Get any TC without sways where the handling is OK, then fit one to the front and try it...the car will push like crazy; or just fit one to the rear and the car will fishtail
1) You put swaybars on both ends of a vehicle
and
2) drive your car (fullsize one) agressively on an autocross circuit. now find a modshop and look for a swaybar kit specifically designed for your vehicle and install it (or have someone install it for you) and drive your vehicle at the autocross track again. Don't drive it conservatively like you would in normal everyday traffic, drive it like you truly are on a racetrack and drive agressively, you'll notice a big difference on your car's handling, especially on a front wheel drive vehicle, you'll see that you've had alleviated some of your understeer, aswell have your vehicle's camber tuned, you'll notice an increase in traction and sharper on-power steering than you would if you haven't. Now tied that onto cars a 10th the size of your fullsize, chances are the results will be similar, unless you drive very conservatively and don't drive with a racing line in mind.
I think the reason why your car is pushing like crazy when you've got swaybars on is because your car doesn't have any traction at all and your camber isn't dialed. Try using rubber or foam tires and try grip driving for once. Using PVC on your wheels will for sure cause you to push when you've got swaybars, but when your tires actually have traction, then yes, it will alleviate the push.
Here's a quote from a friend:
"on a high traction surface swaybars help by reducing chassis roll, on a lower traction surface you need a bit of chassis roll to maintain traction so lighter or no swaybars would be requiered. that's the simple explanation".
Therefore, if you're speaking of high traction surfaces, a swaybar would be of great help allowing less body roll and weight transfer so that a vehicle may have more equal weight to each of the four tires therefore sharper turning because there is much traction to utilize. On a low traction surface, body roll would be helpful in allowing weight to transfer to one side of the of the vehicle so that even the most minimum amount of traction you have is going towards forward movement and the angle of your tire being steered.
