Should be able to figure this out myself but.. .. If I wind the spring seats down does it make the camber more negative or positive ? Seems to me that the top of the upright stays where it is and the chassis goes down so the upright has to lean in at the top but can't decide if that is right.

Hmmmmm, I thought the camber was adjusted by moving the upright in or out where it connects to the upper wishbone.

But thinking about it as you raise the ride height the camber may go negative??

But then after setting the ride height you would have to reset the camber?

Put the car on a jack to answer the question. under the lower wishbone.

Unequal wbones are designed to maintain the geo within their normal limits. which are quite alot on the neg side. Think of how the wheel moves over a bump. can't change too much.

Simply put...(which is the way i work..smile )

Seeing makes it simple... There is an animated graphic I wrote that displays how the wishbones move - particularly the camber changes. Adjusting ride height moves the wishbones in the arcs - level lower wishbones is the simplest way to set it so that any bump/droop adds camber induced by deflection of the wishbones, otherwise you can 'lose' camber when you don't want to IMHO. If you want to change ride height without affecting the chassis dynamics tyres/wheels are probably the easiest way to do it?
