Awesomatix A12 Rear Axle Shim (4) AW-A12-SH12R0.5

Rear end setup on your Awesomatix A12 can be the difference between a car that hooks up cleanly out of corners and one that feels loose or unpredictable. These 0.5mm rear axle shims give you the precision to fine tune your drivetrain geometry and get the traction you need. When you're working on corner exit grip or trying to manage how the rear end responds under power, small adjustments to your rear axle position can make a noticeable difference in how the car puts power down.

You get four shims in this pack, so you have options for testing different configurations or keeping spares ready when you need them. The 0.5mm thickness lets you make incremental changes without drastically altering your baseline setup. If you're dealing with issues like wheel hop, inconsistent traction, or a rear end that feels too planted or too free, adjusting your rear axle spacing with these shims is one of those setup tweaks that can help you find the sweet spot.

The quality matches what you expect from Awesomatix parts. Each shim is machined to maintain consistent thickness, so you're not adding play or misalignment into your drivetrain. They fit cleanly on the axle and sit flush where they need to, doing their job without creating new problems in your rear assembly.

For competitive A12 drivers, having a range of shim thicknesses available means you can adapt to different track conditions and surface types. Whether you're chasing more forward bite on a high grip carpet or trying to smooth out the power delivery on a slick surface, these 0.5mm rear axle shims are a practical addition to your setup toolkit.
