I've noticed that I've been feeling a lot more bumpsteer lately when going over bumps. When I hit a bump in the road, the steering wheel will jerk around a little bit. I have the Nismo S-Tune suspension installed, along with some Eibach sways. I have the sways set at the loosest setting in the front, and the middle setting in the rear. I didn't notice the bumpsteer when these were first installed. Can anyone shed some light on what could be causing it, or if there is anything I can do about it.
Also, here are my alignment specs:
Front Toe In: 1/32
Rear Toe In: 1/8
Rear Camber: -2 degrees

Thanks.

 

Bump for my bumpsteer question.

 

I have the same problem. I think it was always there, but I have really started noticing it after I installed my Hotchkis sway bars. Though I wouldn't think they would have anything to do with it though, maybe it is all in my head.

 

I have the stock suspension, and I have been feeling it lately, too.

 

ditto on stock and feeling it

 

How are your tires doing?

I noticed that when my front tires started getting down to slicks, the car was much more skittish over rough areas. It would be more likely to want to skuttle around a bit. It could be something like that.

Also, as the shocks wear, they might allow the tire to lift off the road a bit, which would unsettle the vehicle.

Finally, what about alignment? If your car is always pulling in one direction, then you will be applying a light oppsite force to compensate. When going over bumps, the car will usually do a little side to side dance because of this (happens to me on cambered roads).

Anyhow, those are the things that come readily to mind.

Good luck!

-D'oh!
