AR bar sizing is a minefield if you don't have the knowledge to set them up. The easiest way to think of the effect an AR bar has is to imagine that the AR bar persuades the vehicle to go straight on in a corner. Principally, the AR bars are there to restrict the suspension movement in roll so as not to give unwanted suspension angles, usually in camber.

So a front AR bar will mean understeer i.e. ploughing straight on when you want to turn a corner.

And a rear AR bar will mean that the rear wants to go straight on when you want to turn a corner i.e. oversteer.

The front/rear balance is a fine one and getting it wrong is easy and potentially fatal! A car with no AR bars is probably safer than one with unsuitable ones front and rear. If you don't know how to set them up buy a package from say Whiteline.
