Best Drum To Disc Brake Conversion Kit for Minis, Cars, and Trucks

#1 · Best Overall

1. Feralmoto Drum to Disc Kit

Best for: Broad-fit mini-bike upgrade.

Why it ranks #1: Names several Coleman, Baja, and Axis mini bikes and specifies a 63mm caliper, 160mm rotor, and weld-on plus bolt-on installation.

A 63mm caliper and 160mm rotor anchor this weld-on and bolt-on conversion for a broad list of mini bikes. Feralmoto names Coleman CT200U and CT200U-EX, BT200X, Axis M200, Baja Massimo MB200, and other Baja models, giving buyers specific applications to check against their machine.

The hybrid mounting approach pairs a weld-on adapter plate with bolt-on components, so the wheel-side adapter requires welding while the remaining supplied components use bolts. The listing says no tire change is needed, which can preserve the current tire during the conversion. Its 63mm caliper and 160mm rotor identify the brake hardware, while the compatibility list spans Coleman, Axis, and several Baja models. Check the listed model names before starting installation.

Skip it if you cannot arrange welding; the GELUOXI Ford kit specifies installation without welding or fabrication.

This is for mini-bike owners whose model appears on Feralmoto’s compatibility list and who want to keep the tire in place. Its weld-on adapter makes access to welding capability a key installation consideration.

#2 · No-Wheel-Change Fit

2. JMCHstore Mini Bike Kit

• Weight: 2.29 lb

Best for: Weld-on mini bike conversion.

Why it ranks #2: Converts an existing mini-bike drum wheel without replacing the wheel or tire; the adapter welds to the original drum hub.

The weld-on adapter plate lets you convert an existing drum-brake wheel to a disc setup without replacing the wheel or tire. JMCHstore lists compatibility with several mini bikes, including Coleman CT200U-EX, CT200U, BT200X, and Massimo MB200, making retained-wheel conversion the central appeal.

Because the plate welds directly onto the original drum hub, the conversion can retain the existing wheel and tire, and the listing says tire removal is not required. That can simplify the wheel-side workflow compared with a conversion that requires changing the tire. Welding is required, and professional welding is strongly recommended, so installation calls for suitable fabrication skills or a qualified welder. The stated fit list includes several mini-bike models, but explicitly excludes the Baja DB30.

Skip it if you need a bolt-on installation without welding; the Feralmoto kit also uses a weld-on adapter plate.

This suits a mini-bike owner who wants a disc conversion while keeping the existing wheel and tire. The key boundary is installation: welding is required, and the Baja DB30 is expressly excluded.

#3 · Vented Rotor Setup

3. Speedway Weld-On Rear Kit

• Compatible with Vehicle Type: Car, Truck, Van
• Weight: 44 lb

Best for: Weld-on rear axle conversion.

Why it ranks #3: A rear weld-on kit with 11.75-inch vented rotors, GM Metric calipers, pads, hats, and caliper brackets for car, truck, or van builds.

Its 11.75-inch vented rotors and compact GM Metric calipers make this Speedway Motors kit a specified rear-disc option for car, truck, or van projects. The kit is weld-on, and its 1.59-inch backspace is an important mounting dimension for buyers planning the installation.

The 11.75-inch rotors are vented and .81 inches thick, a combination the listing associates with cool operation and fade-free braking performance. GM Metric calipers use 2.38-inch pistons, providing substantial piston size in a compact caliper. Included components cover calipers, rotors, pads, hats, slide bolts, and brackets, so the kit supplies major brake hardware together. Its weld-on format means installation requires fabrication rather than a wholly bolt-on process.

Skip it if you need to avoid welding; the Speedway Motors 91031919 is identified as a bolt-on GM 10- and 12-bolt kit.

This kit suits a fabricator upgrading rear brakes on a car, truck, or van who can work with its weld-on mounting and 1.59-inch backspace. Review those installation dimensions before choosing it for an axle project.

#4 · GM Axle Match

4. Speedmaster GM 10/12-Bolt Kit

• Weight: 79.2 lb

Best for: GM 10- and 12-bolt rear conversion.

Why it ranks #4: Specifically identifies GM 10- and 12-bolt rear axles and includes brake lines, with a stated racing-only, not-for-street-use restriction.

