Awesomatix A12 Spring Shim (14) A12-SH12S-0.2

The Awesomatix A12 Spring Shim gives you precise control over your suspension setup with fourteen ultra thin 0.2mm shims designed specifically for the A12 touring car platform. These shims let you fine tune spring preload and ride height in tiny increments so you can dial in exactly the handling balance you need for different track conditions. Each shim is precision machined to maintain consistent thickness across the entire surface, which means your suspension geometry stays predictable and repeatable from one corner to the next.

When you're working on setup at the track, having the right thickness options makes the difference between a car that pushes through the sweepers and one that rotates on command. These 0.2mm shims work perfectly under your springs to adjust preload without changing spring rates, giving you another tuning variable to explore when you're chasing lap times. The material holds up under constant compression cycles and won't deform or take a set over time, so your setup stays where you put it throughout a full race day.

Whether you're compensating for worn springs, adjusting corner weights, or experimenting with different ride height configurations, this pack of fourteen shims gives you plenty to work with across all four corners. They install quickly between the spring and shock body, and the uniform thickness means you can stack them predictably if you need more preload. Keep a set in your pit box so you're ready to make suspension adjustments without waiting on parts to show up.
