About RS-635
RS-635 is BARBARO’s racing formula for heavier vehicles and endurance racing. It delivers stronger initial bite and wider control range compared to RS-620, making it the go-to choice for high-energy-load applications.
CEC China Endurance Championship (Tianfu Circuit) — Real Race Data:
In head-to-head competition, RS-635 completed 200 minutes of endurance with only 2.335 mm of wear, while PAGID RST3 lasted 120 minutes with 2.59 mm of wear. RS-635 costs only 28% of PAGID’s price — dominating on value and performance.
Benchmark Comparison
vs PAGID RST3
RS-635: 200 min endurance, 2.335mm wear — PAGID RST3: 120 min, 2.59mm wear. RS-635 costs only 28% of PAGID’s price.
vs RS-620
RS-635 offers stronger initial bite (μ 0.47 vs 0.45), wider control range (0.45–0.90 vs 0.45–0.85), and is optimized for heavier vehicles.
Key Features
💪
Stronger Initial Bite
