Yeah Jack, I had heaps on the hinge bolts, about 15-18mm. I didn't measure the exact length of angle I used but if your good at Tetris you just feed the angle into the hole towards to front of the car until it can't go any more, mark then chop. Gives you about 200mm of angle to use that you can easily get in and out without having to unpick or cut anything else on the car. Time didn't let me weld the angle in, but will do it when time permits, carrying too much weight in bolts, Dougmo will be having kittens.
No idea how it feels, don't chuck the car around in public with all the stickers on, bad press and all that if you get caught. It has made a noticeable difference to how much the car bends when you jack it on the north/south bar. Given the amount of droop I use to get when dropping it on the axle stands, it has taken up a lot of the slop in that part of the chassis.
