I found that a relatively light Toyota on 11.5 or wider tires actually handles *better* in emergency situations without the sway bar installed (at least the older generations with no rear sway bar). This sway bar only controls the front end of the truck, and sharp cornering will put most of the weight transfer onto the outer front wheel of the truck, while the outer rear does not see the same transfer of weight. This can result in SEVERE over steer, causing the rear end to suddenly and violently whip out from behind you without warning, especially on wet pavement.

I spun my 87 4Runner around the first time I made a right turn on wet pavement, and several more times in the first two years of ownership. Once the sway bar was removed, the cornering became much more predictable... I have yet to spin out again in the 9 years since removal. <img src="/forums/images/graemlins/kewl.gif" alt="" />
