Overview

The Aggressive Rear Diffuser combines function, form and science on the VA WRX and STI. The more pronounced strake profile gives a sharper, more motorsport-derived rear end than the non-aggressive variant.

State-of-the-art analysis software was used during R&D to extract more performance from the available build volume, increasing downforce and reducing drag on the VA chassis. In-house scan data gives a near-OEM fit and finish.
