    Hi MI906 (whoever you are...)

    I woudln't worry too much about modeling these bushing stiffnesses in an FSAE car. The only reason they're there is to "dampen" the whole system since the bodies used...

    Hi Rodrigo,

    getting back to the original topic:

    So, just speculating here, maybe some cars "had to be disqualified" in order to push some other cars up the rankings? I feel a conspiracy theory developing ;-)

    Simple solution: Don't have dimensions relative to moveable/changeable components in the rules. Have a template that is essentially a plywood cutout. If you can fit your wing through it, ok, if not,...

    Claude, I am afraid to say that but I think I disagree with your statement of your uprights still being too heavy because they didn't break.

    An Upright is a stiffness driven component. So the...

    Claude, I don't really understand (ünderstand? :D ) why you're going on about the impact attenuator. It's in the rules, appendix T-3: Standard Impact Attenuator. It is in there because the SAE wanted...

    Does the standard loom and ECU have a sidestand sensor? Usually, motorbikes cannot be started while the side stand is still out, and they have a sensor to detect that. If there is a place for it on...

    You may have forgotten to add the driver weight, 220kg seems a bit optimistic for a first year, 4cylinder, spaceframed car on 13" tires, and I think you might have forgotten to factor the driver into...
