Pushing out 700hp, slathered in carbon and finished in a stunning shade of Individual purple, this modified BMW M4 G82 is machine enough to convert even the most ardent of haters into a fan.
Are we all agreed that the G8x M3 and M4 look okay now? Is that something that everyone is on board with? We’re sure there are plenty of people out there who felt that way from the off, but likewise, we reckon there are also plenty of people out there – quite possibly more – who didn’t share that enthusiasm for the latest generation of M3 and M4. We would count ourselves among those, and we’re not going to pretend we were on board with the styling.
But, as is almost always the case, time (around three years at this point) has done wonders, and not only have we now got used to the styling, it’s honestly grown on us. We still maintain that it is very color sensitive and that some aero additions that emphasize the angular design work wonders for the car. So it’s a good job that Viktor Örtegren (@viktoroertegren) chose purple for his G82 M4 and then proceeded to throw a whole load of carbon at it because the end result is a ferocious-looking car that will surely convert even the most die-hard of haters.
Viktor’s Car History
Hailing from Sweden, Viktor has been passionate about BMWs since he was little. “Since childhood, there has been only one car manufacturer for me,” he grins. “I can still remember going to Germany with my father when I was young and seeing an E36 M3 for the first time. So the E36 is extra special to me,” he adds, and it’s no surprise what he chose as his first car. “I got an E36 325i Coupé just before my 18th birthday. This was my favorite model, and these were pretty cheap to get in Germany at that time. Of course, it had super-wide ‘German-style’ wheels and coilovers so low that it was almost impossible to drive,” he laughs, but it was the perfect introduction to BMW ownership for the young Viktor and cemented his love for the brand.
Nowadays, Viktor is the CEO of Schmiedmann’s Swedish branch, which puts him in the enviable position of being surrounded by a near-limitless selection of BMW upgrades from countless brands, so, unsurprisingly, he’s always got a couple of modded cars on the go. “We had an F82 M4 that had a feature in Performance BMW a few years ago (April 2019). After that, I’ve been mostly doing some endurance racing with an old E46 that I share with some friends. This is an E46 328i with a WTCC body kit, upgraded brakes and some smaller modifications to the engine. The rules in the racing series prevent us from doing too much with the engine, so our main focus on that one has been to get the weight as light as possible and traction as good as possible,” he explains.
Latest builds
“Then there is the G82 M4, of course, and we just got an E36 325 that we will rebuild as an endurance race car for next season. I usually borrow one of the F20 118is that we have at work for my commute,” he smiles, so it’s fair to say he’s living his best BMW life right now.
“We are always trying to be early with new models as show cars,” says Viktor as we turn our attention to the G82. “We really thought the new M4 had potential, and, personally, I was missing having a track day car that can be used for both street and track,” he adds with a smile. “This one was ordered new from the factory, and we ordered parts the same day as we ordered the car! When we decide to do a big project like this, we always try to stand out and be one of the first with the mods. So some of the parts we could not order before we had the car here to take some measurements on it etc.,” he explains. The build has developed and evolved since the car was delivered in 2022, with new mods being added, and it’s turned into a real beast.
Styling modifications
It’s the imposing exterior that gets your attention first, with that dazzling purple bodywork, but that’s no wrap. You’re looking at Individual Venetian Violet Pearl, and it’s an absolutely sublime shade of silky purple that envelopes the M4’s exterior, changing hue and intensity depending on the light, and it’s simply stunning. We said the G8x was color-sensitive, and purple is definitely a winner in a big way. But shift your gaze from the paint to the rest of the body, and you’ll see the numerous aero additions that give this M4 so much presence and muscle, and it’s with all these aggressive extras that the styling really starts to shine.
“The first time I saw a picture of the M4 GT3, I knew we had to get some similar kidneys for the car, which changes the whole front bumper look. Not long after, Vorsteiner released its kidneys in carbon, which had a similar design, so this was a no-brainer,” explains Viktor. “Besides that, we wanted a nice clean straight front lip in carbon and the carbon air channels for the front. We were pretty satisfied with these parts, to begin with, but then Flossmann contacted us and told us they just finished their first parts for the G82.
CSL influence
They asked us if we had a show car to test the parts on, and we just couldn’t say no to that,” grins Viktor. “So, we got the front fenders, hood and a GT4 rear wing all in carbon from Flossmann that really gave the car a unique look. When the CSL came out later, we thought the trunk lid was really nice, so we changed out the wing on the original trunk to a CSL-style trunk in carbon which we partly painted and left some visible carbon on the spoiler,” and all that combines to make this an awesome-looking machine.
