The best BMW M5 G90 body kit should do more than add carbon. It should make the new M5 look sharper, more planted, and more complete without taking away its street usability. The G90 is not just a faster 5 Series. It has new proportions, stronger body lines, and different fitment demands from the older F90, so not every upgrade belongs on this car. This guide explains what to check before you buy, how the G90 Sedan differs from the G99 Touring, and why a complete carbon fiber Street Program is often the cleanest choice.
What Makes a BMW M5 G90 Body Kit Worth Buying?
A BMW M5 G90 body kit is worth buying when it improves proportion, fitment, and material quality at the same time. The factory M5 already has the power: BMW lists the M5 Sedan at 717 hp and 738 lb-ft of torque. The exterior upgrade should feel just as considered. A well-designed kit gives the car more presence while keeping the executive character that makes an M5 different from a coupe or track build.

Why the G90 Platform Deserves a Premium Body Kit
The G90 is the first M5 built on BMW's newer CLAR platform with a longer wheelbase, wider stance, and completely different body lines from the F90. That means the proportions are different, the panel gaps are different, and the way light hits the car is different. A cheap or poorly fitted kit will stand out in a bad way. A premium body kit, especially one designed around dry carbon fiber and proper OE-level fitment, works with the car instead of against it.
RevoZport builds its Street Program specifically for this platform. The parts are not repurposed from older models or generic molds. They are shaped to match the G90's actual body lines, which is why the finished look feels complete rather than bolted-on.
What to Look For: Fitment, Materials, and Daily Usability
Before you choose a BMW M5 G90 body kit, check three things:
-
Fitment: The kit should be designed for the G90 Sedan or G99 Touring, not adapted from another model. Small gaps around the hood, bumper corners, or diffuser are easy to see on a car at this level.
-
Materials: Dry carbon fiber gives sharper edges, cleaner surface definition, and better long-term shape stability than lower-grade carbon construction.
-
Street Usability: A good street kit should add presence without making normal roads, parking ramps, and driveway angles feel like a compromise.
What Body Kit Differences Matter Between the BMW M5 G90 Sedan and G99 Touring?
The main body kit difference between the BMW M5 G90 Sedan and G99 Touring is the rear spoiler. RevoZport’s Street Program uses the same core front, side, and lower-rear logic across both models, but the Sedan uses a trunk spoiler while the Touring uses a roof spoiler.

Platform Differences That Affect Body Kit Fitment
The front end, hood, front bumper zones, side skirts, lower rear diffuser area, and rear bumper corners all use the same Street Program structure for both the G90 and G99. The front lip strengthens the lower visual base. The air vents and canards add structure to the bumper corners. The hood gives the front more tension and a stronger M identity. The side skirts visually lower the body and connect the side profile. The rear diffuser adds depth to the lower rear, and the rear canards define the bumper corners.
The main split happens at the rear spoiler. The G90 Sedan uses a trunk spoiler that mounts on the rear deck. The G99 Touring uses a roof spoiler that follows the longer roofline and wagon tailgate. These two components are not interchangeable. If you order the wrong one, it will not fit.
Wheel arches are also different in concept. The current Street Program does not include separate widebody arch replacements, so wheel width and arch fitment are not a deciding factor here.
Choosing the Right Body Kit for Your M5 Variant
If you drive a G90 Sedan, your spoiler choice is the trunk-mounted version. If you drive a G99 Touring, you need the roof spoiler. Everything else in the kit, front to back, fits both variants. Before you order, confirm your model year, market specification, and whether your car has optional equipment like ACC, a 360-degree camera, or parking sensors. These options can affect how front and rear carbon parts install, especially around sensor and camera zones.
Which BMW M5 G90 Body Kit Option Is Right for You?
Not every buyer wants the same thing. Some want a full transformation. Others want something subtle. Here is how the main categories break down.
Best Overall: Complete Carbon Fiber Street Program
A complete Street Program is the best overall choice because it treats the car as a system, not a collection of random parts. Every piece is designed to work together. The front lip, air vents, canards, hood, side skirts, rear diffuser, rear canards, and spoiler all follow the same visual language. The result is a car that looks finished rather than modified.
The RevoZport BMW M5 G90 / G99 Street Program uses dry carbon fiber with a Toray 2x2 woven finish. That gives you consistent surface quality across every panel, which is critical on a large sedan where transitions between parts are easy to spot.

