Is there any milage in using a 'box oil cooler to prolong it's life? Type RA box V2. Hard road use and nurburgring action.

Was also thinking about having the gearset cryogenically treated. Has anyone done this, or know where to get it done? If its a good idea.

 

I was looking at an box oil cooler but not done anything with it yet...

Once I've got my engine and box mounts sorted so they can handle the torque figure, I'll prob look at this again.
