Default C8 chassis assembly

Hey FVS. Do you think you can use your skills to assemble these pieces? There are two magnesium sub frames. B. They are connected to 2 hydroformed perimeter box sections J and and one carbon fiber backbone. K and P. There is a front and rear bulkhead assemblies attached to these sub frames. EDGMNH and more, which also encloses the perimeter box sections. If you can use your eagle eyes to make some suggestions, I may be able to draw the whole chassis even in an exploded view. There seems to be enough info here except for the rear structure to do the job.

The yellow circles are suspension hard points. 1 is in the front mag casting and maybe 2 also.




I can't see where the suspension hard points are here. They may be above the sections shown at the B arrows both front and rear.




Front left Lower A arm attached at 2



Rear Upper control arm attached at 4 which is in the rear bulkhead/ body structure assy. This yellow line is parallel to the bottom of the chassis. The brake rotor doesn't seem to be at the correct angle. I would be really interested to know if the spring is loaded. The position of the A arm in this case would help with an issue I am having with the geometry. IE: Neg. camber in droop.
Also, can you see where the bulkhead/body structure and the subframe come together in this picture? Your rear wing actuator is also attached in this location.


7 would be where the subframe is attached to the body. Notice Anti squat geometry of the A arm. 3?


Notice the anti dive geometry in the front upper A arm?




The 560 HP LT7, Can you see how this engine fits on the cradle/subframe below?

That is some piece of work Shaka. I think you have this whole thing put together in your head already!
Great job br asking down the pieces and figuring out a lot of the engineering.

I will I’ll need to digest this a bit and see if I can do anything to help.

Great post to read thru!
