I am also considoring this. Alex do you suplly top wishbone kits and toe and camber bolt kits? If not where could I get them from.
Thanks
Your best bet for the above is one of the Traders on here. Start with CS or Envy but there are others.
The answer to your other question is that the stock zed does not have a facility to adjust the camber on the front, so adjustable ball joints must be fitted to allow adjusting the camber back to oem settings. Toe is not an issue on the front.
On the rear there is limited adjustment for the camber with the oem snail cams, so larger bolts are fitted to help solve this issue. If the new camber and toe bolts do not do the trick then adjustable arms will have to be fitted.
