As a result, the power to weight ratio drops from 4.4kg per HP in the stock model to 3.8 kg per hp in the KS-1 S.
Visually, the KS1-S differs from the standard 1 M Coupe thanks to new aerodynamic parts designed to minimize drag and increase downforce at high speeds, as well as the quad 83 mm exhaust pipes.
Kellener’s 1 M Coupe now rides on new 20-inch alloy wheels shod in tires size 245/30 at the front and 265/30 at the rear.
The company also worked on the suspension settings and added an adjustable coil-over system, which gives the driver the opportunity to adjust both rebound and compression independently.
Changes were also made also in the interior with two-tone black and white perforated leather and alcantara covering the dashboard, door panels and front and rear seats.
