Default Sway bar question?

I don't know if you guys experienced this... on stock suspension, do you guys get a sudden weaving if you hit an uneven road or so on. Similar to a hydroplane effect but lesser degree. Sometimes if I want to floor my car at speeds, I fear that my wheel will jerk. My friends say get a Sway bar set up.Any ideas?

Called bump steer. In engine swaps it happens if the steering rack is lowered without compensating for it. I'd look for worn joints on your tie rod ends.

Or...what size tires do your have...larger than stock sized tires can cause the wheel so sometimes 'wander'..I forget the name for it..But Im guessing since you only have 20 posts the car might be new to you .....

Bump steer Defintion:
Bump steer is the tendency for the tire hitting a bump to momentarily change its toe-in setting, which causes the car to feel like someone turned the steering wheel a bit. This happens due to the tires’ suspension going up and down over the bump. The steering arm is attached to the body of the car at one end, and the suspension at the other end. So it travels in an arc. When a rod with one anchored end travels in an arc, the effective length of the rod changes. This is what pulls on the wheel and makes it feel as though someone besides the driver is steering the thing.

Sway bars won't really help the car swaying back and forth while on harsh pavement. They help counter body roll. One of the end links on the front loosened up somehow on mine. I noticed it was rolling too much but it didn't wander any more than normal. Upgraded shocks will help the car from feeling especially wishy washy because the stock ones suck. Wide tires cause the car to wander some. Put some better shocks on it and check the alignment.

I definately get the tire-wander effect with my tires. I have Toyo 275/35/18's all around, and if they find a groove in the road, they're perfectly happy to follow it.

Same here - I have custom re-valved Bilstein HD shocks & suspension setup recommended by Strano. All was fine (actually much better then stock WS6 handling) until I changed to 315/35-17 rear tires. Then the car started to do just what your are describing. It's called 'trammeling'. I called Strano, he asked why I added wider rears, I stated for traction (still don't have much - but better!) + looks. He said that if I insist on running the wide tires - lower the air pressure from the 35psi I was running and that it would help alleviate the problem - it does.

Rut-following, sometimes called trameling. It's casued by low-profile tires. You will get used to it and not even notice it. Or you can put some tall skinny pizza cutter tires on your car and eliminate it. Put some 215/65's on there and and presto, zero trameling. You have to decide, is this a race car, luxury car, or something in between?

I can't believe you guys run 35+, and 40 psi in your tires. I maybe run 32 sometimes. 30 is normal for me. I had a set of tires mounted on a daily driver ine time, and the shop put 45 psi in there. It was like riding around on basketballs.
