Konig Ampliform 5x114.3 18x10+20 Gloss Bronze Wheels for the 2018 Subaru WRX STI

The 18×10 +20 Ampliform sits at the outer edge of aggressive fitment for the 2018 STI, matching the platform's stance-oriented sizing while maintaining factory bolt-pattern compatibility. At +20 offset, this wheel will pull noticeably outward compared to factory 18×9 applications, typically requiring fender rolling and may necessitate lowering or coilover setup to clear the chassis without rubbing. Slight tire stretch is viable at this width; 265–275mm rubber will fill the wheel appropriately while preserving sidewall support on the STI's performance suspension.
