Konig Ampliform 5x114.3 18x9.5+25 Gloss Bronze Wheels for the 2018 Subaru WRX STI

The 18x9.5 Ampliform at +25 offset sits between the WRX STI's factory 18x9 and aggressive 18x10 fitment ranges, positioning it as a moderately aggressive setup. This half-inch width increase over stock will require fender rolling and likely benefit from a mild lowering or coilover platform to avoid rubbing; the +25 offset keeps it reasonably tucked without extreme poke. Slight tire stretch is typical at this width—consider a 245 or 255-width tire to balance sidewall support and the stanced appearance shown here.
