Forgestar Wheels F14 Gloss Gunmetal 20x9 +40 specs (staggered)

The wheels are 20-inch in diameter and 9 inches wide with a +40 offset up front, and 20-inch by 11 inches at +55 in the rear.

A +40 offset on a 9-inch wide wheel puts the wheel face in a mild push toward the fender. Lower offset moves the wheel outward; higher offset tucks it in. The rear +55 offset on the 11-inch wheel keeps the rear in line with the front.

255/35R20 / 315/35R20 tires on 20x9 wheels

The tire size is 255/35R20 front and 315/35R20 rear: a 255 mm section width with a 35 aspect ratio on the 20-inch wheel, which gives a meaty fit (the tire is wider than the wheel, so the sidewall bulges a little and gives more cushion).

The owner chose Nitto Motivo. We stock Lexani LX-TWENTY 255/35R20 at $117 each in this size, and other 255/35R20 tires through the 255/35R20 tire search.

Suspension, stance and clearance

The drop comes from Eibach Pro-Kit Springs lowering springs, the simplest way to close the fender gap on a Ford Mustang while keeping the factory shocks.

No rubbing at all, front or rear, no spacers, no fender work. That means the setup fits as-is, which is what most owners want to know before they buy.

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