Can any one tell me or know the facts about 4wd evo's do all 4 wheels have the same ratio's and all 4 wheels spin at the same speed. People tell me the front spin faster or the back spin faster and my mate reackons its impossible all four must spin at the same speed. So the question I asking is does anyone know the deal and can I have abit of a technical answer so when I tell my mate I have the facts to prove it thank you.

 

All of the wheels spin at the same revolutions at any given time, however, in awd or 4wd vehicles, the thing is power ratios, 50/50 means the engine is putting equal power to both the front and rear. It's possible thru ecu or mechanics, to alter that ratio, such as 40/60, 20/80...
