The Wilwood DPHA (DynaPro Honda/Acura) front caliper, part 120-12949-BK, is a forged billet aluminum four-piston caliper in black powder coat. It is a direct bolt-on for Honda and Acura models that came from the factory with 262mm front rotors. It mounts to the stock spindle mounts, takes the factory brake hose, and the manufacturer says it keeps ABS function.
Stainless steel pistons are the main reason to step up from stock. The manufacturer says the four pistons load the pads evenly, and the stainless alloy resists corrosion and heat. The forged body is built for high-strength clamping force and firm pedal response. Owners on user forums have reported running this setup on higher-horsepower builds without brake fade, though that is anecdotal. Compared with a cheaper bolt-on caliper, the real payoff is repeatable stopping on track days, durability under heat, and a more consistent pedal. Search terms for this part include DPHA front caliper, Honda Civic Integra 262mm big brake upgrade, forged billet 4-piston caliper, and 120-12949-BK.
The manufacturer states it bolts directly to the stock mounts on factory spindles of Honda and Acura models originally equipped with 262mm rotors. Confirm your exact year and model with the manufacturer before ordering.
The manufacturer states the caliper accepts the OE brake hose. Confirm the banjo fitting details with the manufacturer before ordering hardware.
The manufacturer's Honda and Acura assembly instructions say to inspect the existing OE rotors for proper service condition and replace them with new Wilwood rotors if necessary.
This is a moderate DIY job for someone comfortable with front brake work. Per the manufacturer's Honda and Acura assembly sheet, mount the caliper to the hub bosses with the supplied bolts and washers, coat the bolt threads with red Loctite 271, and torque to 60 ft-lbs. Install the pads with the friction material facing the rotor and secure them with the retainer clip. Keep brake fluid away from the pad and rotor faces. When bleeding, start with the caliper farthest from the master cylinder, bleed the outboard screw first, and use a catch bottle. The manufacturer recommends Wilwood Hi-Temp 570 fluid for best performance. Check wheel clearance before final assembly, and bed the pads following the manufacturer's procedure.
