Wilwood Front Hat Kit FSLI4 13in Drilled Red 2003-05 xA xB

Front brake upgrade: The Wilwood FSLI4 Front Hat Kit 13.00in Drilled Red provides the Wilwood forged Superlite four-piston caliper with oversized rotors to deliver increased pad capacity and improved thermal management for consistent, track-proven stopping performance.

This kit pairs Wilwood engineering and competition-derived design to address braking performance and durability in demanding driving conditions while maintaining application-specific fit for 2003–2005 Scion xA and xB models.

• Forged Superlite four-piston caliper — big pad capacity: Larger pad area increases friction surface for stronger initial bite and extended service intervals under repeated deceleration.
• 13.00in drilled rotor — enhanced heat dissipation: Drilled rotor faces aid in venting gases and surface heat, helping preserve consistent lever feel and reduce risk of thermal degradation during hard use.
• Hat-style rotor integration — rigid mounting interface: Hat-mounted rotor architecture centralizes structural loads and maintains rotor runout control for repeatable braking performance.
• High-visibility red finish — corrosion resistance and identification: Factory-applied finish provides a durable surface treatment for component protection while offering visual confirmation of Wilwood hardware.
• Competition-derived construction — proven reliability: Design roots in motorsports reflect a focus on weight control, stiffness, and repeatable performance under track conditions.

Engineered for performance braking upgrades, this Wilwood kit focuses on functional gains—greater pad capacity, improved thermal control, and a robust caliper/rotor interface—without compromising application specificity for the listed Scion models.
