Vacuum Forming Splitter

[Chip42]

might be. the good news is that the exposed area in the front builds a lot of positive pressure on top, which could be creating moment about the forward pin, and actually negating a lot of the loading to the rear pin from whatever low pressure there is.

I think an average pressure drop underneath + front end high pressure area is producing ~150-200# on the front wheels of our little MR2s, just based on the bowing of the 3/4" hardwood plywood planks we use. we don't have good ride height change data. But there's a LOT of exposure under the beak of an MR2, so it might be a more extreme example (though most of you all are seeing 50% higher top speeds and should expect a LOT higher loading for a given shape).
EDIT:
throwing some math at it, and rough numbers for all variables, making assumptions etc... the splitter on our MR2, which has ~6in of distance from the tip to the first support bolt would take ~20psi of pressure differential to deflect the tip 0.1in.
Damn I wish I had me some CFD...
