ISR Performance 5mm Wheel Spacer - 4/5x114.3 Bolt Pattern

Our 5mm wheel spacer in 4x114.3 / 5x114.3 bolt pattern. CNC-machined billet aluminum, sold individually. The thinnest option in our line, and the only one that doesn't require extended studs.

What It Does

Pushes the wheel outboard by 5mm. This is the size for fine-tuning fitment, dialing in that last little bit of poke, or clearing a minor brake interference issue. Because the spacer is only 5mm thick, your factory wheel studs still have enough length to safely clamp the wheel without needing extended studs.

Fitment

4x114.3 and 5x114.3 bolt pattern, 66.1mm center bore. No extended studs required at this thickness. No hub-centric lip on this size; for a hub-centric lip, the 20mm size (IS-451143-20) is the one to look at.
