Maybe I have had a man look like the Mr's says about everything I apparently search for....but I did a basic search and some trawling on oils to use car wide....found not much.

20V Black top with warm mods, anyone got preference on oil brand and oil specs of what works for track use along with filter brands (running oil cooler and high flow pump/catch can etc)?
Next on the list is gearbox oil, T50. I read ages back some were having issues with different brands of gearbox oil....again anyone got suggestions?
Finally, Diff oil. Toyota LSD, track use, what are we using mostly?

Break fluid wise I was going to go with the motul high temp end.....maybe change out the pads while there but they are about half way through so the can't be arsed factor is moderate (till I squeeze the breaks that first time turn 1).
Radiator wise, I was looking to flush and place in something more suited to Aust conditions than the Jap fluids currently on board.

In use for sprints, circuit and maybe motorkarnz but not drift.