A slotted, vented rear rotor and mechanical parking-brake provision distinguish Speedmaster’s GM 10- and 12-bolt conversion kit. The supplied application information identifies it as a rear disc-brake kit, but its legal notice limits use to racing applications and says it is not for street use.

The slotted, vented rear rotors pair with steel calipers and a mechanical parking-brake provision, giving the kit specified hardware for a rear conversion with parking-brake capability. Brake lines are included, while the master cylinder is not, which matters when planning the rest of the hydraulic system. The listing identifies GM 10- and 12-bolt applications, but the racing-only legal disclaimer is decisive: this kit is explicitly not for street use.

Skip it if you need a street-legal setup; the Speedway Motors 91031919 is listed as a bolt-on GM 10- and 12-bolt conversion.

This fits a builder seeking a specified GM 10- or 12-bolt rear conversion with a mechanical parking-brake provision for racing use. Do not select it for street driving; the listing explicitly rules that out.

#5

5. Speedway GM Bolt-On Kit

• Compatible with Vehicle Type: Car, Truck, Van
• Weight: 52 lb

Best for: Bolt-on GM axle conversion.

Why it ranks #5: A bolt-on rear conversion specifically listed for GM 10- and 12-bolt axles, making it a relevant alternative to the weld-on rear kit.

The bolt-on mounting and dual-pattern description set this rear disc conversion apart for GM 10- and 12-bolt applications. Speedway Motors identifies the kit for cars, trucks, and vans, giving builders a named axle family and a non-weld-on installation format to consider.

For a project based on a GM 10- or 12-bolt rear, the title’s bolt-on designation points to mounting without choosing a weld-on kit. The dual-pattern description is a useful application detail for planning the conversion, while the supplied listing does not specify rotor dimensions, caliper type, or individual included brake components. Treat the named axle family and bolt-on format as the supported selection facts, and account for those limits when comparing hardware needs.

Skip it if you need listed rotor and caliper specifications; the Speedway Motors 91031932 provides rotor dimensions and caliper details.

This is for a builder seeking a bolt-on, dual-pattern rear conversion for a GM 10- or 12-bolt project. The available listing is brief, so buyers needing component-by-component specifications should weigh that information boundary.

#6 · No-Weld Installation

6. GPS Manual Conversion Kit

• Compatible with Vehicle Type: Car
• Weight: 60 lb

Best for: Manual front disc conversion.

Why it ranks #6: Designed to mount factory-style four-piston discs on original drum spindles; the listing says it requires no cutting, drilling, or welding.

A direct bolt-on setup mounts factory-style four-piston disc brakes to original drum-brake spindles, with no cutting, drilling, or welding required. This LEED Brakes manual conversion kit also names a cast-iron master cylinder and adjustable proportioning valve, distinguishing its manual configuration.

Using the original drum-brake spindles as the mounting point lets the kit add factory-style four-piston disc brakes without cutting, drilling, or welding, according to the listing. The direct bolt-on approach can avoid fabrication steps during installation. A cast-iron master cylinder and adjustable proportioning valve are specified, giving buyers two named hydraulic components to consider when planning the conversion. This is a manual kit, so choose it when that configuration matches the vehicle’s braking setup.

Skip it if you need a power-brake conversion; the GPS Automotive FC1002-FBB2 is explicitly described as a power kit.

This suits a car owner converting original drum-spindle brakes who wants a manual setup and bolt-on installation. Its manual configuration is the boundary to consider when matching the kit to the vehicle’s braking system.

#7

7. GPS Power Conversion Kit

• Compatible with Vehicle Type: Car
• Weight: 60 lb

Best for: Power disc conversion setup.

Why it ranks #7: A car-oriented power conversion kit that mounts single-piston disc brakes to the vehicle's control arms; the listing does not name specific models.

A 9-inch chrome booster identifies this GPS Automotive power conversion kit for buyers moving from drum brakes to discs. The listing says it mounts single-piston disc brakes to the vehicle’s control arms and specifies a disc/drum side-mount master-cylinder configuration.

The power-kit designation and 9-inch chrome booster distinguish this setup from a manual conversion, while its stated single-piston discs mount to the vehicle’s control arms. The disc/drum side-mount master-cylinder description provides another configuration detail for planning the conversion. The listing describes the components as new, precision-machined products, but does not supply a vehicle model range here. Match the stated control-arm mounting and power configuration to the intended vehicle before selecting the kit.

