The CMST Honda Fit aero kit is a mixed-material body kit that pairs FRP bumpers with carbon-fibre detail pieces to give the Fit (Jazz) a wider, more aggressive face. The package combines an FRP front and rear bumper, FRP side skirts and rear arches, and a carbon front lip, carbon grille, carbon fenders and a carbon bonnet. The bonnet uses a vented design that helps the engine bay breathe while taking weight off the nose. It is a styling-led kit aimed at owners who want their small hatch to stand apart on the road.

• Vehicle: Honda Fit (Jazz) hatch
• Material options: FRP (bumpers, skirts, arches, one fender style) and carbon fibre (lip, grille, fenders, bonnet, wing)
• Key pieces: Front bumper, rear bumper, front lip, grille, fenders, side skirts, rear arches, bonnet, rear wing
• Bonnet: Vented carbon design for engine-bay cooling, plus an OEM-shape carbon option
• Finish: Painted FRP bodywork with bare carbon accent panels

What the kit is built to do

The Honda Fit is a practical, light hatch with a keen owner following, and small cars reward visual modification because their proportions change quickly with the right parts. This kit leans into that. Rather than a single lip or spoiler, it reshapes the whole car: new front and rear bumpers change the silhouette, skirts and arches widen the stance, and carbon accents add texture the standard car never had. The intent is a coherent, finished look rather than a collection of bolt-ons.

The material split is deliberate. The large structural shapes — bumpers, skirts, arches — are FRP, which forms big curved panels economically and is made to be painted body colour. The detail and weight-sensitive pieces — lip, grille, fenders, bonnet — are offered in carbon for the weave finish and the weight saving up front. If you are planning a Fit build, AME stocks the full CMST range and the broader Honda body kit collection.

The front end: bumper, lip and grille

The front bumper is the biggest single change. Moulded in FRP, it replaces the factory bumper with a more aggressive design that integrates the new lower intakes and mounting points for the lip. Onto it goes a carbon front lip, which deepens the nose and adds the under-chin shadow that makes a small car look planted. The carbon grille finishes the face with a honeycomb mesh and bare-weave surround that lifts the whole front end. These front pieces sit in the CMST front lip for Honda and CMST bumper for Honda ranges.

Fenders and side profile

The kit offers fenders in two forms: a carbon OEM-shape fender that simply swaps weave for steel, and an FRP fender for builds that want a different profile. Along the sills, FRP side skirts visually drop the car and link the front and rear together. The FRP rear arches widen the rear visually to match the more aggressive bumpers. Because all of these are painted body colour, the FRP choice keeps the cost sensible without affecting the finished look.

The carbon bonnet — cooling and weight

The bonnet is where the kit earns its keep functionally. The signature option is a vented carbon bonnet: the openings let hot air escape the engine bay, which helps under-bonnet temperatures on a hard-working small engine, while the carbon construction takes weight off the highest, most forward part of the car. Removing mass there has an outsized effect on how a light hatch turns in. For owners who prefer a cleaner look, there is also an OEM-shape carbon bonnet without vents that keeps the factory profile but adds the weave and the weight saving. Both are listed under CMST hood for Honda.

The finished look on the road

Assembled and painted, the kit transforms the Fit's proportions. The deeper front bumper and lip stretch the nose, the skirts and arches widen the stance, and the carbon bonnet, lip, grille and fenders break up the paint with bare weave. On a bright body colour such as red, the contrast between gloss paint and matte-edged carbon is what gives the car its presence — the eye is pulled across the front lip, up to the bonnet vents and along the skirts rather than seeing one flat shape. A carbon rear wing completes the package at the back, tying the roofline into the rest of the build.

FRP and carbon: choosing per panel

This per-panel approach is common on small-car kits: spend the carbon budget where weight and weave matter most (the front and the bonnet) and use FRP for the big painted shapes. It keeps the overall cost in check while still giving the car a genuine carbon presence.

Frequently asked questions

Is this kit carbon fibre or FRP?

It is both, by design. The bumpers, side skirts and rear arches are FRP and are painted to match your car's colour. The front lip, grille, fenders, bonnet and rear wing are available in carbon fibre for the weave finish and the weight saving. You can mix the materials to suit your budget and the look you want.

What is special about the vented bonnet?

The vented carbon bonnet has openings that let hot air escape the engine bay, which helps keep under-bonnet temperatures down on a small, hard-working engine. It also saves weight at the front of the car compared with the steel original. If you prefer the factory shape, there is an OEM-style carbon bonnet without vents.

Will the FRP pieces need painting?

Yes. The FRP bumpers, skirts and arches arrive primed and must be sprayed to match your car's colour, including any metallic or pearl, so they blend into the body. Budget for a painter who can match the factory Honda colour as part of the install.

Does this kit make the car wider?

The new bumpers, skirts and rear arches give the Fit a visually wider, more aggressive stance. It is a styling-focused kit rather than a full widebody track conversion, but the proportions change noticeably once everything is fitted and painted.

Can I buy just the carbon pieces?

Yes. The kit is made up of separate components, so you can take only the carbon front lip, grille, fenders or bonnet if you want to add carbon detail without changing the bumpers. The Honda-specific collections list the pieces individually so you can stage the build.
