Weld On Rear Brake Caliper Adapters for BMW E46 E36 323i 325i

Weld-On Rear Brake Caliper Adapters for BMW E36 & E46

Give your BMW drifting or performance build precise rear braking control with these weld-on twin brake caliper adapters. Engineered for the E36 and E46 chassis, each bracket mounts directly to the stock rear trailing arm, allowing you to secure a second factory-caliber rear brake caliper. This setup creates an independent hydraulic circuit ideal for hydraulic handbrakes or dedicated drift configurations.

Built for Demanding Tracks

Cut from 0.5-inch (12 mm) high-strength steel and finished in a protective silver coating, these plates deliver the structural rigidity needed to handle repeated lateral forces. The geometry aligns perfectly with OEM E36/E46 calipers and disc brake suspension arms, providing a reliable secondary rear brake solution that integrates cleanly with existing chassis components.

Benefits & Installation Tips

• Pair with a factory brake caliper from a matching BMW platform to establish a robust, tunable secondary rear brake system.
• Plan ahead for installation: remove the original ABS sensor early and schedule dust shield trimming to ensure proper caliper clearance.
• Install both brackets symmetrically on the left and right trailing arms to maintain consistent pedal travel and balanced brake bias.

Product Specifications

• Vehicle Compatibility: BMW E36 and E46 rear trailing arms (excludes Compact and 318ti models)
• Construction Material: 12 mm (0.5 inch) high-strength steel with silver finish
• Primary Application: Drift builds, hydraulic handbrake integration, independent rear brake circuits
• Required Components: Factory-fit rear brake caliper from a BMW with matching engine displacement and rotor diameter
• Mounting Method: Direct weld-on plate, requires ABS sensor rerouting and brake dust shield modification

Package includes:

• 2x Weld-On Drift Twin Brake Caliper Adapters

Important Pre-Installation Reminders

ABS sensor relocation is mandatory for safe operation.These adapters accept only factory brake calipers from comparable BMW platforms sharing the same engine code or rotor diameter.
Dust shield modification will be necessary to clear the caliper body and ensure unrestricted piston movement.
