Anti-roll bar combination

[aircured]

I have read a few threads regarding the use of beefed up anti-roll / sway bars, but some of the threads contradict each other.

One says that the rear anti-roll / sway bars should not be bigger than the front bar. YET the other thread says it the opposite way round.

I am looking to up-grade both the front and rear bars but I am confused, can somebody point me in the right direction.

you normaly want a bigger anti roll bar on the front. that way you keep the balance of the car the same. if you want a car that snap over steers and is harder to control then go bigger on the rear bar, not recomended.
you dont say what car your running as i wouldn't run a rear on a swing axle car.
for road use i wouldn't go above a 19mm front and a 14mm rear on a 1302/3
for a swing axle car a 19mm front and a modefied z bar would be my prefered set up.

Agreed.
Just think of the anti-roll bars as inducing the axle they are fitted to wanting to carry on in a straight line. That means on the front that it will understeer but on the rear it will induce oversteer since the rear axle will want to go straight on when the front is turning the corner i.e. oversteer. The amount of understeer/oversteer is govened bu the stiffness of the bar, which is determined by the thickness and the operating length of the lever arm.
