Looks like tire size is the answer! The fronts are 245/45-17 and the backs are 295/35-18. If my calculations are correct, my front is 25.7" tall and the backs are 26.1" tall. That's a .4" difference is all were new. Looks like the backs wore a little and make the traction control kick on. Need to go with a taller rear tire to get rid of it or ignore it until I am ready. Thanks!
Do the symptoms go away above 70mph? Or is this an isolated speed at which it occurs? if it happens at every speed greater than or equal to 70, maybe the tires could be the answer, but you say 70 as if it is specific.
I would look at the sensor itself just to rule that out though.

I would be skeptical to think this is the final answer. 295/35 is not very different from the stock 275/40.

You could also reduce your front tire diameter. It looks like you are running stock C5 tire size on the front and stock C5Z tire size on the rear.
