Pete, lowering the car will produce excessive camber and must be adjusted to get it back to factory spec.
You have limited adjustment on the rears and no adjustment on the front.
If your front camber is outwith the factory specifications then you will have to replace the front top arms with adjustable ones.
If there is insufficient adjustment on the rear camber snail cams then you will have to fit adjustable arms mate.
All these adjustable arms and toe bolts can be found in my sub forum/zed store, just click on my signature picture.
As usual, all in stock and good to go same/next day
