Brake Noise

Because the optional 4-piston calipers are basically intended for high performance, they have a tendency to squeal.  Most conventional cures are not effective, but Wilwood offers an anti-squeal backup plate that is said to work.  Available directly from Wilwood for under $15, the part number is 300-8460 for all pads that fit the Wilwood and Sierra calipers that ERA offers as an option.
