Finally drove the car back today after the new batch of work including re making the wheel arch supports out of solid bar instead of tube, lowered front springs, AVO adjustable shocks all round and removal of a leaf from the rear spring as well as a slightly lengthened main leaf.
it felt ok, much softer ride than before, the camber still looks way out, but I suppose it will probably corner better if nothing else. and the turning circle has been reduced now due to the lowering of the front (it's missing the holes we cut now)
The only downside I can think of is that the negative camber might wear the tyres on one side quicker, and also it maybe looks a bit odd, but it's better than having to re-weld the arch supports every other time I take it out.
here's some pics - front arch support

Front now sits a bit lower which hides the lights a bit - which I like

Rear negative camber is still there and also sits a bit lower now (I know cos the exhaust scrapes now when I drive up the ramp into the garage)
