I've read all the rear sway bar threads pros and cons. I understand "oversteer vs "understeer". Let me use an example of a couple of 90 degree esses I like to play with locally. I have a stock '85 notch. Coming into the first "s" fast it whips right around the corner great but the rear will let go a little coming out. So, the rear bar will make the car understeer but will keep the rear from washing out. Is that correct?

What will a bigger bar on the front only do for me? I don't seem to have an oversteer or understeer problem the was it is. A bar on the rear will tend to drive the car straight when coming into the corner, correct?

Thanks

The rear bar will make the rear come out worse. Oversteer is when the rear whips out.

Most mid-engine lay out's naturally ride like they are on rails. The problem with Fiero's and MR2's is the lift off over steer. That is, when you lift off the gas in a corner, the rear likes to slide out. Best way to deal with this is staying on the gas, or downshifting.

If you've seen the Motorweek review of the fiero on youtube, you've heard them talk about this.

BTW, sway bar's only came on the 88' model year with the Formula and the GT. (It might have come on the base model, but I highly doubt it.)

2.5 is correct with making the sway bar add more over steer as well.

An anti-roll bar takes traction away from the end of the car it is installed on.

Add a bar to the rear of a car that didn't have one and the back of the car will feel loose.
Put a bigger bar on the front of a car - the back of the car will tighten up.

Allow me to share my opinion. The rear anti-sway bar on my 87GT 3800Sc remarkably improved the traction and handling of my Fiero but since I used the larger diam Addco bar it did over steer until I installed the matching front Addco bar. My other Fiero has the smaller diam..Herb Adams/ Fiero Store design. That one works well stand alone.

Try increasing the pressure in the rear tires by a few a few pounds.

I put the front anti-sway bar from an 84 on the rear of my 85 GT. It behaves perfectly.

The "plowing" is gone. It steers neutral. Of course with a mid engine with a wide stance, the back end can come out quickly if you hit the gas in a turn, but that is just getting to know your car.
