Thanks guys for the great feedback. I think that I will make adjustable rosejoint or bushed lower control arms.

 

Will this effect my steering?

if your talking bump steer or something bad like that then no, well assuming you redo your toe of course

i was after more camber myself. went to a suspension place. they told me to go to pedders caus they supply special bolts that give that negative camber when put in. havent done it yet but give it a try. hope it works out

i'd just redrill the crossmember mounting holes further out, then you can always change back, don't forget to widen the rear track when you widen the front to keep the car balanced

 

as a rough guide every 10mm you move will net you about 1 degree of change
