MUSHROOM ADAPTER POSITION?
CAN anyone tell me which position they should be fitted in the hub? ie where the hole should be.

well people put the offset hole where ever it gives them the desired camber, for starters I just have the wheels at zero and then work from there once
on the road.
I sure others will say something totally different...

Mine are set with the hole in the mushroom adapter at the front.
I believe this is generally what is suggested.

When you look at the upright from the side you would like a line through the joints to go through or as close as possible to, the center of the hub.

I was at mk today and asked them the same question ,i was told to have the hole towards the front then make the camber adjustment,was told to set it
neutral to start with.

The mushroom is not for setting camber, it's for setting caster. Once you have the desired caster (which is usually 'as much as
possible', ie hole to the front) then you adjust the camber using the upper balljoint.

Rotating the mushroom doesn't change the castor as the king pin angle is still down through the ball joints (and castor is the KPI as viewed
from the side) - It does give an effect called trailing hub (like supermarket trolley wheels) which gives slightly better self centring and more
resistance to turning.
Best to have a play and if you want to get it bang on then go and find a garage that can do race setups like the Procomps of this world (Matt, If you
are reading, I will get to see you soon, promise!).

In my opinion this is false.
The centre of the hubs hole (strut) wont be anymore inline with the centre of the arms/bracket, it will lean backwards...
its true that the balljoints don't move any degree.. but the effect is clear, the wheel axle will travel a line wich is not level anymore to the
ground...

Scrub radius changes with trailing hub so it will have an impact on self centring and hence resistance to turning but the castor angle is set by the
ball joints so it won't change by altering the mushroom.
Think we're saying the same thing but there are some serious suspension geometry experts on here so worth a report to catch them IMHO
