Evo 8/9 Carbon Fiber Body Parts Compared (2003-2007)

Carbon fiber body parts for the 2003-2007 Mitsubishi Lancer Evolution VIII and IX are the fastest way to shave weight off a chassis that already punches far above its class. The CT9A Evo runs a nose-heavy 2.0L 4G63T turbo engine and a full Super-AWD driveline, so every pound you pull off the hood, trunk, doors and fenders lands exactly where the car wants it gone. In our Tampa, FL shop we get asked constantly which Seibon panel to buy first – so we lined up the entire Evo 8/9 carbon fiber body catalog, compared construction, fit and price, and picked the winners.

Why Carbon Fiber Makes Sense on a CT9A Evo 8/9

Carbon fiber is roughly 40–60% lighter than the equivalent steel panel because carbon composite has a density near 1.5 g/cm³ versus about 7.85 g/cm³ for steel. On a 2003-2005 Evo VIII (US curb weight around 3,240 lb) or a 2006-2007 Evo IX (around 3,285 lb), that translates into real, measurable weight loss on the exact panels that hurt handling most.

The Evo VIII makes 271 hp and 273 lb-ft from the 2.0L 4G63T, while the MIVEC-equipped Evo IX bumps that to 286 hp and 289 lb-ft – but both carry that turbocharged iron-block four ahead of the front axle line. Replacing the heavy factory steel hood with carbon takes weight off the highest, most forward point of the car, which lowers the center of gravity and reduces front-axle load. Do the trunk, doors and fenders too and you pull mass from the corners, sharpening the AYC-managed rotation the Evo is famous for. This is why Time Attack and track-day CT9A builds almost always run carbon panels.

Seibon Carbon Explained: OEM vs OEM-DRY vs CW

Seibon, founded in 2003, is a dedicated carbon fiber specialist, and its Evo 8/9 lineup comes in three constructions that matter to your wallet and your weight target:

OEM (wet-layup carbon)

Seibon's "OEM" line is a hand-laid, wet-layup carbon skin over a fiberglass substrate, finished in a glossy UV-protective clear coat with a 2x2 twill weave. It keeps the factory shape and is the most affordable way into real carbon – the Evo 8/9 OEM hood is just $1,170. It is lighter than steel but heavier than full dry carbon.

OEM-DRY (dry carbon)

"OEM-DRY" is pre-preg dry carbon cured in an autoclave – the same process used for aerospace and motorsport parts. It is both lighter and stiffer than wet-layup carbon because there is no fiberglass backing and far less resin. It is the premium choice: the OEM-DRY hood runs $2,700 and the OEM-DRY trunk lid is $2,340. If your goal is maximum weight loss, dry carbon is the answer.

CW (vented / cowl style)

The "CW" hood is a vented, aggressive-styling wet carbon hood with functional heat-extraction vents – ideal for a big-turbo 4G63 that soaks the engine bay in heat. At $1,350 it is the enthusiast's cooling-and-style pick.

Evo 8/9 Carbon Hoods Compared: Which One Wins?

The hood is the single best carbon fiber upgrade for a 2003-2007 Evo 8/9. All three Seibon hoods fit the 03-07 Evo VIII and IX (CT9A) and mount to the factory hinges, but they serve different buyers. The OEM-DRY hood is the weight king; the OEM hood is the value play; the CW hood adds vented cooling.

Carbon Doors, Trunk Lids & Wider Fenders

Once the hood is done, the doors, trunk and fenders are where a serious CT9A build pulls the rest of its weight. Seibon's carbon doors are the halo piece of the Evo 8/9 catalog and, at $3,420 per set, the most expensive panels here – but they replace the heaviest bolt-on body parts on the car.

Seibon also offers matching carbon fiber rear doors ($3,420) so you can convert all four openings on your four-door Evo. The doors are the priciest panels in the catalog for a reason: the factory Evo doors are heavy stamped-steel assemblies, and replacing all four skins removes the most bolt-on mass of any single upgrade. You still transfer your OEM glass, window regulators, latches and mirrors, so the car keeps working windows and locks – these are a weight-reduction and show-build piece, not a stripped-out race conversion.

For the tail, you get three trunk options: the featherweight OEM-DRY dry-carbon trunk lid ($2,340), the ducktail-style CSL-style trunk ($1,260) for a built-in lip, and the wet-layup OEM trunk ($1,170) for the budget-minded.

The 10mm wider carbon fenders are the CT9A fitment cheat code: they add 10mm of clearance per side over the factory steel fenders, letting you run wider wheels, more aggressive offsets or taller semi-slick tires without rubbing – while swapping steel for carbon at the same time.

Finishing pieces round out the look: the OEM carbon rear spoiler ($855) and a choice of front lips including the Evo IX RA-style front lip ($855).

How Much Weight Can You Actually Save?

A full carbon fiber conversion on an Evo 8/9 can realistically strip 40–70 lb from the car, depending on which panels you run and how you finish them. Because carbon composite weighs roughly one-fifth as much as steel by volume, each panel gives up meaningful mass: a carbon hood typically saves around 10–15 lb versus the factory steel unit, a carbon trunk around 8–12 lb, and full carbon doors the largest single reduction. Exact figures vary with the hardware you transfer over (latches, glass, regulators), so weigh your old panels before and after if you want hard numbers.

The value is not just total weight – it is where the weight comes off. Hood, fenders and doors all sit high or far from the car's center, so removing that mass lowers the polar moment of inertia and helps the Evo change direction faster. For an autocross or Time Attack CT9A, that is worth more than the same weight pulled from the trunk floor.

Fitment & Installation Notes

All of these panels are built for the CT9A chassis – the 2003-2005 Evo VIII, 2005 Evo VIII MR, and 2006-2007 Evo IX. The hoods, trunk lids, spoiler and fenders are cataloged for 2003-2007, and the carbon doors carry a 2003-2008 Evo VIII fitment. They bolt to factory hinges and hardware, but carbon body panels are a trim-and-fit job: plan for test fitting, hood pins on the hoods, and transferring latches, glass and regulators on the doors and trunk. We recommend professional installation and a proper alignment of gaps before final torque.
