Here's Your Chance To Buy A Manual-Converted BMW M3 CSL

This well used but extremely well-cared-for M3 CSL has the one thing we all wish the original had - a manual
Here's Your Chance To Buy A Manual-Converted BMW M3 CSL

The BMW E46 M3 CSL is, many would argue, a manual gearbox away from M car perfection. Although cutting edge at the time, the SMG II transmission the CSL left the factory with is noticeably slower and less consistent than a modern dual-clutch automatic, and not as engaging as stick shift.

For all its focus, it seems a shame BMW never at least offered a manual option. One owner seems to have agreed and taken matters into his own hands.

The most recent keeper of the example enlisted Darragh Doyle of Everything M3s to give it the manual shift action we all think the CSL deserves. Handily, this didn’t involve transplanting a whole new gearbox.

The SMG transmission is as a ‘robotised manual’ rather than a true automatic, meaning it’s possible to ditch the hydraulic pump, the hydraulic clutch actuator and all the electric gubbins that make the shift happen, then replace with the parts necessary for a manual cog change. To sweeten the conversion even further, Doyle also changed the final drive ratio from 3.62:1 to 4.1:1.

The limited-slip differential has also been rebuilt with a revised ratio, but other than that, nothing has been fiddled with. But why would you need to? BMW really went to town on the CSL. Power increased over the standard M3 thanks to a rebuilt top end for the S54 inline-six and a carbon fibre intake manifold, while the weight dramatically dropped by 110kg.

This was thanks to a variety of measures including the ditching of most luxuries (some of which could be optioned back in for free) and much of the soundproofing, plus the use of carbon-fibre-reinforced plastic panels and even thinner glass. Revised springs and dampers sharpened up the body control, with grip and traction increased further via the fitting of Michelin Pilot Sport Cup semi-slick tyres.

If like us, you now want this thing with every fibre of your being, we’ve good news - it’s up for sale via an online auction from Collecting Cars. With over 140,000 miles on the clock it’s been heroically well used but also very well looked after, and there’s a decent amount of tread left on its tyres, which are the newer Pilot Sport Cup 2s.

At the time of writing the auction is at £25,000 with seven days remaining. Since the cheapest CSLs in the classifieds right now are hovering around £50k, that figure is set to rise considerably. For what might just be the greatest M car BMW never made, though, the high price of entry will surely be worth every penny.

Fun fact: the sequential transmission on the E46 M3 was so terrible that BMW changed transmission suppliers with the E90 and all subsequent BMW models. Previously they had ZF transmissions, but E90 and newer are all Getrag. Some say that might have something to do with the E92 M3 having a dual clutch transmission, but ZF also offered one at that time.

Is that for M-models only or in general? Because I am sure BMW has been using a blend of ZFs and Getrags since the E39.

You are aware that the E46 M3 SMG Gearbox is a modified Getrag 420G gearbox?
At the time the ZF S5D 320Z offered on the lower spec cars, was arguably stronger than the Getrag 250 boxes

Before everyone starts hating on the SMG gearbox, I own an E46 M3 with an SMG ‘box and, having done my research and trying both cars, I opted for the SMG. The main reason the SMG was chosen for the CSL models was mainly because it’s brutal and kicks you in the stomach when you’re hammering it down a B road or a track, despite being a tad clunky and dim-witted in Central London traffic. At the end of the day, you either love it or you hate it I suppose :)
