My 3 Door is currently at Calsport while Craig works his magic on my shell (full resto thread to follow once all work is done)
But I thought i'd show the triangulated rear strut brace he's made up for me out of Stainless Steels looks great and should work even better.
He's welded in a large plate with M10 bosses so can be removed if nessesary as well as strengthing it through to the diff mounting point.
Sorry for the low quality photo's they're off my iPhone:
