Moving front spring eyes rearward

Quick and dirty calculations on my car shows i lost about 12 lbs on the rear wheels from the axle relocation, about .85%. Removing 40 lbs from the front, adding 60 to the rear, i figure compensated. And so did the difference in tire contact patch, from 26" tall tire to 29.
And besides, it just looks so much better.
Do you really think traction will be much worse at 117" than 116"?
