Front Ball Joint Disc Brake Conversion Kit (4x130) - VW Beetle & Karmann Ghia

Front Disc Brake Conversion Kit (4-Lug) – Bolt-On Style

Modernize your classic's braking performance with our In-House Front Disc Brake Conversion Kit. This curated assembly is designed for those who want the reliability of disc brakes without the hassle of changing spindles. Unlike generic market kits, this setup uses heavy-duty cast brackets that bolt directly to your factory drum-brake spindles. This provides a straightforward installation that delivers immediate improvements in brake modulation and fade resistance.

Please note that this kit features a track widening of approximately 1/4" total. This minor offset is a result of the high-strength rotor and bracket geometry required to fit the stock drum spindles. It is the perfect balance for enthusiasts looking for a "bolt-on and go" safety upgrade while maintaining the original 4x130mm lug pattern.

Technical Specifications

• In-House Compiled Kit: Curated components for maximum reliability.

• Offset: Widens track by approx. 1/4" total.

• Lug Pattern: 4 x 130mm (14x1.5mm threads).

• Requirements: Minimum 15" wheels; must be used with stock drum spindles only.

Installation & Maintenance Tips

• Reuse Spindle Hardware: The caliper mounting brackets utilize your original backing plate hardware for installation onto the spindle. Ensure these bolts are clean and in good structural condition.

• Wheel Studs: This kit is designed for use with your factory lug bolts or aftermarket studs (not included). Always verify thread engagement (minimum 6–8 full turns) before driving.

• Track Width Adjustment: Because this kit widens the track by 1/4" per side, check fender-to-tire clearance if you are running oversized tires or a significantly lowered suspension.

• Proper Lubrication: Be sure to pack the included wheel bearings with a high-temperature disc brake grease. Conventional drum-only grease may break down under the higher heat generated by disc systems.
