Caliper FSLI 1.62in Bore 1.10in Rotor

The Wilwood Caliper FSLI 1.62in Bore 1.10in Rotor is a high-performance four-piston brake caliper engineered for demanding tactical and motorsport applications where consistent stopping power and thermal management are non-negotiable. Built for platforms requiring precision braking under extreme conditions, this Superlite aluminum caliper delivers the responsiveness and reliability demanded by law enforcement and military operators who depend on their vehicles for critical missions. The gray anodized finish provides corrosion resistance while maintaining a professional appearance across diverse operational environments.

Featuring a 1.62-inch bore diameter and optimized for 1.10-inch thick rotors, this caliper utilizes four independent pistons to distribute clamping force evenly across the rotor surface, reducing pad wear and heat buildup during sustained braking cycles. The Superlite construction—a proprietary Wilwood aluminum design—minimizes unsprung weight without sacrificing structural integrity, which is critical for maintaining vehicle dynamics and response time. The 3.500-inch lug mount accommodates standard high-performance rotor configurations, and the 13.06-inch rotor outer diameter ensures adequate friction surface for both street and track-level performance. At 5.2 lbs per caliper, this design represents the balance between durability and weight optimization that professionals require.

This caliper is ideal for law enforcement tactical vehicles, military transport platforms, and high-performance duty trucks where brake fade and extended stopping distances are operational liabilities. Installation requires compatibility with 1.10-inch rotor applications and 3.500-inch lug-pattern mounting surfaces; verify fitment against your specific vehicle platform before purchase. Each caliper is sold individually, allowing builders and fleet operators to configure brake systems with precision matched to their exact requirements and operational duty cycles.
