Best Side Skirts and Side Aero for the 2022–2026 WRX: 5 Top Picks Compared
For a 2022–2026 WRX, side aero splits into three honest tiers: Subaru's OEM strake kit ($119.95) adds a small fin to the factory skirt, AeroflowDynamics' T-SPEC extensions ($200) run a full blade under the stock skirt, our own JDMuscle Spec STI carbon fibre side skirts ($485) replace the look in carbon, and Subaru's OEM STI side under spoiler kits ($499.99, in black or cherry red) are the factory-engineered full treatment. Every piece below was verified live in our catalog today.
Extension, Strake or Full Skirt?
A strake is a small vertical fin at the rear of the skirt — a detail piece. An extension is a flat blade that bolts beneath the factory skirt and gives the car a lower, wider side profile without replacing anything. A full skirt or under spoiler replaces or comprehensively trims the whole rocker area. None of these is primarily a downforce device at road speeds; they are stance and finishing parts, and they pair with a front lip and rear diffuser to read as one kit — see our VB hood guide and the full sequence in the VB modification guide.
1. Subaru OEM Strake Kit for Side Skirts — $119.95
Subaru OEM [22-26 WRX] Strake Kit for Sideskirts — $119.95. The subtle factory option: Subaru's own strake kit for the 2022–2026 car's side skirts, at the lowest price in this guide. Strakes are the finishing flick that owners add after the bigger pieces — or the only change for owners who like the car exactly as it sits, plus one detail.
2. AeroflowDynamics Side Skirt Extension T-SPEC — $200
AeroflowDynamics [22-26 WRX] Side Skirt Extension T-SPEC — $200. The value full-length blade: AeroflowDynamics' T-SPEC extension, listed across the 2022–2026 range. Extensions like this are the most popular side-aero format on the VB because they transform the side profile for the least money and no removed parts — the factory skirt stays, the blade goes under it.
3. JDMuscle Spec STI OEM Style Carbon Fiber Side Skirts — $485
JDMuscle [22-26 WRX] Spec STI OEM Style Carbon Fiber Side Skirts — $485. Our own carbon fibre skirt in the OEM STI style — the shape Subaru's own design language suggests, executed in carbon. This is the pick for owners building a carbon theme across the car, and it matches the other Tanso carbon pieces in our catalog for this platform.
4. Subaru OEM STI Side Under Spoiler Kit, Black — $499.99
Subaru OEM [22-26 WRX] STI Side Under Spoiler Kit — Black — $499.99. The factory STI under spoiler for the VB, in black: OEM engineering, OEM fitment, and the conservative colourway that works with every body colour. Factory aero is never the cheapest route, and owners buy it precisely because the fit and finish are guaranteed by the people who built the car.
5. Subaru OEM STI Side Under Spoiler Kit, Cherry Red — $499.99
Subaru OEM [22-26 WRX] STI Side Under Spoiler Kit — Cherry Red — $499.99. The same factory STI under spoiler in STI's signature cherry red — the accent colourway that ties into the red details elsewhere on STI-trimmed cars. Choose between picks four and five on colour alone; the part underneath is the same factory piece.
Fit the Set, Not Just the Side
Side aero reads best as part of a matched set — front, side and rear at the same visual weight. Our own chassis part for this car is the JDMuscle [22-26 WRX] Front Member Brace — $119, and the full VB build order is in the modification guide linked above.
