Common Applications

The 326POWER Gachabari Medium 2 Front + Rear Fender Set is suitable for S15 Silvia owners who want substantially more room and visual presence around the wheels while maintaining an equal nominal width increase at both ends of the car. It works particularly well for lowered street builds, aggressive wheel fitment, stance projects, drift-inspired cars, show vehicles, and other Japanese tuning-style builds. Final compatibility depends on body condition, bumper and side-step configuration, wheel dimensions, tire size, suspension height, camber, steering clearance, arch modification, and installation method.

326POWER Character

326POWER is closely associated with Japanese stance culture, aggressive wheel fitment, very low vehicle setups, drift-inspired builds, and distinctive wide-body styling. Gachabari Medium 2 takes a more balanced approach than Medium 1 by using approximately 45 mm of additional width at both the front and rear. 326POWER describes this reduced and equal projection as creating a more natural finished appearance while still giving the S15 considerably stronger proportions.

Gachabari Medium 2 S15 Design Notes

The Medium 2 package uses different construction methods at the front and rear. The front is a replacement-type fender that works with the S15's existing press lines, while the rear is a cover-type fender shaped around the press line running from the door. Both are designed to work with factory-shaped bumpers and the factory side-step configuration, allowing the vehicle to gain considerable width without automatically requiring replacement surrounding aero.

45mm Front Fender Design

The front fenders increase width by approximately 45 mm compared with stock. They use a factory-replacement configuration and have no preset arch raise, giving the installer flexibility to determine the final wheel-arch position according to the individual wheel, tire, suspension, and ride-height setup.

Deep Front Fender Duct

One of the most distinctive Medium 2 details is the depth of the front-fender duct. 326POWER states that the duct has been carved as deeply as possible while working with the original press lines, creating an unusually deep and aggressive shape. This gives the fender significantly more visual character than a simple widened replacement panel.

Lowered Turn-Signal Position

The turn-signal position has also been lowered as part of the Medium 2 design. According to 326POWER, this was done to make the vehicle appear visually lower. Because the indicator position differs from the factory arrangement, its positioning and installation should be carefully checked during test fitting.

45mm Rear Fender Design

The rear fenders also add approximately 45 mm of width compared with stock. Unlike the front replacement panels, the rear uses a cover-type construction that follows the press line extending from the door. This allows the wider quarter-panel shape to blend more naturally into the existing S15 body while maintaining the same nominal width increase as the front.

5mm Raised Rear Arch

The rear wheel arches are positioned approximately 5 mm higher than the factory location. This provides additional clearance around the upper wheel area even before any further custom arch modification is carried out. The front, by comparison, has no preset arch raise.

30mm Arch Lip and Additional Adjustment

326POWER sets both front and rear wheel-arch lip areas at approximately 30 mm compared with roughly 20 mm on the factory fenders. At the rear, this approximately 30 mm thickness is maintained even after the initial 5 mm arch raise. The manufacturer explains that around 10 mm can be removed while still leaving approximately 20 mm, giving installers useful flexibility when raising the arches further for a particularly low or aggressive wheel setup.

Reinforced Arch Areas

Approximately twice the normal amount of FRP material is used around the front and rear wheel-arch areas. This reinforcement is specifically intended to provide additional strength and usable material when the arches are cut or reshaped. It is particularly useful on builds where wheel diameter, tire clearance, suspension height, or aggressive fitment requires additional arch modification.

Rear Fender Mounting Design

The rear fender has a folded section along its mounting surface that allows double-sided tape to be applied. 326POWER describes this detail as helping the cover-type rear fender achieve a more natural finished appearance against the original body. Proper test fitting and secure installation are still required.

Factory Bumper and Side Step Compatibility

Both the front and rear Medium 2 fenders are designed to work with factory-shaped bumpers and the factory side step. 326POWER specifically states that when the front bumper retains the original shape, the bumper and wider front fender are designed to meet correctly. The complete Medium 2 configuration can therefore be used while retaining the genuine bumper arrangement.

Fuel Filler Area

The Medium 2 rear fender is designed to reuse the factory fuel filler cap rather than supplying a completely new cap. An extension stay for the fuel-filler catch is included to accommodate the wider rear-fender position.

Medium 2 vs. Medium 1

The main difference between the two Gachabari Medium configurations is the rear width. Medium 1 uses approximately 45 mm of additional width at the front and 55 mm at the rear, while Medium 2 uses approximately 45 mm at both ends. Medium 2 therefore creates a more even front-to-rear wide-body proportion, while Medium 1 gives the rear a slightly stronger width bias.

Wheel and Suspension Planning

With approximately 45 mm of added width at both ends, the wheel and suspension setup should be planned together with the fender installation. Wheel width, offset, tire dimensions, camber, steering angle, suspension travel, ride height, and final arch position can all influence the finished fitment. Because the front arches can be raised according to the build and the rear arches already begin approximately 5 mm higher than stock, any additional arch modification should be planned before painting.

Installation and Fitment Notes

The complete Front + Rear Fender Set must be test fitted to the actual S15 Silvia before painting. At the front, hood gaps, door-side alignment, bumper transitions, side-step relationships, turn-signal positioning, steering clearance, and wheel clearance should be checked. At the rear, quarter-panel positioning, door press-line alignment, bumper and side-step transitions, fuel-filler area, wheel clearance, suspension travel, and left-to-right symmetry should be confirmed. 326POWER requires temporary fitting and vehicle-specific alignment before painting and notes that elongated-hole processing or similar gradual adjustment may be necessary if mounting positions do not align correctly.

Aero Product Notes

The fenders are supplied unpainted in a white gel coat finish, and installation and painting are not included. The wheel-arch areas use reinforced FRP construction, and any intended arch cutting or raising should be completed during the preparation stage. All panels should be inspected, test fitted, aligned, adjusted, and fully prepared before the final paint finish is applied.

Important Notes

This is an authentic 326POWER Japan Gachabari Medium 2 package developed for the Nissan S15 Silvia. The set combines approximately 45 mm-wide factory-replacement front fenders with approximately 45 mm-wide cover-type rear fenders. The front has no preset arch raise and features a very deep duct with a lowered turn-signal position, while the rear wheel arches are approximately 5 mm higher than stock and follow the press line extending from the doors. Both front and rear arch areas are approximately 30 mm thick and use additional FRP reinforcement to allow further arch adjustment where required. The rear fender reuses the factory fuel filler cap, with an extension stay for the catch included. The product is supplied unpainted in white gel coat and requires test fitting, alignment, preparation, and painting before final installation. Other aero parts, wheels, suspension components, and accessories shown on demo vehicles are separate unless specifically stated otherwise. 326POWER states that the product was developed for show and event use and does not guarantee vehicle-inspection compatibility or assume responsibility for damage resulting from public-road use.
