BMW E46/E92 M3 Block Disc Pack – 100% Locked Differential for Drift & Drag

Transform your BMW E46 or E92 M3 into a drift or drag beast with RacingDiffs’ Block Disc pack, designed to give your Limited Slip Differential (LSD) a 100% lock. Perfect for drift enthusiasts seeking the performance of a welded differential or drag racers aiming for maximum traction at launch, this upgrade ensures your differential remains locked at all times.

Unlike welded diffs, our Block Disc set offers reliability and flexibility. Made from high-strength materials and backed by a Lifetime Warranty, the discs won’t crack under extreme pressure. Plus, you can easily revert your differential back to its LSD configuration anytime by simply removing the discs and reinstalling the clutch plates—no permanent modifications required.
