OfficinaRC Alu Smart Shim 3x9 (8)

The OfficinaRC Alu Smart Shim 3x9 gives you precise control over suspension geometry without the guesswork. Each pack includes 8 aluminum shims machined to a 3x9mm spec, designed to fit cleanly into common suspension pivot and hinge pin setups on 1/10 and 1/12 scale cars. When you are chasing tenths on a technical track layout, having the right shim thickness dialed in makes a real difference in how the car rotates and plants through corners.

Aluminum construction keeps weight low while holding up to the repetitive stress of track use. These are not the kind of shims that deform after a few sessions. They stay true, which means your geometry stays consistent from run to run. Whether you are setting up a touring car for carpet or tuning a pan car for smooth asphalt, these shims give you a reliable baseline to build from.
