So I am coming up on 30k miles in my 2015 Z, and it's probably time to change out differential, transmission, brake, and clutch fluids. Just got my oil changed at the dealership today at 26.9k miles and they wanted close to $1k just to change differential and brake fluids along with some fuel system cleaning and 'decarbonization'. I just laughed...
In any event, what are the proper high performance fluids for transmission, differential, and clutch?? Brakes are easy, but want to see what's proven for these other components...
Figure I can purchase all the fluids separately, and take them to my local performance shop who has installed several mods for me. Know they will charge me reasonably for the labor. Appreciate the help greatly...
