Steel or fibreglass bonnet??!!

[Sandman]

They only bow if they're crap fibreglass or the factory struts are retained. Weaker struts are required as they are not supporting the force required for a metal bonnet.

Yeah factory strut particularly if new will bend most fibreglass bonnets...you'll need to find old fubar'd set with that struggle to lift steel bonnet or carry broom stick to hold bonnet up.

Hate the look of bonnet stands vs gas struts otherwise I'd have fibreglass or carbon fibre bonnets fitted for weight saving.

Blisscustom sell struts for their hinges that suit steel or fibreglass bonnets but never seen anything to suit commodores yet

not sure what you mob are on about.

my car has a fibreglass bonnet that was fitted by the previous owner - also has factory struts. I've owned the car for more than 5 years.

Never had an issue with it.

If you haven’t had an issue then they’re rooted factory struts.

I certainly wouldn’t be replacing guards with fibreglass.. guards are part of your crumple zone - many bolt on Panels are!

That's good to know and is exactly the kind of feedback I've been looking for

Just my 2c... I had a fibreglass bonnet on my VT. When I T-boned an old guy in a 1980-ish hilux with no headlights on in a 70 zone, his tray ripped everything forward of the front wheels off. The bonnet, which was ADR approved, frisbee'd off a VERY good distance onto the footpath some ways ahead. The bonnet was largely intact save a few edges bashed away and hinge mounts ripped off. It always made me wonder what would have happened if it was head-on crash, if I would have been decapitated? Never seen a steel one act that way

no they were replaced and are almost new and are the same ones as what's on my Clubsport. Who said anything about guards!?

That particular comment wasn’t aimed at you.

I'm not a particular fan of fibre glass. If you're building a race car fair enough but if you like your car looking nice stick with a stock one.

Fibre glass is ripply as anything unless the guy who made it polyestered the hell out of it and blocked it down for ages. Also get a bit of heat into it with a buff or something and the fibres start showing through.

Being a truck painter for years and dealing with allot of fibre glass I can tell you it will always crack eventually. Especially in high stress areas like where the hinges are when you lift it up and down. Star cracks will happen too if it gets hit by something. And on older cars like h series Holden's you need special hinges because if you use the factory ones it will snap.

I would never put one on any of my cars but that's just me personally. Still fix fibre glass all the time at work don't wanna be doing it at home too lol.

Yeah fibre composites are very stiff but also very brittle. The only place I'd use it is where you can't get steel reproduction panels or you're making something one off, like a custom airbox for example.
