Wilwood 120-11130-RD FSLI Forged Superlite Brake Caliper - 6-Piston Red

The Wilwood FSLI Forged Superlite brake caliper represents the pinnacle of racing caliper technology, engineered for short track, late model, modified, open wheel, road racing, off-road, and rally competition. This advanced caliper combines stress-flow forged construction with proven performance features to deliver superior stopping power with reduced pedal travel.

Stress-Flow Forged Construction:

Each caliper body is stress-flow forged from premium grade aluminum alloy billets, a process that re-aligns the metal's internal grain structure to flow within the contour of the caliper body. This eliminates the stresses and grain interruptions that occur with traditional billet machining, creating the strongest possible aluminum caliper body.

Advanced FSL Body Design:

• Computer-generated solid modeling and stress analysis optimized design
• Closed end bridges with radial transition to piston housings
• Eliminates machined steps and sharp shoulders for increased strength and deflection resistance
• Center bridge bolts replace cotter pins for quick pad access and positive retention
• Superior clamping force with minimal structural deflection

Performance Features:

• Replaceable SRS stainless steel bridge plates eliminate pad gouging and extend caliper life
• Spring-loading action of SRS plates prevents pad rattle and reduces brake squeal
• High-temperature square-faced O-ring seals for positive sealing and controlled piston retraction
• Stainless steel pistons resist corrosion and retard heat transfer from brake pads
• Two-piece bleed screw assemblies for reliable, long-lasting service

Compatibility and Applications:

FSLI calipers are direct replacements for all Wilwood Superlite and similar competitive brand calipers with 3.50" centered mounting tabs. Available in multiple piston sizes (1.75", 1.62", 1.38", 1.25", 1.12") for various rotor widths (.81", 1.10", 1.25"). Uses standard 7420 type bridge bolt brake pads, compatible with the full range of Wilwood PolyMatrix pad compounds.

Includes six-piston design in red anodized finish for maximum braking performance and distinctive appearance.
