I have not qualified for the 24HRS of LeMans so my diffy will have to continue to run sans
oil cooler. I think I could branch off my rear brake cooling ducts and provide a little ram air cooling to the housing at track speeds ?? Doesn't help much on PCH in stop and go traffic........I have seen small coolers for less but I can believe someone going over 1K. I asked the question to Nick because I respect his knowledge.
