I need to do something like that on my Firebird, I've flexed it back so much over 140 that the paints starting to peel and I had flex additive in it when I painted it. I've been thinking about a splitter and strut rods like the race vipers come with.
Shiro, David's in Europe and does much better with our language than I could ever possibly do with his.
