Stasi, Just a quick bit of info from a FWD road racer. It's long been established, by Doug Peterson of Comptech, that 60/40 is optimum weight dist. for a FWD car. If you go 50/50 you just can't get the power down, but I would think this could help us get to 60/40. What is the weight difference between a Zetec and a Duratec? Isn't the Zetec an iron block? I'm thinking that it may not be much since the Duratech is an aluminium block.
