It would take a brave man to start meddling with Merc’s lovely CLK63 Black Series but clearly Danish tuner Kleeman thinks it can be improved. The 6.2-litre V8 has been treated to a remapped ECU and an upgraded exhaust has been fitted which includes high-flow exhaust manifolds and downpipes with sport catalytic converters.
All this means that power has been increased from 507bhp to 545bhp. The gorgeous original 19” AMG alloys have also been binned in favour of Kleeman TS-6 3-piece 20” rims and a Kleeman badge now sits on the boot.
