Does this dual caliper setup even work?
After an entire drift season of testing, I’m finally ready to share the results of one of Feint’s first R&D projects: a dual rear brake caliper kit for the BMW E46.
The goal was simple—develop a bolt-on solution that works with a standalone hydraulic handbrake while retaining the factory parking brake mechanism and wheel speed sensors. No welding, no cutting, and no unnecessary modifications.
The system uses Strange two-piston calipers paired with a custom bridge and mounting bracket that adapts them to the stock E46 330 brake rotor. The bridge also ties the calipers together, increasing rigidity and potentially acting as a heat sink to dissipate heat.
The biggest question, of course, was whether it would actually perform.
After a full season of use, the results were encouraging. The factory foot brake retained its normal feel, brake bias remained predictable, the hydraulic handbrake consistently locked the rear wheels, and the pads showed very little wear. Outside of changing to a more corrosion-resistant hardware coating, the design required very few revisions.
This video documents the prototype, the reasoning behind the design, and the results from real-world testing. If you’re interested in seeing this kit reach production, we’re currently building a pre-order list.