Best for Aggressive Looks: Widebody Kit
If you want maximum visual impact, a widebody-style build gives the car a broader stance and a more dramatic profile. It can work for show-focused builds, but it often needs wheel, tire, suspension, and clearance planning to look correct. For the current RevoZport M5 G90 / G99 Street Program, the direction is different: sharper carbon aero, not a full widebody conversion.
Best for Subtle Daily Use: OEM-Style Aero Kit
An OEM-style aero kit keeps the factory look but adds sharper definition. Think of it as a refined version of the stock body. The changes are noticeable up close but do not scream for attention from across a parking lot. This works well if you want a cleaner, more planted look without drawing too much attention.
Best for Track-Inspired Builds: Functional Aero Kit
Functional aero kits prioritize downforce and airflow over pure looks. These kits include components like larger splitters, dive planes, and diffusers that are shaped in wind tunnels or through CFD analysis. RevoZport uses CFD-tested designs in its Race Program, so if track performance is your goal, that direction makes more sense than a pure Street Program.
How to Choose the Right Body Kit for Your M5 G90?
Buying a body kit is not complicated, but it is easy to get wrong if you skip the basics. Here is the decision process we recommend.
Confirm Your M5 Generation and Variant (G90 vs G99)
This sounds obvious, but double-check. The G90 is the Sedan. The G99 is the Touring. They share most components, but the spoiler is different, and rear fitment depends on your body style. Also confirm your model year and market. A US-spec car may have different bumper and lighting configurations compared to a European or Asian market car.
Choose Standard Aero or Widebody Based on Your Driving Needs
Ask yourself where you drive most. If your daily route includes city streets, parking garages, and highway cruising, a standard aero kit or Street Program is the smarter play. If you mostly drive on open roads, attend car shows, or want a track-day look for the street, a widebody kit gives you that aggressive stance. Just remember that wider fenders and lower lips change how the car behaves in tight spaces.
Compare Materials: Dry Carbon vs Wet Carbon vs ABS
Dry carbon fiber is the premium option. It is lighter, stronger, and holds dimensional stability better over time. It also allows sharper edges and cleaner surface finishes. RevoZport uses dry carbon with Toray pre-preg material and autoclave curing.
Wet carbon fiber is more common in lower-priced kits. It is heavier and tends to have softer edges. It still looks good, but it does not match the precision of dry carbon.
ABS plastic is the budget choice. It is easier to produce and repair, but it lacks the visual depth and structural rigidity of carbon fiber. For a car like the M5, ABS usually looks out of place.

Check Fitment and Installation Requirements
Every component in the Street Program has its own installation complexity. Here is what to expect.
Front lip installation is rated medium difficulty and takes about 1.5 to 2.5 hours. It requires correct alignment to the lower front bumper and a ground-clearance check. Air vents and ducts are medium to high difficulty, around 2 to 3 hours, and may require partial bumper disassembly. Sensor and duct clearance must be verified. Front canards are low difficulty at 1 to 1.5 hours. Hood replacement is high difficulty, 2.5 to 4 hours, and requires checking hood gaps, hinges, latches, and washer lines. Side skirts are medium difficulty, 2 to 3 hours, and need stable fixing points. Rear diffuser is high difficulty, 3 to 5 hours, and requires checking exhaust clearance, parking sensors, and PDC. Rear canards are low difficulty at 1 to 1.5 hours. The G90 trunk spoiler or G99 roof spoiler is low difficulty, 0.75 to 1.5 hours, but requires clean surface prep and precise centering.
A complete Street Program takes roughly 10 to 16 hours of professional installation. If you also want PPF, ceramic coating, or sensor recalibration, plan for 1 to 2 working days.
Small add-on parts like canards or spoilers can be handled by experienced DIYers. The full kit, especially the hood and rear diffuser, should be installed by a professional body shop.
Consider Ground Clearance and Daily Road Conditions
Before you commit, measure your current ride height and think about your local roads. A front lip that looks perfect in photos can become a daily headache if you have steep driveways, speed bumps, or rough pavement. The Street Program is designed with street usability in mind, so ground clearance is better than most race-focused kits. Still, check the numbers before you buy.
Why RevoZport's G90 Street Program Is a Strong Choice?
RevoZport stands out because its G90 / G99 Street Program is designed as a complete exterior system, not as isolated trim pieces.

