  • BMW E36 Diff Brace & Rear Cover Reinforcement

    RD7010

    Stop the “pumpkin-ear” problem for good — E36 Differential Brace

    Hard launches, clutch kicks and sticky tires can crack the thin aluminum ears on an E36 rear-diff cover, ripping threads out of the subframe and ending your track session early. The RacingDiffs Differential Brace eliminates that weak point by distributing torque through a laser-cut steel plate that ties both cover ears directly into the subframe.

    Features
    • Laser-cut 3 mm steel: Zinc-plated for corrosion resistance and stiffness under shock loads.
    • Complete hardware: Grade 10.9 bolts and CNC-machined spacers included—no extra trips for parts.
    • Bolt-on install: Under an hour; no welding and full access retained to ABS/speed sensor.
    • Bushing-agnostic: Works with OEM rubber or solid diff bushings.
    • Track-tested: Proven on drift, time-attack and turbo builds up to 1000 Nm.
    Performance Benefits
    • Prevents ear cracking and thread pull-out on the diff cover.
    • Distributes torque loads into the subframe to protect the housing.
    • Improves reliability for hard launches, clutch kicks, sticky tires and high-grip setups.
    • Peace of mind for track days, drift events and high-power street cars.
