The Wilwood Forged Narrow Superlite 6R is a front big brake kit built around a six-piston forged aluminum caliper in red powder coat, mounted radially. Part No. 140-11978-DR pairs that caliper with a 12.88-inch drilled and slotted two-piece rotor on aluminum hats, so it replaces the factory front brakes on the 2006-and-newer Honda Civic as a bolt-on package.
Compared with stock hardware, the larger rotor and six-piston clamping force give the pedal more stopping capacity under repeated hard use. The manufacturer positions the kit for both street and track driving, and its 1.38-inch piston bore sets the caliper apart from smaller single-caliper upgrades. If you are weighing it against cheaper kits, this one is built for heavier braking loads, such as autocross, track days, and aggressive canyon driving, rather than only a cosmetic upgrade.
Plan for 17-inch or larger wheels, since the manufacturer specifies that minimum. The kit is designed to work with the OE master cylinder output and ABS where equipped, which keeps the hydraulic side close to stock. Owners searching for a 06-15 Civic big brake kit, red six-piston front calipers, or a 12.88 drilled rotor upgrade should confirm model-year coverage before ordering, because published CR-Z year ranges vary.
The manufacturer specifies 17-inch or larger wheels for the Forged Narrow Superlite 6R kits, so check clearance against your current wheel and tire package before installation.
The manufacturer states the kit is designed for use with the OE master cylinder output and ABS function where the vehicle is equipped with it.
The manufacturer states the kit is designed for the 06+ Civic and other applications and directs buyers to verify fitment on its website. Published CR-Z year ranges differ, so confirm your exact model year with the manufacturer before ordering.
This kit mounts to the factory disc spindle, so it is a front-end swap rather than a spindle or hub conversion. Confirm wheel clearance with 17-inch or larger wheels before you start, and verify fitment for your exact model year with the manufacturer. Torque specifications, the exact tool list, and bleeding procedure were not confirmed in the manufacturer material reviewed, so follow the manufacturer's install instructions and bleed the system after the swap.
