Forged Drop Spindle Front Disc Brake Kit – EMPI
Included rotors are drilled for both 5x130mm (14×1.5mm) and 5×4.75″ (12mm) threads, with calipers, pads, wheel bearings, and grease seals included. Best for classic VW builds that require multiple bolt patterns without custom machining. This kit is well-suited for owners restoring 5-lug VW setups or upgrading drum brakes on older 5-lug spindles. A potential limitation is the need to ensure wheel compatibility with the dual-drill patterns and the absence of spindles if the kit is listed as “without spindles.”
Who it’s best for: VW enthusiasts seeking a robust, multi-pattern upgrade that preserves classic wheel options while improving stopping power. Choose this if you want a comprehensive package with rotors, calipers, bearings, and seals ready to install.
Bolt-On Front Disc Brake Kit – EMPI
This VW ball joint bolt-on kit uses a 4x130mm lug pattern (14mm threads) and is designed to work with stock-style drum spindles. It is best for classic VW owners who want a simpler upgrade path that aligns with factory geometry. Limitations include compatibility only with stock drum spindle configurations, so it may not fit non-stock spindles without modification.
Who it’s best for: VW owners aiming for a straightforward bolt-on upgrade using existing spindles. Choose this if you want a quick setup with clear wheel compatibility expectations.
CWLQGGJLJH Disc Brake Rotor Kit For VW Jetta 2019
Designed for VW Jetta 2019, this 4-piece front/rear rotor set supports direct replacement of the brake friction surface. It is best for modern VW applications where stock rotor dimensions are needed. A limitation to note is that this kit focuses on rotor replacement and may require additional calipers or hardware for a complete upgrade on non-standard setups.
Who it’s best for: VW owners looking for direct-fit, rotor-only replacements to refresh braking performance on newer models. Choose this if you want to refresh rotors with VW-specific dimensions.
Speedway Motors Deluxe 1964-74 GM Front Spindle and Disc Brake Kit
Complete front disc brake upgrade for 1964-74 GM A/F/X bodies. Includes stock-height disk brake spindles, 11″ vented rotors, GM-style calipers, brackets, pads, bearings, seals, hoses, and hardware. This kit is best for GM builds seeking a comprehensive, bolt-on upgrade with minimal modification. A potential limitation is the need to verify fitment with non-GM hubs or aftermarket wheels.

Buying Guide
What to consider when selecting a classic disc brake conversion kit:
- Vehicle compatibility: Confirm spindle type, lug pattern, and wheel size to avoid misfit issues. For VW, prioritize kits advertised for stock VW spindles or 5×130/5×4.75 patterns.
- Complete kit vs. rotor-only: Decide if you need rotors, calipers, bearings, seals, and hardware included or if you can source components separately.
- Bolts and threads: Check thread sizes (often 14mm on VW) and compatibility with existing hardware to ensure a smooth installation.
- Wheel clearances: Ensure your wheels have enough offset and diameter for new rotors and calipers; larger discs may require clearancing or different wheel choices.
- Driving needs: For daily driving, prioritize kits with vented rotors and reliable caliper setups. For show builds, stock-like aesthetics with strong braking may be preferred.
