can someone explain geometry settings to me?

[dixieflatline]

I've come across this a lot recently on here and I don't know what it means. It sounds very important though. Could someone explain it to me?

Thanks.

a2 + b2 = c2

It's shorthand for "suspension geometry".

Basically it means "all the wheels line up properly in the right direction at the same time, and touch the road at the right angle (most wheels lean inwards slightly at the top which helps go round corners) and also the front wheel balljoints are inclined backwards slightly (so that the car doesn't steer like a wonky-wheeled asda trolley with a hyperactive baboon bouncing around inside it).

Clear enough?

Full technical explanation available on request, but not while I'm supposed to be working

A quick Google came up with this:

Adjustments can be made to the suspension/steering/ball joints etc all of which alter the angles, i.e. geometry.

Rack Height (if adjustable can alter bump steer)

Nope that's good enough for me! Anything more technical would go straight over my head. How is this adjusted on the S then? I won't actually be doing any of this myself, but I'm a bit curious.
