If you’re in the mood for a stop-you-in-your-tracks combination of car and wheels and tasteful modifications, then allow us to introduce you to Claudio Fusco’s Mystic blue 2004 tuned BMW E46 M3. Spotted at a cars and coffee event tucked between a few other cars, we knew we had to shoot it.
As the years go by, we begin to cross into the realm of E46s becoming sought-after classics. It feels like people are starting to appreciate them even more as a well-designed and well-built machine. Especially in M form.
Some people label everything a classic, but but there is absolutely no discounting the E46 M3’s stake to the title. Several years ago, clean examples could be found for under £10k. Now you’d be lucky to find a clean one for twice that figure, and that number is rising every day.
People looking for a sports car with an analogue feel that still retains some creature comforts such as air con and cruise control may look no further than the M3. Its pace and handling are hard to beat at the price point.
With 343hp delivered at a heady 7900rpm courtesy of that 3.2-litre straight-six, the E46 M3 is an intoxicating machine. It delivers a thrilling driving experience whether equipped with the six-speed manual gearbox or the SMG. Some people love the latter, some people don’t. Claudio converted the SMG equipped E46 to a manual to unleash the full potential of the chassis.
The swap is pretty common nowadays and relatively easy to do, the only downside being the ever-increasing cost of parts. The SMG gearbox is still used. The pump and solenoids, along with the pedals etc. can all be swapped out. This makes it a lot simpler than a regular automatic to manual swap.
Having bought it several years ago from County Limerick, Claudio got to work putting his own touches to it. Not wanting to take all the credit for the build, Claudio is quick to point out that the previous owner did a great job in maintaining and tastefully modifying the car. “The E46 M3 was always my dream car,” Claudio enthuses.
“After owning three E46s in my past and being a member of numerous BMW forums, I had always followed threads on fellow members’ cars. I remember out of nowhere a specific E46 M3 I had been following came up for sale. After some quick thinking, I sent a message to the owner. Within a day or so, he replied saying he was thinking of selling it on as he fancied a change.
“I knew it was tastefully modified and had been kept in fantastic condition mechanically and cosmetically, so I bought without viewing. The essential maintenance all M3s need, such as rod bearings, the rear subframe reinforcement kit, new driveshafts etc. had all been carried out,” he says.
As well as the gearbox conversion, the previous owner also added some tasty mods, like the carbon intake, the KWs, BBK and CSL boot lid. However, it wasn’t long before Claudio got the itch to take things a bit further.
On the day we met up with him and his immaculate tuned BMW E46 M3, we took a rare opportunity to get a ride along. This car is absolutely spotless inside. It’s a real credit to him. Beautiful Cinnamon leather adorns the retrimmed M3 seats. Then there’s a CarbonTastic flat-bottom carbon fibre steering wheel, retrimmed in fresh black leather.
The inside feels like new, and you’d never think it was coming up on being 20 years old now. The Avin Avant 4 head unit with Bavsound speaker upgrade injects some modernity to the interior. It also brings helpful additions like Spotify to the elderly E46 tech. The dash and door trims have also been dipped in carbon fibre. They really modernise the look of the cabin. Other little additions like the weighted F10 M5 gear knob along with the pedal trims really help elevate the experience of being sat inside this fantastic machine.
Outside, the tuned BMW E46 M3 looks OEM. However, it has loads of small details that make all the difference to the eagle-eyed enthusiast. The wheels are the first obvious addition and the one detail that really made it stand out to us initially. The polished dishes and gold recessed hardware topped off with the absolutely insane concave faces on those huge 9.5×19” and 11×19” BBS RSIIs just draw your eye to them the second you see the car.
The wheels shipped to Ireland from the UK after Claudio contacted a fellow E46 owner about parting with them. In his eyes, they’re the perfect E46 wheel, and we’d have to agree. Finished off in metallic silver, the centres sparkle in the midsummer sun.
The carbon rear diffuser juts out above the Eisenmann sport exhaust with the larger 83mm Le Mans tips. And then there’s the CSL-style boot lid with the integrated spoiler. It’s hard to spot at first, but once you do, it really adds to the aggressive look of the car.
Visual modifications aside, this car really gets exciting when it comes to the performance side of things. Huge BMW Performance calipers and CSL discs tucked behind the BBS wheels, painted in a gold reminiscent of the Phoenix yellow E46 M3 colour.
Claudio points out that while the brakes are a great upgrade over the standard car’s lacklustre effort, he plans to swap them out for a Brembo GT kit.
Pop the bonnet, and you’re greeted with that sublime S54. It features an Evolve Automotive carbon airbox strapped to the throttle bodies. The carbon airbox combined with a remap unleashes a few extra horsepower. But it also unlocked the sound of the straight-six at full chat, giving it an intoxicating CSL-esque induction noise. Meanwhile, a Supersprint resonated centre section and an Eisenmann back box combine to serve up an awesome note.
KW V2 coilovers take care of the handling. The car rides almost as comfortably as stock. Apart from the reduced body roll and the ability to fine-tune the ride to the desired height and stiffness. Millway pillow ball adjustable top mounts add another level of adjustability to the already impressive handling setup.
On our ride along, it was evident just how well the tuned BMW E46 M3 had been set up, the cornering was sharp and direct, yet the ride wasn’t stiff or bouncy, a valiant effort on roads as bad as the ones we have in Ireland.
Claudio rarely finds time to spend on cars due to work, but when he does find a small window to himself, he takes the M3 out any chance he gets. His build is proof that the E46 can be subtly improved to emphasise the most special aspects of what makes this chassis one of the true greats. The late ’90s and early ’00s gave birth to some of the most iconic cars of our time.
Looking at the example before us and having had the pleasure to ride along in it, we can absolutely see why owners like Claudio say there aren’t many cars left that even come close to the experience of owning and driving a tuned BMW E46 M3.
