24mm sway in front and 23mm in the rear

[fuji]

How do you think this combination will handle??? Too much sway bar???

[Sabretooth]

hmm,

Well by the concept of what a sway bar does, you just created a setup has very little body roll, but should understeer as the car would naturally. Purpose of the rear sway bar is to allow the rear end to "firm up" to allow the car to understeer less. By adding another sway bar, this time to the front. It kinda nulls the point of adding your rear sway bar, or making it worse in the understeer catagory.

Only genuine benefit I can see offhand without having a car to test it on, very little understeer.


Hopefully someone can chime in and help you out a whole lot on this more than I can.

You mean "very little body roll". The car will, as you said, understeer.

You pretty well covered it.

That is a huge benefit, and in mild to moderate driving makes the car really fun to drive. At the limits of traction (or in emergency conditions), however, understeer and oversteer become a major handling factor.

Hmm understeer can be kinda fun sometimes but then very scarry and unpredictable at other times. The kind of your heart drops to your stomach id personally rather have oversteer that is easier for me atleast to correct.

Does anyone know how thick the stock sway bar is?

*shrug* go outside with a micrometer?

You most got it backwards....

Nothing fun about understeer.... and is more predictable and easier to control to the average driver... Natural reaction for most of the people would be to release the gas and touch the brakes making the front tires grip again.

Oversteer in the other hand can be fun for a driver who know what it is doing...

I doubt it. Granted with chassis bracing you will have less body flex/better transfer of power, but not sure how that would work on fwd car

[cali yaris]

anything that keeps the car from rocking backwards on launch and during shifts is good for 1/4 mile times. However, sway bars do not accomplish that task - springs, shocks and engine mounts do.

Stiffer springs in the back would decrease the weight transfer to the back of the car during the launch. Ideally you will want the front of the car to seat a little lower than the back of the car.

On a FWD car for drag racing you want to keep the weight of the car in the front... avoiding as much as possible the weight transfer to the back.

So stiffer and higher springs in the back.

[IllusionX]

castrex is absolutely right.


and larger sway bar in the front will result in even greater understeer. I suggest not touching the front sway bar until your car is always OVERSTEERING.

I have to think that the material a manufacturer chooses has as much effect on the performance of an anti-swaybar as its diameter. Other factors could also come into play (shape, arm length/leverage factor, etc)

So, one manufacturers 24mm bar may offer the same qualities of anothers 22mm product.
Trail and error may be necessary when mixing brands.

While the idea here makes sense, it's not true. Swaybars are all made from steel, and the different types and grades of steel are of such little significance to the equation that they aren't even considered by engineers. The stiffness of the steel is a "constant" in the equation.

Unless you're building swaybars out of aluminum (dumb idea, aluminum doesn't make a good spring) or titanium ($$$$) or carbon fiber ($$$$$), swaybars of the same basic shape can be compared based primarily on their diameter.

Three things, really:
1. Diameter
2. Hollow or not (same diameter, but hollow = slightly less rate)
3. Length of lever arms.

the zero to 60 time after springs/shocks went from 10.0 secs to 8.8 secs during our track testing for the Tokico HTS shocks.

nice

I wouldn't want a havier sway bar up front, you are only going to increase the alreasy bad understeeer problems this car has
