Ill grab a tuner Aaron. No im not an engineer and yes I will be very upset if the car is written off and I am not paid out. I also said in an earlier post" this was only my opinion". I can understand the windscreen bit, just like the rear seat in sedans is also structural.What you say is correct, you got me on technicalities. If you hit the support bar with a 2kg hammer it will go through the support bar. The falcon weighs 1700kg + crew. So 30,000Nm(1800kg at 60kmhr). A 2kg sledge hammer would hit with about 30Nm of force.
The bar supports the standard cooler doesn't it? I have only done my car and I can't remember.
