Why this part
Cheap rebuild kits use standard EPDM or low-grade silicone that hardens and weeps fluid after a few hard sessions. Frenkit's peroxide-vulcanised compound is engineered specifically for high-load brake environments, maintaining its mechanical properties long after budget seals have given up. For Brembo-equipped STi and Evo owners who actually use the brakes, the price difference is negligible against the cost of a caliper rebuild gone wrong.
