white line makes the best four mk3 or so iv been told by others who have tryed variouse one. somthing that might be good is toe kit that says it can handle the extra stress of a bigger sway bar. iv seen one on hpf correct me if im wrong

Note that '89+ use plastic end links. When using a significantly tighter anti-sway bar they may break.

so whith 88 and 87 dont worry to much about it? dident know they used plasitc in 89

Unless they've been replaced '88 and earlier will have metal end links.

thats cool little fact to know, u think the 87 will handle a whitle line 30mm swaybar whith no issues then?

Should be just fine. I can't remember if that bar has multiple mount points for the end links like the ST... If it does I'd recommend not using the stiffer settings except for track days.

i bet even on its softest setting its probably much stiffer than factory, cant wait to see it in its stiffest setting

Use caution. I can't remember if it plagued the MKIII Supra but some other Toyota's were found to have other things break if the anti-sway bar was too stiff.

So how do I know which sway bar to buy? The other car I want is a Toyota Century, dress up my brother and get him to drive me around *grins*

Depends on just how tight you want the ride. If you just want firmer handling in the turns but only a little difference over stock in ride quality the rest of the time, I'd just go with ST and play with the low and medium settings. No need for a super beefy bar unless you're regularly taking the car to the track on weekends.
