Product Description

The Wilwood 140-11978-R is a Forged Narrow Superlite 6R front big brake kit built for the Honda Civic and CR-Z, pairing six-piston calipers finished in red powder coat with a 12.88-inch slotted rotor. The FNSL6R caliper's narrow-body design was engineered specifically to fit within the tighter wheel wells common on compact cars like the Civic, while still delivering the clamping force and stopping power associated with Wilwood's bigger six-piston calipers.

Because this kit is application-specific rather than a universal bolt-on, installation is more straightforward and it remains fully compatible with your Civic or CR-Z's factory master cylinder output and ABS system where equipped. The slotted rotor surface helps with debris clearing and bite, complementing wheel, tire, and suspension upgrades on a show car or dual-purpose street/track build.

Since Wilwood offers several caliper finish and rotor style combinations across this kit family (including a drilled-and-slotted red variant, 140-11978-DR), confirm you're ordering the exact configuration - red calipers with a slotted, non-drilled rotor - that matches this listing.
