TOTAL Failure at the front wing wheels. As I was trying to put her in the trailer yesterday I heard a terrible noise and she got stopped in her tracks. So I backed up and got out to go see what damage I had done. The end plates had contacted the ramp and didn't like the hinge or the plywood on the ramp. No damages to anything just a lot of noise. Apparently the wheels need to be much ferrthur forward, a little more than an inch. Apparently the end plates don't like to be pushed around. Pics after daylight.
I’ve wanted to say this ever since I read about your idea of the retractable wing. I was hoping I was wrong, but this incident has me concerned.
I’d look really hard at what that wing might do at speed if/when getting hung up. It’ll lift the car and fold underneath causing all sorts of havoc to the car, you, and most likely bystanders. I think the test on the plywood should be a wake up call that anything taller than the wheel clearance will be an issue. As autocross locations become more difficult to find, the quality of road decreases.
I’ve seen cracks and transitions in pavement at several local events that appear to be taller than the skid clearance you have.
Perhaps a modified bottom plate shape might help the end plates be more like a skid vs a hang up point. I also keep thinking about that plastic material they use to easily slide furniture around maybe some sort of adaptor, that can be swapped out as it grinds down... they have lip protectors for modern super cars that operate on same principle.
sorry rant over, I saw your problem before it occurred and didn’t say anything, I just want to offer my thoughts in case of building a better mousetrap.
Ok I’ll shut up and watch silently now...
