The main modifications to the XJ are the lowered ride height, the new 21-inch wheels and a redesigned interior. The car gets a new front end design that bolt on to the standard car, and includes larger air ducts, and LED daytime running lights.

Other styling enhancements are the redesigned front fenders and rocker panels which lead back to the car's rear, where a new apron, tailpipes, and diffuser can be found. A boot spoiler completes the sporty look.

Startech has also worked with the suspension and lowered the car by 30 millimetres, to go along with the new 21-inch forged mirror polished wheels. For the interior, leather and Alcantara upholstery matches with the wood trim, which can be specified in either brown mahogany or blond ash wood, in a gloss or matte finish.
