Stabilizer Bars - Do they worth the money?

Material used is "spring-steel" (dunno what the correct English term is). 90% of the ae86 bars will be solid, but calculation is mostly the same between hollow and solid bars, just different way of calculating the polar moment.

@domi:
On a smooth track surface (not all tracks are like this), You can get away with the arb's coupling effects..hell ae86's have a solid axle in the back any way, so who cares. You can get a pretty nice dual use setup if you take the thickest arb's that you can find. Get a set of springrates that suits your daily driving and doesn't need arb's for balance. At the track, reconnect the arb's and jack up the shocks. For trackdriving you want a slightly higher front roll couple (more understeer bias), so probably just the front bar would do. For drift practice add a thick rear bar too. To make any significant difference you would really need the stiffness of a hollow front bar.
Otherwise, just add a set of solid sways and be done with it, they wont hurt daily driving that much, certainly not in the USA. I'll throw down the calculations (simple ones) for arb stiffness this afternoon, so everyone can get a relative feel for the difference. I would need suspension geometry data to calculate wheelrate and equivalent spring rate, so that will take a while.
