The Wilwood caliper wear plate for DP6 (and DP6A) calipers is a stainless steel alloy plate intended to prevent pad "dig-in" and wear on aluminum caliper bodies. Manufactured for abrasion resistance, this specific wear plate fits the DP6 family and helps preserve caliper surfaces where pads contact the caliper housing, extending service life of the caliper body in heavy-use conditions.