The full carbon grille makes the nose so much more appealing, especially when combined with the angular carbon intakes. Then you’ve got the vented front wings and that carbon bonnet with its power dome and functional vents, all of which immediately transforms the front end of the car. And the rear end is finished off with that stunning CSL-style boot lid, and allowing the carbon weave to show through on the edge of the spoiler lip was an inspired decision.
Chassis modifications on the BMW M4 G82
As we all know, wheels play a crucial part when it comes to a car’s looks, and choosing the right set for this build proved tricky for Viktor and the Schmiedmann team. “The wheels were a real headache to decide on,” he sighs. “When we at first had the APEX VS-5RS 10×19” and 11×19” wheels on, we saw that there was lots of space left. We tried to find if someone else had tried to go up a size but couldn’t find anything,” he shrugs, so they had to be the ones to go for it.
“We measured a few times and decided to custom-order BC Forged wheels for the modified BMW M4 G82. As always, when you custom-order something, we were a bit nervous while waiting for the wheels to arrive,” chuckles Viktor. “We wanted to get as deep and concave wheels as possible, so we ordered the fronts 11” wide with ET-2 and the rear ones 12” wide with ET19. The result was perfect and exactly how we pictured it to be,” he grins, and these wheels were the perfect choice for this G82 build.
The BC Forged LE52 splits have gloss black lips and brushed black centers, with gold bolts breaking up all that blackness, and they absolutely nail the race-style look combined with an elegant finish that Viktor and the team were aiming for. The hefty widths mean they fill out the arches to perfection, and we love the fat sidewalls of the massively wide Nankang AR-1 tires, with 305s up front and 325 rears.
Suspension mods
Naturally, the stock suspension was never going to be suitable for a build with track work in mind, so the chassis has received some upgrades. “We’re currently running KW V4 coilovers and adjustable top mounts. We are waiting for CSL sway bars that haven’t arrived yet, unfortunately,” says Viktor, and those will help to further sharpen the chassis and get the handling even better. “We tried the KW H.A.S. kit at first, but it was not optimal for the track. The KW V4 coilovers are working really great, especially on the Nürburgring,” he explains, so you know they’re doing a good job with praise like that. They’ve also got this M4 sitting perfectly, and it looks so good with that drop.
Engine tuning on the modified BMW M4 G82
The S58 that powers the G8x M duo is an awesome engine that delivers huge power and monster performance out of the box. But with the ability to extract more of that with very little effort, it’s only natural that Viktor and the Schmiedmann team couldn’t help but give the powerplant a little bit of a tweak. “When we ordered the car, we thought we had to do a new tune for it, but after testing it on track, we realized that the power output was much higher than expected,” he grins.
“So we calmed down with unlocking the ECU and tuning it. At first, we just mounted the Supersprint cat-less downpipes and rear silencer, which gave a few extra horsepower. Now we have unlocked the ECU and are running a tune and complete Supersprint Race exhaust, which replaces the OPF and gives a lot of extra power,” smiles Viktor. “We’re satisfied with the power as it is now since it’s made for track and not drag race. But you never know, we might upgrade it more in the future…” he adds with a grin. This M4 isn’t exactly lacking in terms of performance as it is, and it’s making somewhere in the region of 700hp and 700lb ft, which is, let’s be honest, an awful lot.
Interior modifications
Finally, we come to the interior of the modified BMW M4 G82, and while Viktor hasn’t made many changes here, it still looks fantastic from the factory, and there are a few additional touches that just make a difference. “Since we ordered this car new, we, of course, added the carbon bucket seats from the factory. These are perfect for a street/track day car,” explains Viktor, and they are joined by the Carbon Package that slathers the interior in carbon trim. The steering wheel is an M Performance item, with its sexy Alcantara grips, and a Schmiedmann badge replaces the roundel, while the headrests also boast the Schmiedmann script and logo for the finishing touch.
Conclusion
You would expect the CEO of Schmiedmann’s Swedish arm to drive an impressive BM, but even so, this modified BMW M4 G82 takes things to the next level. From its dazzling paintwork to its outrageously sexy carbon additions and menacing wheels, it packs a serious punch in terms of styling and backs that up with its hefty 700hp. This is a serious piece of kit and no mistake, but there are still a few more upgrades left in the pipeline.
“We’ve had the car for a year now, and it’s almost finished, but we plan to keep the car for a few years and might do more modifications to it. It would be nice to get the weight down a bit, but we don’t want to sacrifice the comfort too much – I kind of like that the car can be driven to and from the track, so we don’t want to overdo it either,” reasons Viktor. As it stands, this is a car that will cruise to the ’Ring in comfort, then absolutely monster the track, and get Viktor home again without any stress or fuss. It’s an insanely capable machine, and Viktor and the Schmiedmann crew have put together an absolutely epic M build.
