Dave,
I did a rear tower and wing mount in one crash, and a rear wishbone.
The original plastic is not the best but aero are sending out new parts to those with the car, (good job aero)
The shock towers do seem weak in places but im not sure if that was the cork floor as much as anything, i also tool the ends off the screws on the shock towers so they couldnt dig into the cork.
I am thinking of having some 4mm towers made. If anyone else is interested let me know.
Once we have sorted the reliability, the car will be very fast. Afterall, it is still a very new car and we seem to be ironing out the creases, but it will help us learn the car inside out
