Default Darting when applying brakes

Ok, I've looked and don't see a mention of this, so I gotta ask- is it normal for the xfire to dart left or right when braking on less than perfect roads? I have only noticed it on somewhat challenged paved roads, but sometimes the wheel is almost jerked out of my hand. I have never had a vehicle to do this, and the only sports car I have owned before the xfire was a vette, and it didn't do this....

thanks

I found that to be true when I was still running the stock Continentals. Since I replaced them I do not have that issue at all.

i bet a hundred bucks your steering damper is bad. they tend to leak badly. my car does the same thing.

When I first got the car, I noticed that at stop lights, the wheel would turn pretty far to the right. No other car I've driven has done that. I have since gotten used to it. I suppose it's normal.

this is a common issue in Crossfires for at least two reasons:

1. wide tires
2. short wheelbase

i used to have a 95 corvette and it did the same thing. it's most noticeable when stopping at red lights where heavy traffic has gradually worn down the road surface resulting in "valleys" where the vehicle tires travel. a wider tire has to flex more in conforming to the curvature of the surface so it is more susceptible to wandering. the tendency to wander is exagerated by the short wheelbase. the rear wheels want to follow the front wheels, and the closer they are together, the more the vehicle will dart back and forth.

Boy, I can attest to that. In west Alabama, US 80 is the most-travelled road heading from Montgomery to Mississippi and points west, and the "Truckers Trench" is just awful. A hard stop will find you all over the road.
I always drive in the right lane (non-passsing) except for about 60 miles of this road. It almost feels like an alignment or brake preoblem, but it isn't!

I have also noticed this problem. Its not so much that it bothers me, but I just didn't know if it was a problem or not.

My car doesn't "dart" but it does "pull gently" to the right when I am pushing the brakes 100% to slow from 100mph to 40mph.

Since I only do this kind of braking at the racetrack, it doesn't bother me that much.

Had this problem when I got new tires. Car kind-a drifted to the left also. Rotated(swapped) the two front ires and it went away. Tires weren't symetrical or any thing like that but it sill made a difference.

What Rob M says is true. All three of mine do it when coming to a stop where truck traffic has left ruts in the pavement.
