Common Applications

The 326POWER Gachabari Medium 1 Front + Rear Fender Set is suitable for S15 Silvia owners who want a coordinated increase in front and rear body width for aggressive wheel fitment, lowered stance, or stronger exterior proportions. The approximately 45 mm front and 55 mm rear increases provide substantially more room and visual width than the standard body while still allowing the use of factory-shaped bumpers and the factory side step. Because the front and rear widths differ, the completed wheel and tire setup should be planned as a complete vehicle rather than choosing front and rear fitment independently. Final compatibility depends on body condition, bumper and side-step configuration, wheel dimensions, tire size, camber, suspension height, steering clearance, rear-quarter preparation, and installation method.

326POWER Character

326POWER is strongly associated with Japanese stance culture, low vehicle setups, aggressive wheel fitment, drift-inspired styling, and distinctive wide-body designs. The Gachabari Medium 1 package gives the S15 Silvia substantially more body width while remaining less extreme than some of the company's larger wide-body conversions. By combining a 45 mm front increase with a 55 mm rear increase, the package creates a noticeably stronger stance while retaining recognizable S15 body lines and compatibility with factory-shaped surrounding components.

Gachabari Medium 1 S15 Design Notes

The Medium 1 package uses different construction methods at the front and rear to suit the S15 body structure. The front fenders are replacement-type components and are designed to follow the original press lines. The rear fenders use a cover-type design over the rear-quarter area. 326POWER specifically states that both are compatible with the original bumper and side-step configuration and that the package can be installed even when the vehicle retains factory bumpers.

45mm Wide Front Fender Design

The front section extends approximately 45 mm farther outward than the factory S15 fender. 326POWER describes the design as working well with the factory press lines, helping the additional width appear integrated into the vehicle rather than looking like a generic bolt-on extension. The wider profile provides more freedom for aggressive front-wheel fitment while also increasing the visual weight of the front body.

55mm Wide Rear Fender Design

The rear section extends approximately 55 mm farther outward than the factory body. Unlike the replacement-style front fenders, the rear components use a cover-type design. This allows the wider rear-quarter profile to be added while retaining compatibility with the factory bumper and side step. The additional 55 mm of rear width creates a stronger rear stance and provides more flexibility when planning wider wheels, tires, camber, and suspension settings.

5mm Raised Rear Arch

The Gachabari Medium 1 rear wheel arch is positioned approximately 5 mm higher than stock. This gives additional clearance around the upper rear wheel area before any further custom arch work is performed. 326POWER also leaves additional material around the arch so installers can raise it further depending on the desired ride height and wheel setup.

30mm Arch Lip Design

Both the front and rear Gachabari Medium 1 wheel-arch areas use an approximately 30 mm lip, compared with approximately 20 mm on the factory S15 fenders. This additional material is intentional. 326POWER explains that the thicker lip allows customers to raise the arch at the desired position while still retaining material around the edge and maintaining balanced proportions.

Additional Arch Raise Capability

The front arch does not have a fixed factory-relative raise specified by 326POWER, allowing the installer to determine the final position according to the build. The rear begins approximately 5 mm higher than stock and can also be raised further. 326POWER gives an example that removing approximately 10 mm from the 30 mm lip can still leave around 20 mm, roughly equivalent to the original factory lip thickness. This allows further customization without immediately removing all of the designed arch edge.

Reinforced Arch Areas

326POWER states that approximately twice the normal amount of FRP material is used around the wheel-arch areas. This additional material is intended to provide strength in the areas most likely to be cut or reshaped during arch raising. It also gives professional installers more material to work with when adapting the fenders for a specific wheel, tire, and ride-height combination.

Factory Bumper and Side Step Compatibility

A major practical feature of the Medium 1 package is compatibility with factory-shaped surrounding parts. 326POWER states that the replacement-type front fenders work with the genuine bumper and side step, and the cover-type rear fenders also support the original bumper and side-step configuration. The international listing additionally states that the package can be installed with genuine bumpers.

Fuel Filler Area

The official Japanese 326POWER listing specifically states that the Medium 1 rear-fender configuration includes a fuel filler lid. Because the combined Front + Rear set contains that rear-fender configuration, the fuel-filler area should be planned as part of the rear installation. However, the international combined-set page does not separately restate the fuel-filler-lid inclusion, so customers for whom this item is critical should confirm the exact supplied set contents before ordering.

Wheel and Suspension Planning

With approximately 45 mm of additional front width and 55 mm of additional rear width, wheel and suspension specifications should be planned together with the bodywork. Wheel width, offset, tire dimensions, camber, suspension height, steering angle, inner clearance, suspension travel, and final arch position can all affect the completed fitment. 326POWER does not prescribe one specific wheel or tire combination for the Medium 1 package, so final specifications should be selected according to the individual S15 and the intended build.

Installation and Fitment Notes

The complete Gachabari Medium 1 Front + Rear Fender Set must be test fitted before painting. At the front, hood gaps, door-side alignment, front bumper transitions, side-step relationships, wheel-arch position, steering clearance, and left-to-right symmetry should be checked. At the rear, the installer should confirm rear-quarter positioning, wheel-arch alignment, bumper and side-step transitions, fuel-filler area, wheel and tire clearance, suspension travel, and overall symmetry. 326POWER specifically requires temporary fitting, gap adjustment, and vehicle-specific alignment before paint. If mounting holes are difficult to align, gradual adjustment such as elongated-hole processing may be required. Additional trimming, sanding, drilling, arch modification, bonding, fabrication, or body finishing may also be necessary depending on the individual vehicle.

Aero Product Notes

The fender set is supplied unpainted in a white gel coat finish, and installation and painting are not included. 326POWER confirms the use of FRP around the arch sections and specifically states that approximately twice the normal amount is used there for reinforcement. All components should be inspected, test fitted, aligned, adjusted, and fully prepared before final painting. Any intended arch raising or fitment modification should also be completed before the final exterior finish is applied.

The fenders are designed to work with factory-shaped bumpers and the factory side step. The product is supplied unpainted in white gel coat and requires test fitting, alignment adjustment, preparation work, and painting before final installation. Other body-kit components, lips, wings, wheels, suspension parts, and accessories shown on demo vehicles are separate unless specifically stated otherwise. 326POWER states that the product was developed for show and event use, does not guarantee vehicle-inspection compatibility, and does not assume responsibility for damage arising from public-road use.
