Rear end spool

[135iTX]

Do any companies make rear end spools for the e8x/e9x chassis? I've seen options available for older model BMWs but nothing for the E chassis.

This would be nice as all i do is roll race, and id stop snapping driver side axles. 5 as of now. Better than welding the diff i would assume as well. And cheaper than a mfactory or m3 lsd swap. Or even a 8.8 swap.
