The Wilwood Forged Narrow Superlite 6R front big brake kit upgrades the Honda Civic and CR-Z with six-piston forged aluminum calipers and 12.88 inch vented rotors. The FNSL6R caliper uses staggered 1.38, 1.12, and 1.12 inch stainless pistons for even pad loading and heat control, and the GT 48 curved-vane rotors are cross-drilled and slotted Spec-37 iron for cooling and clean pad bite. Kits are engineered application specific for compatibility with the OE master cylinder output and ABS.
