Wilwood Street Performance FNSL6R BB Front Brake Kits (Hub), Drilled for 70-78 Camaro

The Wilwood FNSL6R Front Brake Kit (Part #140-10486-D) is made for 1970–1978 Chevrolet Camaro models with disc spindles, designed for drivers who want improved braking performance and durability for both street and track use. This system features billet-forged six-piston callipers, which deliver increased and even clamping force for strong, consistent stopping. Large 14” vented rotors help resist brake fade by shedding heat efficiently during repeated or high-speed stops. With forged aluminum callipers and ventilated rotors, the kit keeps weight low without compromising strength. The supplied brake pads are matched to the system, promoting reliable performance and predictable braking. All included hardware is precision-machined for accurate fitment and long-term service.

INSTALLATION OVERVIEW

Installation involves removing the original brake components and modifying the steering arm and spindle by drilling, tapping, and removing material to accept the new calliper brackets. Most installers will want to have these modifications done at a machine shop. The new hubs, bearings, seals, and brackets are assembled following specific instructions and torque settings. The calliper must be shimmed and aligned for proper pad-to-rotor fit. Brake flex lines are not included and require compatible stainless braided lines and fittings to connect with the calliper’s inlet. The brake system needs to be thoroughly bled, and the pads and rotors must be properly bedded for reliable performance. This install is best handled by experienced brake technicians or shops.
