Description
If you’re upgrading your mid-size GM’s braking system for street or track duty, the Wilwood D154 delivers the stopping power and reliability you need without the guesswork. Dual 1.62-inch stainless steel pistons provide consistent, repeatable braking force across a wide range of conditions, while the lightweight aluminum construction helps you shed unsprung weight. The black anodized finish resists corrosion, and the bolt-on design means you’ll be ready to stop harder in an afternoon, not a weekend.
