I have to say something now about this bar; It ain't gonna' do a whole =
hell of a lot. It's way too long for it's diameter...too much flex. =
The crossmember you are trying to reinforce is MUCH stiffer than the =
"reinforcement", consequently the stock crossmember is still going to =
absorb 99% of the stress. If you want to stock the cracking, weld a =
large, thick, form-fitted steel plate to the crossmember. This will =
spread out those stresses. The trick reinforcing bar is way too =
flexible to transmit the vertical stresses to the sides.
That's all...

Subject: Front crossmember stress bar
Hello all!
Alot of people have been working on this I know...and one bolt =
together bar is in testing.
However, I now have a prototype of a fully welded bar...more tweeking =
continues. It will be FULLY bolt in.
Work continues this week, should have a ready to bolt in bar to test =
on ALL of my A1 chassis vehicles (see my sig...only A1 chassis I am =
missing is a Mk1 Jetta).
Price *should* be $100 plus shipping, fully welded, 3/16s steel (box =
and plate steel used..the box steel has 3/16s walls and is inch square =
outer diameter (IE, strong as hell). However, the plate steel will =
allow for side flex to not load the front motor mount with cornering =
forces...this bar is designed to control upward movement ONLY). Bar =
will come bare or primed based on request. Powder coating, and other =
options will be available for higher cost.
Here are pics (again, this is a very very rough prototype):
http://www.vintagewatercooleds.com/~blklace/BAR/
Please let me know if you are interested...and general feelings of its =
construction. Realize, I am attempting to make a universal bar for all =
A1 chassis, hence some compromises were made in its design. =20
(and damn are there alot of little annoying differences on A1 chassis =
cars throughout the years)
I am fully confident that it will not allow the crossmember to flex =
upward at all however, no matter what A1 chassis it is bolted to.
