Weakest area of the longs/Flex point, Searched but came up empty Options

[drive-ability]

I know I read some where on the forum about a certain area of the longs where it seems to flex more. I just can't seam to find the Picture/information. Can anyone show me where that area is?

I don't have any sag problems but since I have a V-8 my feeling is to go with a cage. This is a street car, so I may only tie in the rear shock tower for now.

"supposedly if you took a plumb-bob and went from the top of the windshield frame where it meets the targa top (middle of the car) and go straight down, that is roughly the spot....I was thinking you could lay on some spackling or something simliar, let it dry on the longs and do some quick and dirty tests to see where it cracks the most"

I did look where that spot, it looks like a thin transitional area. The use sparkle is a good idea. I want to give this car a little more structure.


JP,
Nice work, that cars not going to sag (IMG:style_emoticons/default/biggrin.gif)

I'm curious how are you going to tie into the rear shock towers on a street car? I'm thinking you have to go with bars thru the rear window? How do you maintain water intrusion protection? Trying to learn more. Thanks

First off, the rear window seldom gets wet....as I recall from the days I had one & went out in the rain.(IMG:style_emoticons/default/biggrin.gif)

A guy with a few fab skills could use a plexiglass rear window to seal it off......prolly not air tight, but close enuff.

The Engman kit stiffens the box structure around the passenger compartment....the front & rear box sections still flop around independently.

Draw your self a little picture that represents the 3 box structure of the 914 chassis or just look at the car with the doors off.
A tall box at either end joined by a long shallow box in between. The suspension is near the extreme ends of the tall boxes and where force is applied to the chassis.
Once you've done that, it's easy to see the weak points are and what needs to done to fix it. Simple to see, tough to fix. As I see it, it ain't worth the trouble for a street car.
