Chassis stiffening - clarifications please, chassis stiffening questions Options

[TAV]

Hi everyone

I'me very new to the 914 world. I've bought myself a 914 that I have yet to get back to Australia. It has no engine, but I do have a rebuilt 3.0 from a 911sc that will I'll be using for this project.

It'll be a weekend car and 2-3 track days (solo) per month.

I've done a fair bit of reading into the chassis stiffening options, but some of the threads/resources date back to early 2000's so not sure if there's been any advances in this?

From my reading the options seem to be:
1) cage - of various designs and contact points
2) longitudinals:
a) inner - eg Mad dog and I note Engman has been mentioned, but can't find a site for Engman
b) outer - restoration design and Brad Mayeur
3) GT chassis stiffening kits
4) Tangerine "rear pickup points reinforcing kit"

Am I missing anything?

During my reading, some people mentioned that the GT kit was ineffective, but I wasn't sure whether this was in relation to the all "GT" list or to one particular GT kit
Can anyone clarify this for me, please?

The Tangerine kit (to me) seems like a strengthening kit, but I wasn't sure if this also offered and increase in torsional rigidity?

I'm aiming to stiffen the chassis as much as I can for my purposes s mentioned above, whilst avoiding unnecessary weight increase.

Thanks in advance

Ditto on both points - welcome and congrats on your new 'second job'! These things are a lot of fun. Chris Foley is the go-to resource for 914 tub/chassis expertise and parts.

I would be glad to share more about what was done on my car, which is pretty extensive (including some Foley/Tangerine parts), but not to say it's perfect or the only possible config. I have a build thread here:

Feel free to PM w/ any questions!

BTW - I believe a 73 2.0 Ravenna green car I sold in the early 2000's ended-up in Australia somewhere. It was a very clean California car, LHD, and I figure there can't possibly be very many bright green 914s down under. If you happen to hear about it or see it, I sure would love to hear an update and get the new owner onto the World.
