German tuners Arden have given a preview on what their package for the Jaguar XJ has in store. As they released renderings show, the Arden XJ 351 is likely to get a new front spoiler and more angled side sills. But the tuning program cannot of course end with just the front spoiler; you can expect Arden to increase the car’s performance with a retuned engine, powertrain, and a new exhaust. Other changes may include a new suspension, brakes, rear spoiler and 21-inch tires to the package. Also included may be certain cosmetic changes like a new gear lever, aluminum pedals, and floor mats.
