The German tuner is providing two performance packages for the coupe and convertible, the first of which boosts power to 582bhp and 533lb ft, and the second of which boosts power to 602bhp and 533lb ft.
There's no indication on how this will affect performance, but we expect a little improvement over the RWD coupe's 3.9-second 0-62mph time and 180-mph peak speed.
Phew.
New springs, which lower the M4 Comp by up to 20mm, or 'RS' coilovers, which lower it by 40mm, are two suspension upgrade choices.
New 20-inch lightweight AC3 or AC1 alloy wheels in silver/anthracite or glossy black are also available.
Naturally, there are a slew of additional body pieces that purport to boost downforce – at least at speeds of 140mph – including a 40-kilogram front splitter and a 50-kilogram rear wing that's special to the Coupe.
A retrimmed steering wheel in nappa leather and black Alcantara with a centre marker is available as an option, but otherwise, there's plenty of aluminium in the form of shifter paddles, pedals, a footrest, the key holder, and more.
At the very least, it's a shift from carbon.
