great thread i'll be making my own here soon

Bump for some great custom fab work!

I've only skimmed the posts in this thread, so please excuse any redundancy here.

I'm thinking that in a hard corner, the inside rear wheel is airborn, and need not apply.
Focusing on the outside rear wheel, you'd have forces trying to bend the trailing arm inwards
(toe out), and forces trying to tip the top of the wheel outwards. (positive camber)
Toe out, would kinda be like four wheel steering, helping the car to make the corner. In my book, (and i'm thinking autocrossing, and road courses, NOT Rallye) this would be a good thing.
I suspect that the second case, twisting the trailing arm so the wheel gains positive camber, is the lesser of the two. Based solely on the moment arm (trying to sound smart here) of the first case being longer than the second case, and, in the first case, you're bending a T section (in MKI) where the arm meets the lateral beam which would be significantly easier than twisting a tube the diameter and wall thickness of the trailing arm.
Regardless, even if you gain positive camber on the outside rear wheel, perhaps lifting some of the inner tread patch off the pavement, would this not also serve to help the rear end around come around and to some degree eliminate the natural understeering tendancy?

Thoughts?

Great thread, BTW

still making mine!I have a rear beam,just gotta go pull it one slow day!

[Daskoupe]

bumping for actually starting mine...

[Daskoupe]

i was dragging ass lol

Got these boys ready for some tig welding tomorrow.Towers gonna get done tuesday

[Eganx]

Keep us updated.....I was interested in doing this a while back and never got around to it....

[franz]

it is a shame looking at all of these that everyone is missing a very simple concept when trying to reproduce this...

and this was orignially a Bill Scott Racing piece used in the early 80's in SCCA... i simply changed the design to work with a later trailing arm where the beam was no longer located at the pivot.

If its a shame then why don't you offer up this concept Mr. smug.

towers are cut..

Do you mind sharing what you are talking about? Not really following what you are talking about, we're going to keep reinventing the wheel till we know about what was done in the past.

What an enlightening post.

Regardless, it was a fun project for me when I was fresh out of school and itching to fab something up. And as a bonus, I enjoy how it makes my car feel on the road, all that matters to me.

This thread is full of people i though where dead and gone.

My towers are done!should install all parts on to the beam this weekend I'm stoked

[Eganx]

Where are the pics?

[Daskoupe]

pre paint

[Eganx]

nice.....are those 3/4" hiems?

[Daskoupe]

Well I got them on



But It hits the gas tank Thinking about making new towers that are 2 inches taller.



How low are your cars? I'm not against raising it more if I have to

[Brian.G]

You should have put the rose joints in centre of beam in double shear.

But, other than that, looks good, apart from tank issue

Brian,

Brian,

Thanks I got the car up like an inch threads from that pic still hits. I think I need like another 2 inches. So I am building taller towers instead
