I found some steel hoods online.

Good idea!

A flash of brilliance from ol Leonardo … :thumbsup:

The panel gaps in the photo with the hood closed look off. Something is either damaged or not OEM.

I did get a good chuckle over how long it took for the magnet idea to come up.

You don’t really have to weigh the hood. Use the magnet to see if it is steel and just feel if it is light or heavy. An aluminum hood is obviously lighter than steel. If you can’t tell then lift up the hood on a friend’s car.

Still, the hood seems like it sits high enough that the strut should hold the hood in the high position at least. There is less leverage (torque) for gravity to have an effect on the struts the higher up the hood is propped.

Now we have to wait a month for the next episode of "The case of the purple hood"?

This is as bad as "Better call Saul".

Maybe the car is parked in a stiff tailwind.

Maybe OP can post wind speed and direction along with hood weight and metallurgy report. Carfax report might be good too. Need more info.

We can rule out local gravity. If anything, it works in OP's favor.

What we really need to know is the barometric pressure … since the shocks are gas filled ...or are they..??

Everyone gave up but I am still waiting 😁
Did anyone, by chance, figured out what the issue was? Maybe Grimmspeed since he was working with them.
Was really exciting to read this thread.

The last post in here is from 2018...

I am aware of it but a lot of people posting in this thread are still active on the forum.
Was just curious if someone heard anything about it [emoji3526]

my 86speed hood struts are working fine.

otherwise, i really don't know what the question was anymore

I have the same struts as OP on a '20 and they are fine.

I've had the same struts on mine for eight years. Still charged enough to keep the hood lifted. The secret to these gas struts is to not scratch the rods. They all leak down eventually. I'll replace the struts when it's time. The minimalist Grimmspeed brackets are perfect.


Edit... I just figured out, once again, that I'm full of shit. A nick in the rod isn't the killer. Duh. It's breakdown of the internal seal.

Are there really direct replacements for the Grimmspeed struts? I like their brackets but want to paint the plastic part of their struts. If there are direct cheaper replacements I would like to paint them instead of the $140 ones [emoji16]

Would be great if you can share the information if available.

Thanks

Of course there are. It's just a Stabilus Lift-o-mat. I'll cross that bridge when I need them.

Few companies reinvent the wheel only to sell it to a small market for less than $200 ea.

The real value add is in the elegant bracketry. Minimalism FTW. If I was a believer in strut tower braces, I'd choose only the Grimmspeed. All the bent ones with hinges and sheet metal doodads are bullshit. They have more give than the actual strain they are supposed to control.

Thanks for sharing the name. Any idea what length or part# I need to check for the Stabilus lift-o-mat? Are there any specs written on the Grimmspeed ones so I can check them when I order them.


Thanks again

Nope. Like I said. Mine are still serviceable.

Google is your friend:

Thanks for the link. I also found several frs/brz compatible ones. I am gonna buy the Grimmspeed ones. Just need some struts compatible with grimmspeed brackets.

Thanks

You mentioned painting them. I can't weigh in on that but you could buy a pair from your local store and try it - if nothing else just to get practice. They don't even have to fit.

No... I take back my own correction. The gas seal really is around the exposed rod. Here's how we know this. If the gas was to be compressed fully between the face of the piston and had nowhere to go, it would behave like a bicycle pump with a plugged hose. It's not a bicycle pump. It is able to collapse with only a small increase in extensive force at the collapsed position. The extensive force equals the internal pressure multiplied by the cross sectional area of the opening upon which it acts.

All the internal parts are at equilibrium. The cross sectional area to be considered is the area of the circle projected by the axial view of the rod.

I'm guessing no one cares about my ramblings here. I'm just keeping myself honest with stuff I say in general.

when in doubt, there's youtube, and a dude with zip ties and a rope..

Yup. Bottom line - don't scratch the rods.

I thought that was only on YouTube After Dark.
