nah, they look to be the standard hinges.
the hooks are to catch the bonnet in an accident so if the hinge fails it doesnt slice through the windscreen.
the number of standard boxes you can get for the cost of building a box means you could break one a year and still be ahead after 7 years (including labour)
its dont be soft.
the 25 gtst box is tough and because it doesnt have 4wd traction the shock loading (ala 6000 and side step the clutch GTR launch) just results in wheel spin rather than damage to the gears unless you are running some seriously sticky rubber.
