From our IM discussion:

Irish44J: yes, it creates understeer. but the "ideal" setup for a car is with slight understeer (that is the safest way to have it). That said, the LTB should only be used in conjunction with a RSB (which creates oversteer)....they are complimentary
Irish44J: no, it is NOT detrimental to handling when combined with a RSB
StAtiXz6: and when combined with a FSTB?
Irish44J: understeer=front end loses traction before rear. oversteer-the rear end loses traction first. In a front-wheel-drive car, it is preferable for the front end to slide first, since you can recover easily by hitting the gas
Irish44J: FSTB doesn't make much of a difference
StAtiXz6: what happens when the car doesnt have this understeer?
StAtiXz6: handling is to sensitive?
Irish44J: well, a balanced setup is good too, but difficult to get
Irish44J: the opposite of understeer is oversteer
StAtiXz6: ok so if u dont have understeer u have oversteer
Irish44J: oversteer is dangerous in emergency maneuvers - can cause TOTAL loss of control.
Irish44J: yes
StAtiXz6: ok so basically its better to have a LTB then to not have one
Irish44J: if you have a RSB, yes.
Irish44J: Maxima stock has moderate understeer
Irish44J: Maxima with RSB and Stage 2 LTB has low-moderate understeer
Irish44J: Maxima with RSB and Stage 1 LTB has minor understeer
Irish44J: unless you have springs and adjustable struts, i'd suggest a stage 1 LTB

Irish44J: understand now?
StAtiXz6: yeah because i had a whole different understanding
StAtiXz6: im planning on getting the RSB at the same time as the FSTB
Irish44J: good idea.
StAtiXz6: then drop a LTB stage 1 because i dont have the aftermarket springs/struts
Irish44J: FSTB doesn't really affect over/understeer in my opinion, it is simply a frame stiffening
Irish44J: Yeah, the stage 2 adds too much stiffness probably for stock springs/struts
Irish44J: will make the car feel "wierd" for lack of a better word
Irish44J: The way my car is set up right now, I can slide the front tires before the back breaks loose....that's the way it's safest...
StAtiXz6: ok
StAtiXz6: so i just myaswell drop all 3 at the same time
StAtiXz6: ltb, fstb, and rsb
Irish44J: I would GET them all at the same time, but put 1 on at a time, so you can feel the way each individual component affects the handling - good way of learning what each component does for the car...

slammed, do you have a LTB?

Because I do. And I can tell you, that there is significantly more understeer WITH the bar than without. I agree that it is essentially a frame stiffening, but it also stiffens the flex in suspension components....

irish do you have the stage I or II. Some time in the future I wanted the stage 2 along with a RSB, but my GR2s aren't adjustable. Will that be a huge factor in your opinion?

Irish: you have one thing incorrect. Trying to recover from understeer by hitting the gas will only cause MORE understeer.....Understeer happens because you have exceeded the limits of the friction circle of the front tires in one or more directions. Adding throttle only makes things worse.

Also, with regard to your setup theory, you are correct for 95% of the people out there driving. Understeer at the limit is indeed safer. However, for the 5% with high skill levels in car control, the understeer setup proves to be a major hindrance.

yeah, I mis-stated....I meant to say with a front wheel drive car, you recover from a spinout by reversing the turn and giving it some gas....not just punch the gas in the same direction...you know what I'm saying.

as to the 95% vs. 5% I'd tend to agree there...though I have my setup balanced for almost no understeer....if I turn my front struts up to 4 I'm perfectly balanced...but I keep them at 3 to keep some light u/s in daily driving on the madhouse we affectionately call "the beltway"
