DMAKER STI-Spec Rear Diffusers / Under Spoilers for Subaru WRX (VB) 2022-2025

Product Description

DMAKER STI-Spec Rear Diffuser / Under Spoiler for Subaru WRX (VB) 2022-2025

The DMAKER STI-Spec Rear Diffuser / Under Spoiler is a premium exterior upgrade developed specifically for the Subaru WRX (VB) 2022–2025. Designed with OEM+ philosophy and STI-inspired styling cues, this rear diffuser enhances the WRX’s rear-end presence while maintaining factory-correct proportions, fitment, and everyday usability.

Shaped to integrate seamlessly with the factory rear bumper, the STI-Spec diffuser adds definition to the lower rear profile, visually widening the vehicle and reinforcing a more planted, performance-oriented stance. The design is intentionally refined, delivering subtle aggression that complements the WRX’s original design language rather than overpowering it.

Manufactured to meet high durability and fitment standards, the rear diffuser follows model-specific contours of the VB chassis for a clean, factory-intentional appearance. The understated finish allows it to pair seamlessly with both stock and modified builds, as well as other STI-Spec aero components.

Engineered for real-world driving conditions, the DMAKER STI-Spec Rear Diffuser balances visual enhancement with practicality. Whether completing a full STI-Spec aero package or refining the rear-end detail of your WRX, this diffuser delivers OEM+ styling confidence with long-term durability and cohesive design integration.

Product Terms & Conditions – Fitment, Returns & Warranty

We strongly recommend conducting a test fit of all products prior to any painting, modification, or installation. This ensures compatibility and fitment, and helps prevent issues that may affect your eligibility for a return or warranty claim.

• Products must be returned in their original, unused, and resalable condition, including all original packaging and accessories.

• Any product that has been installed, painted, modified, or damaged may not be eligible for return or warranty consideration.

• Claims for return or warranty will not be accepted if the item shows signs of tampering or use beyond the test fit stage.

Our policies comply with the Australian Consumer Law (ACL), which provides certain guarantees that cannot be excluded. These include the right to a repair, replacement, or refund if a product is faulty or not as described.

Our team takes great care to achieve the most accurate paint match possible, factoring in the natural differences between plastic and metal surfaces, which can affect paint bonding and finish. While slight shade variations may occur due to these material differences, we proudly deliver a 99% paint match accuracy across all factory shades -with the exception of Ceramic White, which reaches up to 95% accuracy due to its unique pigmentation characteristics.

While we strive to match paint colours as closely as possible, please note the following conditions regarding paint-related claims:

• Paint finish and colour variation are not covered under warranty unless the product is painted in the incorrect colour code compared to the customer’s order or, delivered with significant defects such as peeling, cracking, or flaking within 12 months of purchase

• Slight differences in paint appearance caused by surface material (e.g. plastic vs. metal), lighting conditions or application methods, which are considered normal and not eligible for refund, exchange, or warranty claims.

• Any claims related to paint issues must be submitted within 7 days of receiving the product, along with clear photographs for assessment.

• Warranty does not apply if the item has been installed, altered, repainted, or otherwise modified. This also apply to damages due to misuse, accidents, or improper storage
