🏁 Yperion Titanium Caliper Piston Kit for Subaru STI Upgrade your stock calipers with the same engineering found in top-tier racing systems. While factory aluminum pistons conduct massive amounts of heat and boil your brake fluid, Yperion Titanium pistons deliver ultimate thermal defense and unyielding performance.
⚙️ Engineered to Deliver
🔥 Multi-Stage Heat Treatment
Increases titanium hardness and structural strength for maximum wear resistance. This advanced hardening allows us to machine a complex, ultra-lightweight inner wall profile using Finite Element Analysis (FEA)—shedding weight while keeping stock outer dimensions unchanged.
💎 Three-Layer DLC Coating
Diamond-Like Carbon layer minimizes friction (drag) for smooth piston retraction and razor-sharp pedal response. Applied in a specialized plasma environment, this process bonds the coating perfectly without decompressing or weakening the hardened titanium.
⚡ Optional Crown Grooves
Custom-engineered slots on the piston face reduce the contact surface area against scorching-hot brake pads. Less contact area means significantly less heat transfer into your brake system.
🏆 The Track & Street Advantage
Zero Fluid Boil: Titanium acts as a natural thermal barrier.
Consistent Pedal Feel: No more spongy pedal, even under extreme track abuse.
Zero Corrosion: Built to outlast standard components without seizing.
📦 Flexible Setup Option: Get the ultimate upgrade tailored to your needs—Front and Rear piston kits can be purchased separately or together as a full set. ⚙️ Yperion Titanium — Precision engineering for those who refuse to compromise
