Picked the car up and trailered it home after SEMA last month, so getting ready to start digging in. First order of business was designing up a full frame chassis for the car with 2x3 .095 wall tubing and 1.75 .095 DOM for the cage. Sort of nice being an engineer and having access to analysis software; I removed about 50 lbs of triangulation that, while looked like it would matter, had little to no effect on overall rigidity.
The orange bars at the rear don't seem to make any difference but I sort of can't let them go
That main bar across there will have the transaxle mid-mount welded to it so I feel the need to tie it in better, and the fuel cell will be mounted on that "cage" as well. The gray door bars will be removable (which will be a PITA keeping 4 break points lined up perfectly) as well as the bar across the main loop for belts as I would like to have a rear seat setup if I can manage to keep the tunnel small enough with the transaxle torque tube and low stance pushing things up in the body.
At least that is the plan - those things have a way of changing
This is probably the 5th chassis design in the last month as I go out and lay under the car periodically and then search this forum for all the chassis cars to glean ideas as well. That and being an amateur always makes for "dynamic" progress.
One thing I am considering is keeping the chassis/engine/trans completely level to ground and then raking the body on it v. raking the suspension pickup points and then everything is raked relative to ground. That is why the outer rocker rails appear to run at an angle... because they do. I don't see this done with other cars so maybe I am over thinking it, wouldn't be the first time

That and I have seen comments on this forum that stating prices seems to be a no-no and will spin this thread completely out of control.
