Product Description

The Wilwood 120-12949-BK Forged DynaPro Honda/Acura (DPHA) brake caliper is a high-performance braking upgrade engineered specifically for Honda and Acura platforms originally equipped with 262mm front rotors. Designed as a direct bolt-on replacement, this caliper mounts directly to the factory spindle and works with the original rotor size and brake hose connection, allowing enthusiasts to upgrade braking performance without extensive modifications. The compact DPHA design also clears many factory 15-inch wheels, making it a popular upgrade for street and track applications.

Constructed from lightweight forged aluminum, the DPHA caliper delivers exceptional strength, rigidity, and heat dissipation. Four stainless steel pistons provide balanced pad loading and improved braking response while resisting corrosion and heat transfer for consistent performance under demanding conditions. Compatible with most OE master cylinders and ABS systems, this caliper maintains factory drivability while significantly improving stopping power, pedal feel, and braking consistency. It is ideal for performance builds, track-day cars, and enthusiasts seeking motorsport-grade braking reliability.
