TEI Big Brake Caliper Kit S-X One-piece Forged 10 Piston Brake Caliper 400mm/410mm/420mm Disc Front BBK for Porsche Panamera

TEI S-X 10 Piston Brake Kit – The Pinnacle of Braking Innovation for 20-inch+ Wheels

TEI S-X 10 Piston Brake Kit represents the ultimate evolution of performance braking. Designed exclusively for 20-inch and larger wheels, this flagship system combines aerospace-grade materials, titanium vented pistons, and one-piece forged construction to deliver extraordinary stopping power, heat control, and structural strength.

Forged One-Piece Caliper

1. Each S-X caliper is CNC-machined from 6082-T6 aerospace aluminum alloy, achieving exceptional rigidity while maintaining a lightweight structure.
2. Its hollow monoblock design reduces unsprung mass for improved handling and steering response, while reinforcement ribs provide superior stiffness to eliminate flex under high pressure.
3. The titanium alloy vented pistons ensure rapid heat dissipation and fade resistance, even under extreme braking conditions.
4. External dust-proof structure protects the caliper’s internals from debris and high-temperature gases, guaranteeing long-term reliability and smooth piston movement.

These innovations create a caliper that’s not only visually striking but also engineered for consistent, race-proven performance.

Dual Rotor Options

The TEI S-X Brake Kit offers two advanced rotor configurations:

• G3500 High-Carbon Alloy Rotors – Featuring enhanced carbon content for superior heat stability and vibration control, available in slotted, drilled, or slotted-drilled options to balance cooling efficiency and friction performance.

• Carbon Ceramic Rotors (Optional) – Ultra-lightweight, fade-proof, and designed for extreme endurance, these discs provide instant response and consistent braking under the harshest track or street conditions.

Both rotor types are engineered to deliver smooth engagement, optimal heat dispersion, and exceptional resistance to cracking or warping.

High-Performance Ceramic Pads

The auto brake system includes ceramic brake pads with a friction coefficient of 0.38–0.43, ensuring strong initial bite, quiet operation, and low dust output.
These pads maintain stable friction across a wide temperature range, offering the perfect balance of comfort and performance — whether in daily driving or high-speed braking scenarios.

Proven Braking Test

From 100 km/h to 0 km/h, the TEI S-X 10 Piston Brake Kit achieved an average stopping time of just 2.5 s, proving its unmatched consistency, control, and efficiency.
