can some clarify the reason for and explain the procedure of deleting the crinles at the end of the frame, and making a crossmember?
p.s. sorry for posting on such an old thread...
The reason for deleting/reinforcing the crumple zone is the mistaken belief it isn't strong enough. As some on here have shown it is more than strong enough. The only benefit on modifying the frame horns is it would give straight surface to make mounts on.
The cross member is so the frame horns don't twist. With the coil set up the engine x-member takes care of it. The leaf mount is too far past the engine x-member for it keep any sort of rigidity in the frame.
