Thanks for the interest! But yep, I've decided, reluctantly, to scrap the project. I really did want to complete it and compete with it, but for reasons which I can't really go into here, I decided it'd be best to quit it.
Again, thanks for all the interest and compliments, they really mean a lot. Perhaps I'll have another crack at a speed record car in the future.
good luck..im also shooting for a world record in MT class...im designing a similar underbody component ( like F1 racing) that enables downforce on the chassis..my platform is a heavily modded 3905 EMAXX..much heavier than your setup- so im utlizing brute force as my main design feature!
