Wilwood FSLI4 Front Hat Kit 13.00in Red 2003-05 Scion xA xB

Wilwood FSLI4 Front Hat Kit 13.00in provides a high-capacity braking solution for 2003–05 Scion xA and xB, delivering increased pad capacity for improved thermal handling and consistent pedal feel under repeated heavy use.

This kit pairs the forged Superlite four-piston caliper with oversized 13.00in rotors to translate track-proven stopping power into a dedicated street and light-competition application.

• Forged Superlite four-piston caliper — Forging yields a high-strength, low-deflection caliper body, which maintains consistent piston alignment and pad engagement for stable braking performance.
• Big pad capacity — Larger pads increase thermal mass and contact area, reducing fade during repeated deceleration and extending pad life under demanding use.
• Oversized 13.00in rotors — Greater rotor diameter improves heat dissipation and mechanical leverage at the tire contact patch, resulting in shorter stopping distances and more consistent deceleration.
• Hat-mounted rotor configuration — Lug-mounted hat design adapts to vehicle hub mounting while isolating rotor thermal growth from the hub, preserving wheel bearing and hub integrity under load.
• Performance-oriented application — Built from competition-derived components, the assembly emphasizes reliable modulation and repeatable performance suitable for spirited driving or track days.
• Finish and fit — Red caliper finish provides corrosion resistance and a visual upgrade while matching the specified application for Scion xA/xB front installation.

Each feature in this kit is specified to improve functional braking performance and durability rather than appearance alone. The combination of forged calipers, increased pad area, and larger rotors targets improved thermal management, reduced fade, and precise pedal response.
