The Wilwood D154 Front Caliper Kit is a high-performance, bolt-on upgrade designed for mid-size GM vehicles originally equipped with OE cast iron "Metric" calipers. Suitable for vehicles from 1978 through 2002, this kit offers a significant weight reduction and improved durability for street and track applications. Crafted from forged billet aluminum, the calipers feature stainless steel pistons and high-temperature seals that resist rust, bore pitting, and seal failures, ensuring reliable performance over time. This caliper maintains the original mounting points and uses the OE-style brake pads and banjo bolt, making installation straightforward without modifications. With a piston diameter of 1.62 inches, each caliper provides 4.12 square inches of piston area, helping to preserve the original front-to-rear brake bias when paired with the OE master cylinder. The kit includes Wilwood*s hardened slide pins and BP-10 high-friction pads to maximize braking performance and longevity. Compatible with most wheels that clear OE calipers, this caliper enhances braking efficiency while reducing unsprung weight, which benefits handling and responsiveness. For additional customization, Wilwood offers matching rear calipers and stainless steel brake lines, enabling comprehensive braking system upgrades. Whether for street driving, autocross, or track days, the D154 calipers deliver low-maintenance, high-temperature reliability, making them an excellent choice for enthusiasts seeking durability and performance in a direct bolt-on package.
