Kansei Wheels KNP 18x10.5 +12 specs

The wheels are 18-inch in diameter and 10.5 inches wide with a +12 offset.

A +12 offset on a 10.5-inch wide wheel puts the wheel face in a very aggressive position at or past the fender. Lower offset moves the wheel outward; higher offset tucks it in.

245/40R18 tires on 18x10.5 wheels

The tire size is 245/40R18: a 245 mm section width with a 40 aspect ratio on the 18-inch wheel, which gives a stretched fit (the tire is narrower than the wheel, which pulls the sidewall in and helps clear the fender).

The owner chose Federal SS 595. We stock Ironman IRON iMOVE Gen 3 AS 245/40ZR18XL at $101 each in this size, and other 245/40R18 tires through the 245/40R18 tire search.

Suspension, stance and clearance

The drop comes from lowering springs, the simplest way to close the fender gap on a Subaru WRX while keeping the factory shocks.

No rubbing at all, front or rear, no spacers, rolled fenders. Rolling or pulling the fender is what most owners do once the wheel sits this close; it keeps the tire from catching the lip over bumps.

Stance: flush. The wheel face lines up with the fender. Flush fitment on a Subaru WRX comes down to the offset and width above; copy them and you get the same result.
