It is far easier,and quicker, to modify the top wishbones. Extend the hole that the front upright bush bolt goes through 10mm IN. You then weld a washer on the OUTER sides of the top wishbones, to reinforce the new hole, and if you are sensible, back-fill (with weld) the old hole---clean everything up with a powerfile and you end up with top wishbones that will give you just about zero camber (which is what you want for road use). You might still have to play around with camber shims to get to the correct figure. Toe-in is, again, best set at zero---the important detail is to make sure that your track-rods are EXACTLY the same length--if they are of different lengths you will bugger up the "Ackerman effect".
