BMW E36 Diff Brace & Rear Cover Reinforcement

Stop the “pumpkin-ear” problem for good

Hard launches, clutch kicks and sticky tires can crack the thin aluminum ears on an E36 rear-diff cover, tearing threads out of the subframe and ending your track day 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.
