When BMW revealed the G80 M3 and G82 M4, nobody talked about the S58 or the chassis. They talked about the nose. Six years on the argument has calmed down, and the choices have settled into four: leave it alone, keep the factory bumper and change the carbon around it, swap to ADRO's V1 bumper, or swap to the new ADRO V2.
We've built cars down each of these routes. Most recently, a red G82 M4 came down from Scotland for the full ADRO V2 front end, plus a rear diffuser, side skirts and some protection underneath. This is what we learned from it, and how we'd choose between the four if it were our car.
G80 M3 and G82 M4 front bumper options compared
| Factory bumper | Factory bumper with carbon parts | ADRO V1 bumper | ADRO V2 bumper | |
|---|---|---|---|---|
| How it looks | BMW's design | BMW's design, sharper detail | A new design altogether | BMW's design, wider and lower |
| What changes | Nothing | Kidney grilles, side ducts, splitter | The whole bumper | The whole bumper |
| Paintwork | None | None for the carbon parts | Body colour if your bodyshop paints it | Arrives unpainted, so painting is part of the job |
| Going back | Nothing to undo | Easy: refit the original trims | A bumper swap | A bumper swap |
| Splitter | Factory-bumper splitters | Factory-bumper splitters | ADRO V1 splitter | ADRO V2 splitter only |
| Worked example | Ross's G80 M3 | Our ADRO V1 G82 build | This car |
The useful way to read that table is from left to right, as a scale of how far you want to move away from what BMW drew. The further right you go, the more the car changes and the more work it takes to go back.
Keeping the factory bumper, with or without carbon
Plenty of owners who disliked the G8X front end in 2020 have come round to it. It's the only option with nothing to paint and nothing to reverse, and on a car you might sell in a few years that counts for something. If you like the face but want the car to sit better, spend the money on stance first. Our G80 M3 and G82 and G83 M4 ranges are the place to start.
The next step is the one most owners take. You keep BMW's bumper and change the three areas that give it character: the kidney grilles, the side ducts and the splitter. Swap one and the car looks a little sharper. Swap all three and it can look like a different specification of M4.

That's how the red car arrived: a CSL-style grille, M Performance-style ducts and a Vorsteiner-style splitter. We don't know who made those parts, so we won't call them genuine. For a full version of this route using parts we sell, Ross's G80 M3 build keeps the factory bumper and adds carbon from FORM and TREVORA.
We'd recommend this route to anyone who isn't sure. It's the one choice on the list you can undo on a driveway in an afternoon, and the car never stops looking like it came from BMW. Its limit is that the shape underneath stays BMW's. If the proportions of the nose are what bother you, carbon trim won't fix them.
ADRO V1 vs V2 front bumper: what's different
ADRO's V1 front bumper arrived about a year after the car and replaced BMW's design outright. As we said in the film, it "converted a lot of G8X haters into lovers". It also split opinion, because by then a good number of owners had started to like the factory face, and the V1 asked them to give it up.
The V2 goes the other way. In the film we put it like this:
"The V2 front bumper stopped trying to replace BMW's design, but instead refined BMW's design."

