race track grab the LED rain lights corresponding to the FIA regulations. This can be easily integrated into the rear diffuser.

Such a racy optic needs the right sound! The tuning specialists JE DESIGN know this. They offer a stainless steel flap exhaust system with EC approval for the Leon Cupra ST. This is controlled by the original driving profile selection made by Seat. The driving profiles Normal, Sport and Cupra can be selected. In the profiles Normal and Sport, the exhaust flap is closed and the exhaust sounds sporty but discreet. Cupra mode is different: With the flap open, the exhaust system reveals its full sound – music to the ears of Seat fans. There is a sound upgrade made of four striking tailpipes with a diameter of 80 millimeters each, or one tailpipe oval on each side in dimension 160 x 90 millimeters. The downpipe jointly developed by JE DESIGN and HJS for the flap exhaust system with 76 mm diameter is available. This accessory also has an EC approval.

JE DESIGN emphasizes the sporty appearance with a performance upgrade for the Cupra ST. An additional electronic box allows the power of 206 kW/280 hp to be increased to 258 kW/350 hp with a maximum torque of 440 Nm. It doesn't top off until a speed of 280. The performance enhancement includes a two-year warranty on engine, driveline and transmission (from the first registration).

The spring set , available for the original shock absorbers, provides 20 millimeters lowering. Alternatively, JE DESIGN offers the KW coilover suspension DDC Plug & Play. The application brings the fiery Spaniard as much as 45 millimeters closer to the tarmac.

Complete wheel sets with light alloy wheels from ATS or OZ up to a size of 10 x 19 inches and 265/30 R19 tires complete the offer.

Complete conversions are possible directly from JE DESIGN – acceptance by an official inspection organization included.
