A finned cover would not help much. Nearly half of the diff sits in the cradle. Not to mention the movement the differential has in the cradle with the factory bushings.
My journey of tracking and the diff temp sensor on my 16GTPP. I received the light the first time on the car in nearly stock form(only a SW catback). This was mostly due to hot lapping the car. Car sat for only 5 mins and then it was back out on a short track.
After that I changed the fluid to amsoil (factory equivalent weight) and wrapped the exhaust. Never got the temp warning again until I did long tube headers.
My thought is that the cats on the factory system were holding a lot of the heat. Hence why I also found melted wire looms when removing the factory exhaust manifold/cat near the placement of the cat.
With the long tube headers, stiffer suspension(shocks, springs & sway bars) I was getting the temp sensor to hit after about 12-13 mins of a session at Hallett Mortor Raceway in June. Granted it was warm that day, with a high of 90°. I believe the long tubes with no cats and minimum restriction is allowing more thermal energy to travel down the system. Also the fact that the suspension got a bit stiffer could play into things as well.
Nonetheless I came the conclusion that it was necessary to add a cooler.
I ordered the Full Tilt Boogie Kit during their Black Friday special. Everyone I have seen use it has seen great results.
If I was contemplating a new PP1 or PP2 I would first change the fluid to amsoil 75w-140 and wrap the exhaust. Nothing permanent, overly substantial, or costly. Then go do a couple of track days and see if you get the prompt to come up.
Yea I wasnt talking about a finned cover but the ones that have provisions for the cooler.
I see them available with a cooling kit but havent seen them seperately
