Awesomatix A12 X ST1238 Rear Spring Seat AW-A12-ST1238

The rear spring seat on your Awesomatix A12 plays a bigger role than you might think. This aluminum component sits between your rear shock spring and the shock body, and getting the right setup here can make a real difference in how your car handles through corners and over bumps.

What makes the ST1238 rear spring seat worth attention is how it affects your suspension geometry. The height and angle of this piece changes where your spring sits in relation to the shock shaft, which influences how progressively your rear suspension compresses. When you're dialing in your A12 for a specific track surface or trying to find that sweet spot between mechanical grip and stability, swapping spring seats is one of the adjustments that experienced racers reach for.

This part is machined from quality aluminum, so it holds up to the constant compression cycles that come with racing without deforming or wearing out prematurely. The finish is clean, the tolerances are tight, and it installs exactly where it should on the A12 rear shock assembly. No surprises, no fitment issues.

If you're building up a new A12, refreshing worn suspension components, or experimenting with different rear end setups to improve your car's balance, having the right spring seat on hand matters. It's one of those parts that doesn't get much attention until you need it, but when you do, you want the correct one ready to go.
