What is the purpose of the staggered piston design in this caliper?

The staggered piston arrangement in the FNSL6R caliper helps to optimize brake pad wear and distribute braking force more evenly across the rotor surface. This leads to more consistent and effective stopping power, especially during hard braking.

What rotor thickness is this caliper designed for?

This Wilwood FNSL6R caliper is specifically designed to work with brake rotors that are 1.25 inches thick. It's important to match the caliper to the correct rotor thickness for proper function and performance.

Does this caliper come with brake pads or lines?

This product listing is for the Wilwood FNSL6R caliper only. Brake pads and brake lines are typically sold separately and should be chosen to be compatible with this caliper and your vehicle's braking system.

Product Details

The FNSL6R caliper from Wilwood features a unique staggered piston arrangement with a 1.62-inch piston paired with two 1.12-inch pistons on one side, and another 1.12-inch piston on the other. This setup is specifically designed to work with rotors that are 1.25 inches thick, allowing for a more balanced and effective braking force distribution. This caliper is a left-hand unit, intended for use on the driver's side of the vehicle.

Wilwood builds these calipers with a focus on performance and durability. The FNSL6R uses a forged aluminum body, which is strong yet lightweight, helping to reduce unsprung weight. This construction contributes to better handling and suspension response. The staggered piston design is a key feature that helps to optimize pad wear and ensure consistent braking performance, especially under demanding conditions. This caliper is a solid choice for those looking to significantly upgrade their vehicle's braking system for track days, spirited driving, or heavy-duty applications.

When installing this caliper, it's important to ensure compatibility with your existing brake system components, including rotor size and brake lines. Refer to the manufacturer's installation instructions for proper fitment and bleeding procedures to achieve optimal performance. This caliper is designed for use with specific rotor thicknesses, so confirm your rotor specifications before purchase.
