Titanium Caliper Pistons for subaru STI Gold / Black calipers

We aimed to exceed all previous accomplishments. Our pistons are designed with finite element analysis and crafted from the most robust titanium alloy, which undergoes a multi-stage heat treatment to enhance its hardness. This process boosts the material's durability and enables us to manufacture extremely lightweight pistons, as the piston wall can be made exceptionally thin. Nevertheless, to accomplish this, we must precisely machine the interior of the piston wall; all external measurements must remain unchanged. It's not clearly visible in the images that the piston's internal structure is more intricate than your original pistons.

Yperion Titanium aliper piston kit for Subaru Sti is the best solution for original calipers. Stock pistons conduct much more heat due to the high thermal conductivity of aluminum. With our titanium pistons, you can upgrade your original caliper with the same pistons found in top-end racing calipers. We create a highly complex piston inner wall profile, specifically calculated using the finite element method. The piston also features a three-layer DLC coating for minimal wear and friction, which is crucial. Our coating is specifically tuned so that when applied in a plasma environment, we don't decompress the piston, which has a hardened structure (for high hardness and strength).All this combined makes this piston one of the most complex products that we make.
