[Fot] tr4a diff covers

 FWIW, the smart guys run an oil cooler and oil pump. Synthetic works great up to a point. Then kerblammo.
Diffs run HOT.

 We have experience with this on the Tx endurance TR6 car. Anything over a 30-45 sprint race and you need to be running full synthetic gear oil. If not, you will melt diff mounts, puke all gear oil out of the diff, burn up bearings…all sorts of failures that we had never experienced with vintage sprint races. 
So if you plan on any endurance racing, go for the extra fluid capacity and use synthetic. If a road car or just sprint races, probably doesn’t mater.
