I'd be interested in knowing this, too. Given what Ford pays Multimatic for those wings, they must work because it's a meaningful percentage of the Base/R price delta (if rumors are to be believed). In fact, considering the R-specific development costs for DSC, ABS, and the aero, as well as the hardware costs associated with the wing and wheels, I'm pretty sure they are losing money (relatively) on the R. I am NOT complaining, mind you. ;-)No. I'm just stating Ford ran the 350R prior to developing the current R spoiler and after at the same track. One with one without.
What numbers did Ford get?
