Howdy.

Can anyone advise a cost effective place to purchase Bump Steer Spacers?

thanks

thay lower your lca's to combat bump steer that lowered datsuns experience once the lca's go horizontal

Im not sure I'm not sure that is actually true.
The spacers I have seen are Front Roll centre modifiers, i.e raise the front instant roll centre, which compensates for the flattened LCA when lowering.
My understanding of bump steer is that the difference in travel path of the strut and steering system causes the wheels to change toe throughout the travel range (in jounce or droop).
As the outer LCA ball joint to steering arm displacement has not been altered it shouldn't change the bump steer properties (the ball joint still attaches directly to the steering arm, which is then spaced from the strut tube/spindle).
In some cases however the resulting toe change over the full travel range is not linear (Can look parabolic), so thinking out loud, the spacer could change the location of your datum (i.e 0 point) along the parabolic curve which would then have an impact on the overall toe change through the range of suspension travel (maybe)?

Or have I just proved that they are in fact bump steer spacers? my head hurts now, hehe.

this is a link to a discution on bump steer http://forums.hybridz.org/index.php/top ... steer-faq/ i personaly find the subject boring

mmm boring?

It is one of the most important factors in a good handling car.

from the description even within the sellers post, it would appear to confirm what I was talking about.
They are really bump steer spaces in name not function.

If you don't move the inner/outer tie rod or LCA pivot point (with respects to each other) it should not effect bump steer. In the case of the spacers, which still hold the LCA and steering the same as factory, besides what I was discussing above about the Datum point change, I can't see it having an adventagous change to bump steer.

These are still very useful for lowered cars, in that the instant roll centre is kept at a reasonable height and in the worst case stops it from going below ground height.
