where can i get bump steer spacers for 200b/stanza struts for my 1200.

at a half decent price too.

Wats going on Mick why u need these??

These are used if you lower the suspension, arn't they?

I'm asuming that they lower the tierod arm to stop it from hitting the body/chasie

they are used to put some angle back into the LCA. as a result of installing super short struts. Remember that the LCA moves in an arc rather than just up and down. Ideally you dont want your LCA's to go past horizontal at full bump.

why exactly is that? whats the actuall theory behind it?

i know it changes all your suspention geometry and such, but why is it actually so bad for it to go past horizontal?

is it just that the angle between the LCA and the tierod changes to much or are there other reasons?

and mik...why do you need them?

because when you go over a bump, the car auto-steers to one side or the other.

hmmm,
My understanding of bump steer is when the inner/outer steering tie rods do not follow the same arc as the lower control arm for a Mcpherson strut. I.e in bump the diffence in lower control arm arc to streering arc causes a steering input.

The "bumpsteer spacers" i have seen (eg maddat) that go between the lower control arm and strut (i.e space the strut further away from the steering arm and ball joint/lower control arm but do not change the spacing of the steering arm to lower control arm), in theory (and I could be wrong) don't change the arc path of either the lower control arm or steering tie rods in isolation, therefor do not effect bump steer.

This type of spacer will have an effect on the Roll centre by raising it up (closer to CoG - as stated by Benny).
When the LCA moves past horizontal it has a changing effect to the wheel camber, i.e during compression you get an increase in neg camber unitl horizontal then past that point the camber starts to decrease (tend back towards 0).
I will have another look at "race car vehicle dynamics" tonight to confirm.

As for the original question if there is a problem with Bump steer you need to change to LCA to steering arm arc either by changing the length of the LCA, moving the inner LCA mounting point or the steering arm inner tie rod mounting point or changing the outer steering tie rod location (ie new steering arm geometry).
