Doyle argues that the manual CSL is what BMW should have built in the first place, and he’s far from the only one. His conversion pack is sold as a complete fitted kit, with the manual components replacing the electrohydraulic element of the gearbox with a traditional clutch pedal and gear stick arrangement using 180 genuine BMW parts. The process only takes a few days with the gearbox removed, a self-centering shifting mechanism added, a new clutch and flywheel fitted and the engine management recoded for a manual transmission.
What’s more, keeping in mind that the E46 is a rare and collectible car, the entire process is reversible with all factory SMG parts retained to ensure the possibility of a complete return to stock form at any time in the future.
As you can see in the video below, Ferrari and vintage racing specialists DK Engineering is already endorsing Everything M3s’ conversion job, which starts at £3,500 or roughly $4,600 USD. In their press release, Mr. Doyle added that “while there is a waiting list for the conversion, lead times are reasonable.”
