325iX front and rear diffs: aftermarket RSX Torsen units through Random Industries

A 2024 r3v thread lists replacements for NLA 325iX drivetrain parts. RSX Racing Solutions (Spain) makes a front LSD (about $845) and a matching rear Torsen diff (about $971), sold in the US through Devon Eyerman / Random Industries LLC (Michigan). The same seller rebuilds the center viscous coupler (about $850 plus a $250 core). These are upgrades that replace the BMW units, not BMW parts; prices are as posted in 2024.
