Somewhere on here there's a thread about Coupe roll cages

Yes I did make it.
No plans as such - I did some initial drawings, but then bent the tubes to fit the car.
As Tim says there are a couple of threads about cages. Here: http://www.gtmdrivers.com/forum/roll-cage-and-competition-prep-t367.html and
