Konig Ampliform 5x114.3 18x8.5+45 Dark Metallic Graphite Wheels for the 2018 Subaru WRX STI

The 18x8.5 +45 Ampliform sits narrower than the STI's factory 18x9 baseline and well inboard of the aggressive 18x10 stance range, positioning it toward a clean, conservative fitment without requiring fender modifications or suspension tuning on stock ride height. The +45 offset holds the wheel relatively close to the hub, so a lowered setup as shown will create modest poke without aggressive tucking; square-tire fitment is straightforward at this width. Consider a 245–255 tire width to maintain sidewall support and avoid excessive stretch.
