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.
