The Truth About Wheel Spacers (And Why We Don’t Use Them)

Walk into any tuning shop and you’ll see them: aluminum discs designed to push a wheel further out to achieve that “flush” look. While wheel spacers are common, they are fundamentally a band-aid solution for a wheel that doesn’t fit the car properly.

The Problem with Spacers

Adding a spacer changes the scrub radius of your suspension, increases the lever arm force on your wheel bearings, and introduces a potential point of failure between the wheel and the hub. For a track-focused or high-performance street car, this is unacceptable.

At RRT Forged, we engineer the offset (ET) directly into the forging profile of the wheel. We measure your exact vehicle’s brake caliper clearance and fender dimensions, and machine the hub pad to the millimeter. The wheel bolts directly to the hub, perfectly flush with the fender, exactly as the suspension engineers intended.
