Finally found the thread and it was right under my nose. When the pictures were taken I had just finished testing the car so it was pretty dirty but at least you can see most of the mods.

Since those pictures were taken I have redisgned the rear spring setup to be similar to the front. The single rear spring setup pictured allowed too much body roll and caused the car to push in the corners.
