I have a BMR K-member with stock A-arms and steering rack

My alignment was set with the car sitting at normal ride height to;
Toe 0
Caster 0
Camber 5

I have the front jack up now with both wheels off the ground and notice a very positive toe out condition. When I had the front-end align I did not follow Madman advice to raise the front until both wheels leave the ground and then pull the front down with a comealong and check that during the full travel range the toe never goes out.

What can be done to eliminate or reduce the amount the will change, throughout the total front-end travel range?

What is the fix?
Will adding BMR lower A-arm fix this issue?
Adding a spacer to lower the tie rod attach point that I see on a lot of f-body drag only cars?

YOu need to have the bump steer adjusted.

 

SlickVert, Do you have your Caster and Camber listed backwards? You need more Caster, at least +3 or +4, for drag racing +6 would be better. 0 Camber is fine or a little bit negative (tire tilts in slightly at top). The Toe can be 0, but around 1/32 each side would be better. Bump steer definitely needs to be eliminated.

 

Yea, I sure did type it wrong.
I do have about 5 caster and 1/16 total toe in.
Thanks for the info, this site is great.

I just got off the phone with Wolf and Brian (Madman) @ Thunder Racing and you all are saying the same think Bump Stops.

Madman recommended getting the Bear bump stops, they will work with my stock steering rack.

Thanks guys

also set your adjustments not as if the car is sitting still but at ride height under power slightly jacked up.

 

Good point
Thanks
Bob