Stand in front of it and it's still unmistakably a G80 or G82. The kidney grilles and headlights are BMW's, and ADRO's listing describes the V2 as integrating more closely with both. What has changed is everything around them. The intakes are wider and sharper, and the lower section sits lower and broader, so the car looks planted rather than tall. ADRO's listing also says no headlight modification is needed, which matters if you'd rather not touch BMW's expensive lights.
| ADRO V1 | ADRO V2 | |
|---|---|---|
| Design approach | Replaces BMW's front end | Refines BMW's front end |
| Material | TPO plastic | Injection-moulded polypropylene |
| Still reads as a G8X? | Not really, and that's the point | Yes |
| Matching splitter | V1 splitter | V2 wet carbon splitter, which needs the V2 bumper |
| Worked example | Our ADRO V1 G82 build | This car |
So which one? If you never liked the car's face and want people to know it's been changed, the V1 is still the bolder statement. Our V1 G82 and the Ireland-to-Essex G82 M4 show how far it can take the car. If you like the M4 and want the front to look finished, the V2 is the better choice, and we think it's the one that will age better. Parts don't cross over, so this is a decision to make once. A V1 splitter, grille or duct is made for the V1 bumper only.
You don't need ADRO's V2 bonnet for either the bumper or the splitter. The V2 dry carbon bonnet is there if you want to go further, but the red car kept its factory bonnet, and we think the front looks right without it.
What fitting an ADRO V2 front bumper involves
This is the biggest job on the list, and we don't think it's a driveway job. On camera we said you could do the whole kit at home if you really wanted to. Most of it, yes. The bumper is different. The listing recommends professional installation, because a bumper swap on a G8X means working around the front crash structure, the sensors and the cooling connections. We agree, and we fit them at our workshop.
It helps to know what arrives. The V2 bumper is injection-moulded polypropylene, the same family of plastic most car makers use for their own bumpers. In the box with it come a plastic centre grille, a pair of plastic duct vents, two radar meshes (one with the frame for the adaptive cruise radar and one without, so you use whichever matches your car), a foam energy absorber and the fixings. That foam absorber matters: ADRO says the factory one isn't compatible with the V2, which is why one comes in the box. If you want carbon in the grille and duct openings, those are separate ADRO parts.
The sequence is straightforward. The wheels come off, then the arch liners, then the top and bottom bolts, and the factory bumper comes away. Before the ADRO V2 front bumper goes on, everything moves across from the old one: the parking sensors, the wiring harness, the sensor brackets and the small brackets that hold the bumper to the wings.

Paint is part of the job, not an extra. The bumper arrives unpainted and ADRO recommends professional paintwork, so plan for it from the start and have it painted before fitting day, not after. On our build, our paint shop colour-matched the bumper and it was ready to fit by the time it reached the ramp. The trick we use for an exact match is to ask the owner to send in the fuel filler flap, which gives the painter a perfect sample of the car's paint as it is today, after a few years in the sun. It works just as well with your own bodyshop. A good painter will also want time to prep a new plastic bumper properly, and that prep is what decides whether the finish matches the wings beside it.
The V2 splitter, and protecting the oil cooler first
Before the splitter goes on, look underneath. On every G8X the oil cooler and its lines sit low and exposed behind the bumper. At standard ride height that's rarely a problem. Lower the car and it becomes one. One of our team hit a large rock on a trip to Switzerland in his own M4, before he'd fitted a guard, and came very close to splitting a line. A damaged oil cooler on an S58 is not a repair anyone wants.

The TREVORA oil cooler skid plate is a 5052 aluminium plate, powder-coated, that replaces the factory plastic undertray. Fitting it means swapping over the clips that the 10 mm fixings screw into, removing the old tray and bolting the new one up. If your car is lowered, or you plan to lower it, we'd fit one regardless of which bumper you choose.
Then the splitter. The ADRO V2 carbon splitter is wet carbon fibre, and it needs the V2 bumper. It won't fit the factory bumper or the V1. It fits like most splitters. Clean the mounting face with an adhesive wipe, put 3M tape on the splitter, line it up and let the tape hold it, then fix it across its width with the self-tappers ADRO supplies.

We wouldn't fit the V2 without it. The bumper's lower edge is drawn to carry the splitter, and the two together are what make the front look wider and lower. With the splitter on, it's what we called "a night and day difference over the stock look."
Matching the rear: the ADRO V2 diffuser
A wider, lower front can leave the back of a G8X looking a little plain, so the owner added the ADRO V2 pre-preg carbon rear diffuser. Casper's view of the job:
"This is probably the easiest thing to install on a G series."
He wasn't exaggerating. The factory diffuser is held by two push clips underneath, and the rest is pop clips. This one practically fell out. The ADRO part pushes into place, and the centre fixings tighten with an Allen key. Our car also needed small holes at the corners, drilled with a 5 mm bit, for a nut and bolt each side. Check yours before you start.


