Wilwood 03-05 Dodge Neon SRT-4 Forged Dynapro 6 Big Brake Front Brake Kit 12.19 - Red

Six-Piston Big Brake Upgrade for 2003-2005 Dodge Neon SRT-4 with 12.19-Inch Two-Piece Rotors

The Wilwood WIL140-16827-DR is a Forged Dynapro 6 front big brake kit designed specifically for the 2003-2005 Dodge Neon SRT-4. It replaces the factory brake system with six-piston forged billet aluminum calipers and 12.19-inch two-piece rotors for dramatically improved stopping power, brake fade resistance, and pedal feel under aggressive street and track use. The red powder-coated calipers add a bold visual element while the electrostatic coating provides long-term corrosion protection. The kit is a direct bolt-on using the factory knuckle and hub with included custom brackets and stainless steel braided brake lines. It requires a minimum 17-inch wheel with at least 7-inch width for proper caliper and rotor clearance.

Key Features

• Six 1.62-inch forged billet aluminum caliper pistons deliver 74.5 square inches of total pad contact area
• 12.19-inch two-piece rotors with aluminum hats reduce unsprung rotational mass by approximately 5 lbs per corner
• 7420 compound pads provide 25 cubic inches of total pad volume for extended pad life
• Red powder-coat finish resists road salt corrosion and withstands sustained track temperatures
• Direct bolt-on to OEM knuckle and hub using included custom brackets and hardware
• Stainless steel braided brake lines included for improved pedal feel and line longevity
• Requires minimum 17x7 inch wheels for proper clearance

Every kit is a complete system designed to install correctly the first time with no modifications to existing mounting points.

Frequently Asked Questions

The Wilwood WIL140-16827-DR is a Forged Dynapro 6 front big brake kit for 2003-2005 Dodge Neon SRT-4. It includes six-piston red powder-coated calipers, 12.19-inch two-piece rotors, 7420 compound pads, custom brackets, stainless braided lines, and all hardware for a direct bolt-on upgrade to the factory front brake system.

Yes. The WIL140-16827-DR uses custom Wilwood-engineered brackets that bolt directly to the OEM knuckle without cutting or welding. The kit is designed to be a complete bolt-on upgrade for the 2003-2005 Dodge Neon SRT-4 front axle.

This kit requires a minimum 17-inch wheel with at least 7-inch width for adequate caliper and rotor clearance. Confirm your wheel offset and spoke clearance using Wilwood's wheel fitment guide before ordering if you are running aftermarket wheels with deep dish or unusual spoke geometry.

Wilwood recommends EXP 600 Plus or Hi-Temp 570 brake fluid for track use with this kit. For street use, a high-quality DOT 4 or DOT 5.1 glycol-based fluid is appropriate. Never use DOT 5 silicone fluid in this system.

Two-piece rotors replace the iron hat section with a lightweight aluminum hat, cutting approximately 5 lbs of rotational unsprung mass per corner compared to a one-piece iron rotor of the same diameter. Less unsprung rotating mass improves wheel response over bumps and reduces the gyroscopic inertia the suspension must overcome during cornering.

In most cases, no. The WIL140-16827-DR is designed to work with the factory master cylinder and proportioning valve on the SRT-4. If you have made significant rear brake modifications, you may need to adjust rear brake bias to maintain a balanced system.

Perform 8 to 10 progressive brake applications from approximately 60 mph to 15 mph, allowing 30 to 60 seconds of cooling between each application. Avoid coming to a complete stop until the rotors have cooled. This deposits an even layer of friction material on the rotor surface and maximizes initial pad bite and longevity.

Yes. The Forged Dynapro 6 with 7420 compound pads is well suited to autocross and HPDE use. The 25 cubic inch total pad volume provides extended life through repeated high-temperature events, and the two-piece rotor design dissipates heat faster than a one-piece iron rotor.

Installation Instructions

1. Safely lift and support the front of the vehicle and remove the front wheels.
2. Remove the factory caliper, rotor, and any associated brackets. Inspect the hub bearing for play or roughness before proceeding.
3. Install the Wilwood caliper bracket onto the OEM knuckle using the included hardware. Torque to specification.
4. Install the new two-piece rotor assembly onto the hub and secure with the factory wheel studs or included hardware.
5. Load the 7420 pads into the caliper and mount the caliper onto the bracket over the rotor. Torque caliper bolts to specification.
6. Install the stainless steel braided brake lines, connecting to both the caliper inlet and the factory hard line junction. Use new sealing washers at all banjo fittings. Torque to specification.
7. Bleed the system completely starting from the farthest caliper from the master cylinder. Verify a firm pedal with no travel before driving.
8. Reinstall wheels and torque lug nuts to factory specification.
9. Perform the 7420 pad bed-in procedure before hard braking use.
