CMST Ferrari 458 Italia Carbon Aero Kit
The CMST Ferrari 458 aero kit is a carbon-fibre aerodynamic package for the 458 Italia, designed to sharpen the car's airflow and add exposed carbon detailing while preserving its factory shape. It centres on the lower aero surfaces โ a carbon front lip and splitter, side-skirt extensions and a rear lip with a diffuser-style lower section โ formed in dry carbon fibre. The kit is a bolt-on enhancement aimed at refining how air moves around an already aerodynamically considered mid-engine Ferrari.
- Vehicle: Ferrari 458 Italia, 4.5-litre naturally aspirated V8 (mid-engine)

What the CMST 458 aero kit actually is
This is a focused aerodynamic and styling package rather than a widebody conversion. The Ferrari 458 Italia is one of the most aerodynamically resolved cars of its era โ Ferrari developed it with movable front aero elements and an underbody that manages airflow to balance downforce and drag โ so an aftermarket kit for it has to be respectful and precise. CMST's approach keeps the factory silhouette and works the lower aero surfaces, where a well-shaped carbon lip and rear diffuser section can refine airflow without disturbing the car's celebrated proportions. The pieces are formed in dry carbon fibre for the visible weave and a small weight saving. AME lists the kit in the Ferrari body kit range.
The 458's 4.5-litre naturally aspirated V8 sits behind the cabin, driving the rear wheels, and the car is capable of very high speeds. At those velocities, aerodynamic balance front to rear is what keeps a mid-engine car stable, which is why the most useful exterior additions are those that complement the factory aero rather than fight it. A carbon front lip that trims front-end lift and a rear lip that tidies the airflow leaving the tail are sensible, in-keeping upgrades for a car of this calibre.
Piece-by-piece breakdown
Carbon front lip and splitter
The front lip extends the lower leading edge of the 458's bumper, and the front splitter sharpens air management at the very front of the car. Together they reduce the volume of air slipping under the nose, which helps trim front-axle lift and contributes to a more planted front end as speed builds. On the 458, the front aero is critical to the car's balance, so a carefully shaped lip that respects the factory intakes is the right kind of addition โ it refines the existing aerodynamic behaviour rather than overriding it. In carbon, the lip also adds a crisp, dark line to the lower front.
Carbon side-skirt extensions
The side-skirt extensions run along the lower edge of the sills, following the factory skirt line. They tidy airflow along the flanks, visually lower the car and connect the front lip to the rear, giving the side profile a sharper lower line. Because they extend the factory skirts rather than replacing the body shape, they keep the 458's proportions intact while adding carbon detail at eye level.
Carbon rear lip and diffuser section
At the rear, a carbon lip wraps the lower bumper with a diffuser-style lower section that frames the exhaust outlets and the factory diffuser area. Its job is to tidy the airflow leaving the underside and rear of the car and to visually pull the tail toward the road, balancing the sharper front created by the lip. As a bolt-on piece shaped to the factory bumper, it sharpens the rear aero and aesthetics without a full bumper replacement.
Why dry carbon fibre on the 458
Dry carbon fibre is the natural material for a 458 aero kit. It is made by laying pre-impregnated carbon sheets into a mould and curing them under heat and pressure in an autoclave, producing a part that is light, stiff and carries the clean 2x2 twill weave enthusiasts want. For a high-performance mid-engine car, the combination matters: the aero pieces add minimal weight, resist flex at speed so they hold their shape in the airflow, and show genuine carbon weave under clearcoat. On a car as design-led as the 458, exposed carbon at the lower edges is also the most tasteful way to mark it as personalised, because it adds material quality rather than changing the form. The same philosophy runs through AME's carbon fibre body kit range, and you can see CMST's wider catalogue under the CMST collection.
| Aero piece | Primary function | Material |
|---|---|---|
| Front lip and splitter | Reduce air under the nose, trim front-axle lift | Dry carbon fibre |
| Side-skirt extensions | Tidy flank airflow, lower the visual stance | Dry carbon fibre |
| Rear lip and diffuser section | Tidy rear airflow exit, balance the front | Dry carbon fibre |
Fitment and finish
Precise fitment matters on a car like the 458. The front lip and splitter need correct alignment and secure mounting to sit flush against the factory bumper, and their ground clearance should be checked against Australian driveways, speed humps and kerbs at the car's ride height, because a low lip on a low supercar is the part most exposed to damage. The side-skirt extensions and rear lip should follow the factory lines for a flush, integrated result. Dry carbon is stiff and more brittle than factory plastics, so a workshop experienced with Ferraris will protect both the car and the carbon and deliver the clean finish the kit is designed for.
Why carbon aero suits the 458
The 458 rewards restraint. Its shape is widely considered one of Ferrari's best, and its factory aerodynamics are already sophisticated, so the upgrades that suit it are those that refine rather than reinvent. CMST's aero kit does exactly that: a carbon front lip and splitter to sharpen the front, side-skirt extensions to lower the side profile, and a rear lip and diffuser section to tidy the tail, all in dry carbon fibre for weight and weave. It is a coherent package that respects the car's design and aerodynamics while marking it as a personalised 458. For owners who also want carbon inside the glass-covered engine bay, CMST offers matching engine-bay panels, and AME can advise on combining the two.
Frequently asked questions
Does this aero kit fit my Ferrari 458?
The kit is designed for the Ferrari 458 Italia, built 2009-2015. The 458 Spider and the later 488 differ in their bodywork, so confirm your exact model before ordering so the lips and extensions match your bumpers and sills. AME can verify the correct fitment for your car.
Will the kit affect the 458's aerodynamics?
The kit is shaped to complement the 458's factory aerodynamics rather than override them. The front lip and splitter help reduce air under the nose to trim front-axle lift, and the rear lip tidies the airflow leaving the tail, balancing the front. It is a refinement of the existing aero behaviour, designed to keep the car stable and faithful to its proportions, not an extreme downforce conversion.
Is the kit dry carbon fibre?
Yes. The front lip, splitter, side-skirt extensions and rear lip are formed in dry carbon fibre โ autoclave-cured pre-preg carbon with a visible 2x2 twill weave under clearcoat. Dry carbon is light, stiff and holds its shape in the airflow, which is why it suits a high-performance mid-engine car like the 458.
Will a carbon front lip clear Australian driveways?
A front lip and splitter sit low on an already low supercar, so clearance should be checked at your 458's ride height before fitment, with attention to steep driveways, speed humps and kerbs. Your fitter can advise on approach angles for daily use; many owners drive a low lip with awareness of obstacles to protect it.
Can I buy the aero pieces individually?
Yes. The kit is made of discrete components โ front lip, splitter, side-skirt extensions and rear lip โ so you can stage the build. The front lip and splitter make the biggest change to the car's face, while the skirts and rear lip complete the lower line. Contact AME Motorsport to confirm current availability of single pieces for the 458 Italia.
Should the kit be professionally fitted?
Yes. The aero pieces need precise alignment and secure mounting to sit flush, and the front lip's clearance needs assessing for local conditions. A workshop experienced with Ferraris will protect the car and the carbon and deliver the flush, integrated finish the kit is designed for.
If you are adding a carbon aero kit to a Ferrari 458 Italia, AME Motorsport can supply the CMST front lip, splitter, side-skirt extensions and rear lip, and advise on fitment with a Ferrari-experienced workshop. Start with the Ferrari body kit range, then get in touch with your exact model to confirm the right parts.