The diffuser sits further out around the tailpipes than the factory part, and the rear looks fuller for it. Casper said off camera that the back end looked like it had had a bit of Botox, which is fair. There's one side effect. With the wider diffuser, the factory tips now look slightly tucked in, and larger tips would fill the gap. That's the next job we'd suggest to this owner.
Side skirts, mirror covers and badges
None of these needs a ramp or a paint booth, and all three make the bumper look like part of a plan.
The FORM pre-preg carbon side skirts replace the gloss black trims along the sills. Those trims are normally held by push clips underneath, but this car had none, which suggests it had different skirts at some point. We fitted new plastic push clips of the original type so the FORM skirts sit tight. FORM says the skirts use all the factory mounting points. The detail we like most is the winglet at the front of each skirt, which lines up with the winglet on the V2 splitter. The fixings differ from the TREVORA PR-1 skirts in our ADRO V1 G82 build, so follow the instructions for whichever skirts you choose.

The TREVORA pre-preg carbon mirror covers replace the factory black covers rather than sticking over them. The official way to swap them is to remove the mirror glass, press two clips and lift the cover off. The risk is the glass. As Casper put it, the units aren't cheap
"because they're heated and they have lane assist"
and the motor behind the glass is easy to upset. Our technicians use a quicker method: a firm grip on the top of the cover and one quick, hard pull, which releases the clips without going near the glass. The indicator then moves across and the TREVORA cover clips on. If you're not confident, use the remove-the-glass method. It takes longer and it's the safer choice.

The BMW M Performance Heritage 50 Years badges were the owner's idea, to match the 50th anniversary centre caps already on his wheels. Tape around the old badge, prise it off and clean away every trace of adhesive. On the boot, the badge houses the reversing camera, so make sure the camera sits flush before you close it up. When you order, pick the right chassis. The M4 G82/G83 rear badge comes with or without the reversing camera cut-out, so check which your car has.
The finished red G82 M4
It still looks like a G82 M4, and that's the point. The front is wider and lower, the intakes are sharper, and the carbon at the sides and rear ties it together. To anyone who doesn't know G8Xs well, it looks as if it left the factory like this.
Asked what he thought, the owner kept it short:
"I love it."
His favourite part was the bumper at the front. Then he drove it back to Scotland.
Would we do anything differently? Only the exhaust tips. We'd also say this to anyone weighing up the V2: buy it as a front end, not just a bumper. The splitter is what finishes the look, the oil cooler guard is simple insurance once the car is low, and the rear diffuser stops the back looking like an afterthought.
ADRO V2 build list and G80, G81, G82 and G83 fitment
| Part | Brand | What we noted fitting it |
|---|---|---|
| V2 front bumper | ADRO | Polypropylene, arrives unpainted; painted to match before fitting; professional fitting recommended |
| Carbon splitter for V2 bumper | ADRO | Wet carbon fibre; 3M tape and self-tappers; needs the V2 bumper |
| V2 pre-preg carbon rear diffuser | ADRO | Our car needed small corner holes for a nut and bolt |
| Pre-preg carbon side skirts | FORM | New push clips fitted |
| Pre-preg carbon wing mirror covers | TREVORA | Replaces the factory covers |
| Oil cooler skid plate | TREVORA | Worth it once the car is lowered |
| Heritage 50 Years badges | BMW M Performance | Check the reversing camera option |
Nearly every part on this car fits all four G8X bodies, with a variant to choose on some. ADRO confirms the V2 bumper and splitter for the G80 M3 and G82 M4, including the 2024-on LCI cars, and for the G81 Touring and G83 Convertible. It doesn't yet confirm the facelifted G81 or G83, so if yours is an LCI Touring or Convertible, ask us before you order. The Touring suits the V2's approach well, a car that already looks purposeful made a little more finished, and the V2 diffuser fits the G81 Touring as well.
