RS-652 – The Extreme Hybrid Formula | BARBARO
RS-652
The Extreme Hybrid Formula
Engineered for Endurance & Aggressive Sprinting on Both Carbon-Ceramic and Steel Rotors. Designed specifically for TCR, GT and touring car racing categories — a low-metallic formulation incorporating steel fiber, aramid, graphite carbon, and silicon carbide for unparalleled thermal stability and consistent friction.

Unique Features
Transfer Film Technology
Deposits a 1–3 micron protective transfer layer on the disc surface. Continuously self-renews — protecting the disc while maintaining constant friction. BARBARO’s unique technology.
Powerful Initial Bite
Expansive yet controllable initial torque curve eliminates the cold and hot bite differential that plagued earlier compounds.
Disc-Friendly
Significantly reduces disc attack compared to competing friction materials. Extends disc service life during sprint and endurance races.
46.1% More Pedal Range
Lock threshold raised from 65 bpa (RS-635) to 95 bpa — superior pedal feel and control during trail braking and threshold braking.
Dual Disc Compatible
Validated on both cast iron and carbon ceramic discs. On C/C discs, friction coefficient increases with temperature rise — a unique safety advantage.
Low Wear at High Temps
Uniform and stable material consumption throughout entire service life. No “hard shell / soft core” wear pattern common in competing products.
Composite Material
Steel Fiber
Structural strength & thermal capacity
Aramid
High-temp structural reinforcement
Graphite Carbon
Lubricating layer & heat dissipation
Silicon Carbide
Wear resistance & bite force
Thermal Management
🔧 Steel Disc (Cast Iron)
828°C
690°C
−19.2%
After initial high-temperature carbonization, the second thermal run shows stable friction state with lower peak temperatures.
🏎️ Carbon Ceramic Disc
937°C
817°C
−14.6%
Friction coefficient rises as carbon-ceramic temperature climbs — providing ramp-up stopping power exactly when needed most.
Steel Rotor Friction Benchmarking
Against the two most respected endurance formulas globally — PAGID RSL1 and Endless MA45B.
−8.7% better wear than MA45B
Pressure Sensitivity & Lock-Up Control
Lynk & Co Teamwork Motorsport test data shows RS-635 locks at just 65 bpa. RS-652 raises this to 95 bpa.
RS-635
More Pedal Range
