Had much chance to drive / develop this? Looking forward to an update if you have any!
Sorry! I've been really busy at work 
I'll post photos from the 3 races. Next July 13th I'll be in a trackday with Lotus Elise, Exige, 211, Caterhams, ... Then in september another race and in october the final race in Circuit de Barcelona Catalunya, like F1!
Mechanical updates... Only some details... We have changed geometry three times and now is almost perfect. Lots of tires... 
We have to change the Stack water temperature gauge, from electrical to mechanical. We think the electrical one is showing 30ºC more and the sender is a Stack one too, so something is wrong.
Next week we will solve some braking problems. We improved the problems I had but they are not perfect yet. It's like sometimes they have air in the system but there is no air. We have changed master cylinder, rear cylinders, ... They are better but not perfect.
And we will have to change baulk rings soon. From 3rd to 2nd it crunches a lot. But I've learned how to do double clutch 
Now, the photos!
First race in Calafat (Catalonia)
