Ok BMW Race Fans! Racing Diffs has some goodies for you aswell! Introducing the BMW Rear Differential Steel Cap Upgrade!
Available for the E20-E30, E36-Z3 and E46 M3 these “LSD Steel Caps” address a lot of issues with breakage of standard the 168mm limited slip differential caps and allow a serious level of performance to be achieved for the 188mm rear differentials.
Their heavy duty construction makes them ideal of multiple LSD clutch upgrades for the E36/ Z3 and E46 BMW rear differentials and allows a ton more support to reduce damage due to abrupt torsional load excreted on the LSD, increasing clamping loads and distributing TQ to the wheels where it belongs.
