Wilwood Mopar 11.75" Front Disc Brake Kit (Stage 2 Plus)

The 11.75” disks aren’t Wilwood they’re factory. No weight savings there, they’re heavier than the 10.95” disks. The calipers are definitely lighter than the stock ones, but since it’s just the calipers and caliper brackets you’re probably talking about 5-6 lbs per side.