Designed as a Complete System, Not Random Parts
The Street Program is not a catalog of parts you pick and choose from. It is a unified design. RevoZport looked at what the factory G90 was missing and built a kit that fills those gaps without breaking the original design language.
The factory front face is too calm for a new-generation M5. The lower front does not carry enough visual weight. The side profile needs a stronger lower line to control the size of the car. The rear diffuser area looks flat and disconnected. The rear needs stronger structure to match the size and power. RevoZport addresses each of these weaknesses with parts that feel like they should have been there from the start.
Carbon Fiber Construction for a Premium Upgrade
RevoZport uses dry carbon fiber with Toray 2x2 woven material. That is the same grade of material used in motorsport and aerospace applications. The autoclave curing process ensures dimensional stability, which means the parts fit properly and stay that way over time. On a large performance sedan where every panel edge is visible, that level of precision is non-negotiable.
Fitment Designed for the G90 Platform
These parts are not adapted from another model. They are designed using 3D scanning and CAD modeling of the actual G90 and G99 platforms. That means the hood lines up with the factory hinges. The bumper parts match the stock mounting points. The side skirts follow the original body contours. You are not forcing something to fit. It is built to fit.
Built for Street Usability and Performance Style
This is not a race-only kit, and it is not an exaggerated widebody conversion. It is a Street Program for a large executive performance car that needs to look more serious, more planted, and more complete without becoming fake or overdone. You can still daily drive it. You can still park it. You just get the visual authority the M5 should have had from day one.
Frequently Asked Questions
Q: Is a carbon fiber body kit worth it for a BMW M5 G90?
A: Yes, if you care about fitment, surface quality, and a premium exterior finish. Dry carbon fiber gives the G90 sharper edges and cleaner panel definition than lower-grade materials. For a car in this class, the kit should look integrated with the factory body, not like an added accessory.
Q: What is the difference between an aero kit and a widebody kit?
A: An aero kit adds functional or stylistic airflow components like front lips, side skirts, and rear diffusers without changing the car's overall width. A widebody kit extends the fender arches and adds width, which usually requires wider wheels and suspension adjustments. Aero kits are better for daily driving. Widebody kits are better for show or track-focused builds.
Q: Will a G90 Sedan body kit fit a G99 Touring?
A: Most of it will, but not everything. Front lips, hoods, side skirts, rear diffusers, and canards are shared between the G90 and G99. The spoiler is not. The G90 uses a trunk spoiler. The G99 uses a roof spoiler. These are not interchangeable. Always confirm your exact variant before ordering.
Q: Which BMW M5 G90 body kit is better for daily street driving?
A: A Street Program or OEM-style carbon aero kit is the better daily-driving choice. It adds stance and detail without pushing the car into a race-only setup. For the G90, that means checking ground clearance, sensor areas, driveway angles, and spoiler fitment before choosing the full kit.
Conclusion
The right BMW M5 G90 body kit should make the car look more resolved, not more crowded. Start with your exact variant, then check material quality, fitment, installation path, and daily road clearance. Dry carbon is the premium choice when you want crisp edges, stable shape, and a finish that suits a six-figure M car.
RevoZport has built carbon fiber body kits and aero solutions since 2005. The BMW M5 G90 Street Program follows the same approach: dry carbon construction, clean fitment logic, and a design that respects the original M5 shape while giving it a stronger street presence.
