Details & specs

Overview

Three lugs is cute. Four lugs opens the whole catalog. This staggered 4-piece set converts the Smart Fortwo 450/451 from its factory 3x112 bolt pattern to 4x156, so you can run real off-road wheels and tires.

Why it's worth it

  • Converts 3x112 to 4x156 for a much wider range of aftermarket wheels
  • Staggered sizing, 2" front and 2.25" rear, keeps the Fortwo's factory-style staggered stance
  • One-piece construction for strength and durability
  • Hubcentric vehicle-side fit centers each adapter on the hub to reduce vibration
  • Wider stance and a more aggressive look on lifted and street builds

Fitment

Fits Smart Fortwo 450 and 451 models, 2006–2015. For the 2016+ Smart Fortwo 453, see our 4x100 to 4x156 adapter kit.

What's in the box

  • (2) front wheel adapters, 2"
  • (2) rear wheel adapters, 2.25"
  • Silver conical seat hex lug nuts

Install

The adapters bolt to the factory 3x112 hubs. Your 4x156 wheels then mount to the adapters using the included lug nuts.

Looks Better Than Bare Aluminum

I like that they aren't bright silver. The darker finish blends into the hub area much better.

I appreciate that the adapters are finished in black instead of raw aluminum. Through the wheel spokes they look much more subtle.