Skip it if you want a manual setup; the GPS Automotive LEED Brakes FC0001-405 is a manual conversion kit.

This is for a car builder seeking a power conversion with control-arm-mounted single-piston discs and a 9-inch booster. The supplied listing does not name vehicle models, so application matching remains an important boundary.

#8

8. GELUOXI Ford 8/9-Inch Kit

• Compatible with Vehicle Type: Car

Best for: Ford 8- and 9-inch rear kit.

Why it ranks #8: Targets Ford 8- and 9-inch small-bearing rear axles, includes parking-brake cables, and requires 14-inch disc wheels or 15-inch-plus rims.

A no-welding, no-fabrication installation distinguishes this GELUOXI rear disc conversion for Ford 8-inch and 9-inch small-bearing applications. It includes parking-brake cables and mounting hardware, while the listing sets a wheel constraint: 14-inch disc-brake wheels or rims of 15 inches or larger.

The Ford 8-inch and 9-inch small-bearing application identifies the axle family, while included parking-brake cables support a conversion that retains parking-brake provisions. The kit requires axle removal, but its installation notes say no welding or fabrication is needed, clarifying the work involved. Three kinds of shims adjust brake spacing, and three flange types correspond to rear-axle flange selection. Wheel clearance is also specified: use 14-inch disc-brake wheels or rims at least 15 inches.

Skip it if you cannot remove the axles; the Feralmoto mini-bike kit avoids this Ford rear-axle installation requirement.

This suits a Ford 8- or 9-inch small-bearing axle project where parking-brake cables and a no-welding installation matter. Plan for axle removal and verify that the stated wheel-size requirements suit the vehicle.

#9

9. D-ETEGNIK C10 Kit

• Compatible with Vehicle Type: Car

Best for: Classic C10 six-lug upgrade.

Why it ranks #9: Lists 1963–1970 Chevy C10 fitment and 6-lug compatibility, with rotors, calipers, brackets, hoses, and hardware described as included.

Compatibility with 1963–1970 Chevy C10 trucks and six-lug wheels defines this rear disc conversion kit. Its listed package includes rotors, calipers, brackets, brake hoses, and necessary hardware, giving C10 and specified related-vehicle owners a clearly described collection of conversion components.

The year-specific C10 application and six-lug wheel compatibility narrow the intended fit, helping owners assess whether the kit matches their truck configuration. Included rotors, calipers, brackets, brake hoses, and hardware cover the major listed rear-conversion components in one package. The additional fitment information also names 1963–1970 Chevy Suburban and 2WD Blazer applications. Since the listing is specific about vehicles and lug pattern, check both against the project before planning installation.

Skip it if you have a Ford 8- or 9-inch rear axle; the GELUOXI Ford kit names those axle applications.

This suits owners converting a listed 1963–1970 C10, Suburban, or 2WD Blazer with six-lug wheels. Its narrow vehicle-year and wheel-pattern application is the key fit boundary for other projects.

#10

10. EMPI VW Rear Kit

• Compatible with Vehicle Type: Car
• Weight: 0.27 g

Best for: VW IRS emergency-brake conversion.

Why it ranks #10: A focused VW I.R.S. and dune-buggy option with a 4-on-130mm pattern and emergency-brake provision, but it requires 15-inch wheels.

An emergency-brake provision and 4-on-130mm VW bolt pattern define this EMPI rear disc kit for compatible dune buggies. Its listing calls for 15-inch wheels and identifies standard brackets, giving buyers a clear wheel-size constraint alongside the conversion’s parking-brake-oriented use case.

The emergency-brake provision makes this kit relevant to VW IRS conversions where retaining emergency-brake functionality is required, and the listing also describes it for street, off-road, and play cars. Its 4-on-130mm bolt pattern and 14mm threads provide specific wheel-hardware details for application planning. Standard brackets are stated, while 15-inch wheels are required. Those requirements make wheel pattern and available wheel diameter essential checks before choosing this conversion.

Skip it if you use wheels smaller than 15 inches; the D-ETEGNIK C10 kit specifies six-lug compatibility instead.

This suits a VW IRS dune buggy or compatible street, off-road, or play car needing emergency-brake provisions. The 4-on-130mm pattern and required 15-inch wheels are key fit boundaries.
