Speedway Motors 1967–1969 F-Body Kit

This power-assisted four-wheel disc conversion kit is listed for 1967–1969 F-Body applications. It uses an 11-inch rotor diameter and a 5-on-4.75-inch bolt pattern, with a staggered rear arrangement. Those details make it a practical starting point for owners whose vehicle matches the stated application and hardware specifications.
Best for: Owners of a 1967–1969 F-Body who want a power four-wheel disc setup and have verified the bolt pattern and rear configuration. It was selected for its clearly stated fitment range and key dimensions.
Check before buying: The provided features do not identify every trim, axle, or wheel-clearance requirement. Confirm those details for your specific car before ordering.
10 Brakes Premium Mustang Kit

This kit is described for 1967–1969 Ford Mustangs with automatic transmissions and Ford 8-inch or 9-inch rear axles. Its listed features include front and rear 11-inch drilled and slotted rotors, four-piston zinc-plated front calipers, and a bolt-on installation that requires no cutting or welding. Red or black powder coating is listed as an option.
Best for: Mustang owners whose transmission and rear axle match the listed application and who want drilled and slotted rotors. It stands out for its stated axle and transmission criteria and included front-caliper details.
Check before buying: The application is specific to automatic-transmission cars. Avoid assuming it fits a manual-transmission Mustang without confirming with the seller.
Speedway Motors 1965–1968 Impala Kit

Designed for 1965–1968 Impala applications, this power conversion kit is intended to replace a drum-brake setup with four-wheel disc brakes. The listed package includes 11-inch drilled and slotted rotors, red loaded GM calipers, braided stainless-steel hoses, hardware, seals, and bearings. The product information says the conversion does not require a spindle swap.
Best for: Impala owners seeking a kit with several specified installation components included. The no-spindle-swap detail may be useful for buyers comparing conversion scope, but verify that the statement applies to the exact vehicle configuration.
Check before buying: The listed features do not provide a complete breakdown of every compatible trim or axle. Confirm vehicle fitment and wheel clearance before purchase.
10 Brakes 1964–1969 Fairlane Kit

This complete front-and-rear conversion is listed for 1964–1969 Ford Fairlane models. Its features include red powder-coated calipers and cross-drilled and slotted rotors. These details make it an option for Fairlane owners who want a four-wheel conversion with a colored caliper finish as part of the listed specification.
Best for: Fairlane owners whose model year matches the stated range and who prefer the red-caliper appearance. It was selected because it specifies the vehicle application and includes both front and rear disc components.
Check before buying: The provided product details do not list axle, wheel, or trim-level fitment conditions. Confirm those points rather than relying on model year alone.
Force10 1964–1969 Mustang Kit

The Force10 kit is described as a complete front-and-rear disc conversion for 1964–1969 Mustangs. Its listed installation approach is direct bolt-on to original V8 drum-brake spindles, with no cutting, drilling, or welding. The front system features factory-style four-piston calipers.
Best for: Owners of a Mustang matching the stated years and original V8 drum-brake spindle application. It is a useful comparison against the other Mustang kit because its fitment description focuses on spindle type rather than specifying an automatic transmission and rear axle.
Check before buying: The stated spindle application is specific. Confirm your car has the required original V8 drum-brake spindles before choosing this kit.
Buying Guide: How To Choose A Four-Wheel Disc Conversion
Does the kit fit your exact vehicle?
Start with year, make, and model, then check the details that can narrow fitment: transmission, rear axle, spindle type, and brake arrangement. The Mustang kits illustrate why year range alone is not enough. One specifies an automatic transmission and Ford 8-inch or 9-inch rear axle, while the Force10 listing specifies original V8 drum-brake spindles.
What should you compare in the included components?
Review whether the kit includes front and rear components, rotors, calipers, hoses, bearings, seals, and installation hardware. The Impala kit lists several of these parts; other listings provide different levels of detail. Ask for a complete parts list if a component is not identified in the product information.
Do rotor and wheel specifications matter?
Yes. The F-Body kit specifies 11-inch rotors and a 5-on-4.75-inch bolt pattern. Confirm rotor dimensions, bolt pattern, and available wheel clearance against your car. Do not assume that a kit fits your existing wheels solely because the vehicle’s year and model appear in its title.
Should you choose drilled and slotted rotors?
Several listings include drilled and slotted rotors, while the F-Body listing specifies rotor diameter without that detail. Compare the actual kit configuration and intended use rather than selecting by appearance alone. Also check whether caliper color or finish is important to your project.
What installation details should you verify?
Check whether the listing describes a bolt-on installation and whether any spindle changes or other modifications are required. A stated bolt-on design does not replace vehicle-specific fitment checks. For safety-critical brake work, use the installation instructions and have the completed system inspected by a qualified professional.
Frequently Asked Questions
What does a four-wheel disc brake conversion kit do?
It replaces drum brakes at the front and rear with disc brake components, according to the kit’s specified vehicle application and included parts.
Are all four-wheel disc kits universal?
No. These listings are vehicle-specific and may also depend on the transmission, axle, spindle, or bolt pattern.
Can I keep my current wheels?
Do not assume so. Compare the kit’s rotor and bolt-pattern specifications with your wheels and confirm clearance for your exact setup.
Do these kits include everything needed for installation?
Included components vary. Review the product’s parts list and ask the seller about any unlisted items before ordering.
Which Mustang kit should I compare first?
Choose based on fitment: compare the Premium kit if your Mustang has the stated automatic transmission and rear axle, and consider Force10 if it has the specified original V8 drum-brake spindles.
