I've begun investigating diff cooling options. Pump/cooler/routing.

Anyone have any tips on 3.0si diff cooler mounting and installation? I may have seen one or two guides online for a E46M, but curious if anyone on this forum has done it to non-M diff.

I assume that routing should be simple enough: feed line to the lower drain bolt, and return line to the upper drain bolt.

Also,since my rear floor is completely covered with a diffuser plate going up to about where the floor plan starts, I have no where to mount a cooler. I've seen folks mount cooler inside the trunk with an aux fan. Any thoughts on this?

Prefer anyone who has experience with doing this and races their z4!
