April 22, 2013 - Short test session.
The new tall wing mounts were wobblier than I liked. Pulling back hard on the wing also showed a bit of bowing in the lower section. I looked at a few ways to fix it and decided to try guy wires. Excellent result, it's stronger both laterally and longitudinally. The lower guy wire points are right where the greatest deformation was when I yanked on the wing, and the whole assembly is solid. The fact that the wing attaches to the uprights with a big plate helps as well.
On Saturday, I took the car out to Grand Junction Motor Speedway to test it out. And I only got in one session. The track was cold and the car was pushing around, but more importantly I could hear a thumping from the rear when accelerating out of left turns. It appears the new axles might have a bad CV joint, I'll dig into it later today. I have to get it fixed by tomorrow night!
