I found these on the net and besides subframeconnectors and torqueboxes I didn't knew a way to reinforce the rear.







Because I'm in the middle of rebuilding my Satellite, I was woundering if there are any other rear reinforcements?

1. I don't debate that the added gussett adds something
2. I do question why reinforcement is needed in that location

3. I also wonder what other areas have already been reinforced that then requires some added stiffness at this location.

4. Without knowing more then pictured here, IMO this is just chasing your tail modifications

5. In most situations, there is very little vehicle mass this far rearward, the leafs being so far forward biased transmit much smaller forces at this location to the chassis this far rearward, horizontally and vertically.

6. A simple panhard bar would remove much of the original horizontal forces at this location

Never knew about the panhard bar. Lesson learned.

I agree on the forces this far to the rear are limited.

Before the ad disappears:

1970 PLYMOUTH HEMI Road Runner Clone - $51000 (Oconomowoc)

This a real Roadrunner, 383, 4 speed post car. Started out as a rust free Arizona vehichle. Car was assembled over the past three years and wherever original parts could be used they were. Short of the headers this car appears like a 70 Hemi car. The person who built this Hemi has been building and racing them for 30 years. 528 cu inch 600HP Hemi @ 5800 RPM on the break in dyno. The body was media blasted to bare steel, HEMI specific torque boxes and rear leaf spring reinforcement plates were installed, light body work and painted top, bottom inside and out with Dupont Chroma base and clear. Some would say the paint is a 10 but I am very picky and give it a 9.
The fit and finish are very nice and when you stop attracts all kinds of attention. Driving this car is a pure pleasure. On the highway the interior is relatively quiet with no exhaust drone. Shifts smoothly and will smoke the tires whenever you wish. Brakes are power and work better than any Mopar I have ever driven from this era.

Looking at those pics, I wonder if the plates have anything to do with an old trailer hitch? Remember, these used to be 'just' cars. I had a '78 wagon that had a Reese style hitch welded on (looked like you coulda drug the White House off its foundation), and it was gusseted like that at the mounting points.....

Just a wag.

Sure makes sense to me

The more boxes you make the stronger the assembly. I wonder how well boxing in a subframe connector to the rockers would improve stiffness...Tim
