The Wilwood Iron GM Metric Caliper with a 2.75-inch piston is a high-performance, cast iron brake caliper designed as a direct bolt-on replacement for 1978 and newer GM Metric calipers. Engineered for durability and consistent braking performance, these calipers are ideal for "spec" racing categories and cost-effective disc brake conversions. Constructed from high-quality cast iron, they provide reliable heat resistance and long-lasting performance. The calipers are designed to enhance braking response and fade resistance, making them suitable for both track and street applications. Their robust build ensures durability under demanding conditions, offering a cost-efficient upgrade for performance enthusiasts.
These calipers are compatible with a wide range of GM vehicles from 1978 onward, specifically fitting models utilizing GM Metric calipers. They require the use of hardened Wilwood slide pins, sold separately, with part no. 230-0619, which includes four pins sufficient for two calipers. Installation involves straightforward bolt-on replacement, making them suitable for track days, autocross, or daily driving upgrades. The kit does not include slide pins but is designed to work seamlessly with Wilwood’s high-performance brake systems, providing improved stopping power and modulation for various vehicle setups.
