you need to be carefull adding stuff to gearbox and diff oil or even changing grades etc. as syncro\'s and clutch packs etc. in diffs are designed to work with certain oils. I know I put a different grade of oil in my 323 box and it was very notchy until it warmed up. Aslo clutch type LSD\'s can be damaged if the wrong oil is used as the clutches will slip (not that the Rx7 or rx8 have a clutch type lsd as standard)

I would say no Bob as the synchro\'s need a certain amount of friction to work. Unless your running a crash box that is.
