How much of a difference would two 15mm spacers on the rear of the car make for handling? I'm hoping by widening the rear, i wont have to worry so much about snap over steer.
That's really the wrong analogy, since the lighter rear end of a FWD car is the opposite of the heavy weight at the end of a pendulum. It's more like those blow up clowns that you punch and keep popping back up.^^ That is true. Also though, think of the rear being a pendulum, it acts that way because there is less weight.
