Eyecatcher: The smart fortwo

Even when stationary, Lorinser’s refined smart will impress and comes with an extra dose of pep. The reason for this is the newly designed bodywork components: Front spoiler add-on part, side skirts and rear bumper add-on part were re-designed and made considerably more dynamic by Sportservice Lorinser designers while taking the typical smart styling into consideration. A special highlight is the rear bumper add-on part. This makes room for the now centrally positioned stainless steel tailpipes of the Lorinser sports exhaust system which produces sounds normally confined to the racetrack.

Lorinser typical perfection in every detail. The areodynamic-set from Lorinser satisfy all expectation when it comes to design, safety and quality.

Carlsson Program for the smart fortwo 453

How much luxury can you pack into 2.70 meters? Carlsson provides the answer with their new smart fortwo (453). Labelled Carlsson CK10, the distinctive aerodynamic components and alloy wheels of this tiny wonder make it stand out from the crowd. The 17-inch Carlsson 1/16 DS alloy wheels fill out the wheel arches, while Carlsson sport springs lower the ride height, giving the car a more purposeful stance.

The Carlsson front spoiler and rear roof spoiler deliver a sleeker look and aid stability at speed. A matching rear valance, with cut-outs for the four-tailpipe sports exhaust, completes the sporty look. The bespoke interior, upholstered in the finest leather trim, is befitting of a small luxury car. Carlsson customers can specify a wide variety of colours and finishes to make their car truly individual.

We carry the Carlsson Product Line in stock. We are experienced in how to properly install every Carlsson Product and can assist in building you a fully custom Carlsson smart with a very large variety of options.
