You can get the tow hook that is mounted under down low on the nose just above the splitter. I am having a tow hook accessible from the upper air inlet. I am modifying the upper air inlet extending it forward and squaring its appearance. I want the air inlet to carry a little more of the square appearance like the lower body has. While it will not be as aerodynamic, it will be more forward which will actually allow for more air (according to Fran). I intend to track the car some, and he felt an upper tow hook might be better...
As far as the seat brackets- there are other threads that have referred to them, but there are brackets that will allow seats to have some adjustability. To be honest, I don't know all of the details about it, except that when we visited Frans, my wife said she too would want to drive the car. Without this, she simply could see. so, he felt we needed this option. Maybe someone can comment that knows these details...
The "Fling Wing" was a request I had made that Fran said he had already considered. My self and my wife prefer the street tail that has a longer extension of the rear body behind the rear wheels, and it covers all of the back of the car. The race tail is open in the back for the diffuser. The advantage of the race tail is that you can have the rear wing (which I wanted). So, I wanted to find a way to have the street tail with a rear wing. This has not been possible before because the rear wing would prohibit the street tail from opening. So, Fran is developing a third option. The street tail will have new uprights made for the race wing. It will have 4 pins that come out, and the wing is removed, and the street tail can then open. Thus, the "Fling Wing". It is going to be an option for other cars too. I have seen a wing mounted on the street tail body, but considering the wing will have 1000 pounds of downforce on track, a connection to the frame seemed better. This is a good solution.
I have 3 other options that are skunk works for now that I can't wait to share with you.
