And I'd run the numbers before purchasing the 4.09 ring & pinion- the power peak on the Ecoboost engine is only at 5,500 rpm. First gear is so deep, that you'd have a pretty steep launch ratio even with the stock gearing. And turbo engines tend to be more tolerant of taller gearing anyway.

I would use the stronger half shafts regardless. Especially using slicks and shocking the rear end at the launch. With the stiffer gear and it shifting into over drive I would think the 4.09 gear should work fine.
