The current generation of the CLK has always struck us as innocuous and forgettable, but the CLK63 AMG Black Series is a different machine. It’s got revised front and rear aprons with carbon air intakes and diffuser fins, redesigned side skirts, and a carbon fiber rear spoiler. Those are the subtle changes. There’s no mistaking the flared carbon fiber vented fenders, and the staggered-width wheels are also striking. These AMG forged rims measure 9 x 19 in front and 9.5 x 19 in back, and wear Pirelli P Zero Corsa tires sized 265/30R19 in front and 285/30R19 in back.
