aaron is right, my 2 gts are tough as nails because of the parts I added to them.
rpm arm mounts, alloy rear bulkhead, trinity one piece motor mount and tranny brace, titainium hinge pins and tie rods, rpm ball cups, doubled up shock towers, not to mention all the washers and lock nuts under every screw.
The local guys' ad2's are all bone stock and they have survived horrendous crashes without any problems.
