Ok so new engines on the way, car is used primarily for drifting.

Was going to go with "Silkolene PRO S 10W-50 Ester Synthetic Oil" for the engine oil:

I'm not sure what oil you'd reccomend for the gearbox whilst it's out? Please advise.

Also, I'll stick a new oil filter on obviously and some fresh coolant.
