Have perused the various flip bonnet mod threads and there have been various different gas struts used – but none of the threads give the specs – can anyone tell me what they used please??

Has anyone had any problems with the struts stressing the fibreglass??

I used these http://www.strutsdirect.co.uk/components/stainless...
and S&D continue to use them.... Can't remember exact spec. (SDSS-01 400Nm IIRC)and not easy to look at the car at the moment (it's put away for winter) but will find out if you can not work it out.
S&D put metal brackets to reinforce sides of the bonnet, variable pressure struts used so gas released to get minimum force to support the bonnet.
I also put one on my inspection bonnet and replaced the boot struts. The boot ones need to be strong... mine were OK until I parked on the hill at Chatsworth and the boot would not stay up, so had to replace with 650Nm ones (IIRC).

Thanks Glow worm - can you remember which stroke was used? there is a choice in this spec of 60, 100, 150 and 200!!!

RP do the mode. Talk with Russ or Brenden, they can probably give you the info you are after.

These are the ones i've ordered for mine:

GSV6-200 Adjustable Force Gas Strut http://www.sgs-engineering.com/gas-struts/range/ad... so it's a starting length of 250mm, with a stroke of 200mm.

It also depends where you're planning to put them. I'm going to use the same location as seen here as I didn't want the strut to feel like it was in the way if I was doing any work in the engine bay.


Equally, I believe the S&D solution mounts them on top of the wheel arch and further up the bonnetwhich might give a little more stability if you have the bonnet raised.


Dimensions look pretty similar so a 250mm/450mm strut should be fine. As stated it needs to be an adjustable one that you can let the pressure out in order to get the right movement.

Glow worm: Did S&D have to reinforce your bonnet at the point that the struts attach at the top?

Robert ... Just took my car out of the roof (See profile photo) smile..... Yes I used SDSS-01-200 with 200mm stroke , if you include the ball socket ends total length is about 480 mm.

Mounts are into the wings above the wheel arches , about 2" rear of the middle bonnet bolts (which I still use , finger tight), just to pull the bonnet down flush.



Yes ..bonnet edges reinforced with steel angle brackets ... you can see the screws on the outside.
This is photo from the inside I've just taken smile
