Constructed For SEMA, Debuted At Elmia: Magass Design’s Infiniti G37 Coupe
5 min read
Most US-based {custom} automotive builders have, at one level or one other, imagined showcasing their onerous work on the annual SEMA Present. For builders exterior of america, it’s the form of dream that just a few will realise.
Christian Magass of Magass Design in Gothenburg, Sweden has a purpose: SEMA 2023. And that is the 2010 Infiniti G37 Coupe (aka G60) he hopes can take him there.

Christian is a design engineer who’s spent nearly all of his grownup life constructing automobiles. For a very long time they had been solely European makes, however in 2021 he lastly determined to dip his toes into the Japanese pool. I’m very glad he did.

Let’s begin with the apparent improve: the entrance finish. What the unique G37 lacked in appears to be like, Christian’s automotive makes up for with a 2022 Infiniti Q60 facelift. How significantly better does this look?!

Nevertheless it’s simply the beginning. Customized metal work has widened the Infiniti coupe by 90mm within the entrance and 120mm on the rear, with the additional width blended into the bumpers for a seamless look. Talking of bumpers, the G37-spec rear now advantages from a superbly built-in Mercedes-AMG C 63 diffuser.
The diffuser just isn’t the one cross-manufacturer improve although. See the cumbersome G37 door handles? No you don’t, as a result of Christian has changed them with flush-fitting Tesla Mannequin 3 equivalents.

Just like the roof, the trunk lid has been customised with carbon fibre laid over metal, however earlier than that occurred a modified duck tail spoiler was added on the rear.
Though Christian is aware of his method round bodywork modification, his speciality is {custom} paint, and the Infiniti’s exterior end is testomony to his expertise with the gun. The principle color is BMW Isle Of Man Inexperienced (with a bit additional Magass Design aptitude), however you’ll additionally discover Volkswagen Black (with a refined inexperienced pearl) and Renault ENV Yellow within the combine. Christian didn’t skimp on the gloss, making use of a minimal of 5 and as much as 9 coats of Standox VOC Xtra Clear relying on the realm.

Yep, it’s painted beneath too. I actually want the automotive might have been displayed suspended within the air, so everybody might correctly see the great work Christian has finished right here. SPL entrance higher management arms, SPL rear camber hyperlinks and rear mid hyperlinks have discovered their method onto the G37, however the low experience peak and ultra-low stance when parked comes courtesy of an Air Lift Performance 3P/3H air suspension system.


The mixture of air experience and people custom-widened fenders (with carbon fibre interior liners) permits the Infiniti to swallow up a big wheel and tyre mixture. Wrapped up in Nexen N’Fera rubber, the 19-inch Weds Kranze Vishunu 3-piece wheels – with inexperienced anodized bolts from Pood Kustoms – haven’t escaped Christian’s {custom} contact both. The wheels’ interior barrels function a singular hexagon design, with actual depth achieved via a minimum of eight coats of paint and clear.
Within the brake division, {custom} green-painted Akebono callipers are paired with slotted and drilled GKTech rotors.

You’d have caught a glimpse of the GTHaus Meisterschaft cat-back exhaust system a second in the past, and that leads us underneath the bonnet to a really uncommon trying VQ37VHR within the wire-tucked bay.

The Nissan 3.7L V6 got here factory-fitted within the G37; what’s not manufacturing facility is the R35 GT-R consumption manifold that Christian tailored to suit it. This was, understandably, fairly a problem, however one thing achieved via 3D-scanning and, subsequently, a custom-milled spacer. The engine itself has been rebuilt with CP solid pistons and Carrillo rods, whereas the gasoline system was upgraded with a Walbro Motorsport GST520 pump and Deatschwerks injectors. Retaining pure aspiration, Christian hopes to see greater than 400hp on an E85 tune.

Exterior. Tick. Undercarriage. Tick. Engine bay. Tick. The inside? You already know that Christian has finished one thing particular in right here too. For probably the most half, the cabin retains its unique gear, however every thing has been customised to carry an entire new really feel to the area.

From the dashboard to the door playing cards and seats – the latter that includes a mixture of beige Alcantara and matching leather-based, trimmed by Thors Sadelmakeri – the G37’s inside has been elevated to a brand new stage.
Out again, you’ll discover a green-painted SRS Studio half roll cage. The metal bars have rendered the custom-trimmed again seat unusable for passengers, but it surely’s the right spot for the air suspension tank, which has additionally been upholstered.

Proudly displayed on the rear deck in a {custom} enclosure is the Air Elevate Efficiency manifold and a glimpse of the system’s polished hard-lines.

The modernization began with the Q60 entrance finish and continues into the cabin with a big Tesla-style show, which amongst different issues controls the spectacular audio system.


The G37’s boot has been decked out with the newest Stroker sequence audio gear from Cerwin Vega, equipped by dBAkuten. There are 21 items to the setup, together with eight 6-inch mid-bass audio system, six 4-inch tweeters, two 12-inch subwoofers, two 4-channel amplifiers and two monoblocks, all operating via a Nakamichi sound processor.
Practicality is all the time a difficulty when you’ve put in a sound system of this magnitude, however as Christian has plans to get the Infiniti on monitor sooner or later, he designed the complete boot setup with simple elimination in thoughts. With magnets securing the system, it takes simply quarter-hour to take away.

Christian’s onerous work has already been rewarded in Europe with a number of awards coming his method on the 2023 Elmia Customized Motor Present, and in addition the second place outright trophy at Tuning World Bodensee in Germany again in Might. Crazily, he’s not completed but, with extra enhancements deliberate for his Infiniti G37 over the approaching months.
Will the SEMA Present occur for him? We actually hope Christian can obtain his purpose of getting the automotive to Las Vegas. Within the meantime, you may try his YouTube channel, which covers off just about all features of the construct because it got here collectively.
