Nice job!!!

They were extremely cool about my design. I showed them what I liked and why I liked it and asked for feedback on the design, and they liked it as well. They gave me some advice on how to make it just a bit strong. They incorporated they're own knowledge of this sort of thing while still sticking mostly to my design. Ill take some pics of it today since I have the call back.
So the rear floor is kind of like 2 skins in that area, a bottom skin which is where the rear subframe bolt receiving threads are and an upper skin. From what I can tell in the pictures, it looks like mainly the upper skin/trunk skin is being reinforced. But yeah, based on the types of failures you had, I agree that the structure you had built is better than the Mason bar.

I'm interested in seeing it!

How does the car feel now?
