The car wanders, but there is *zero* feedback in the wheel... it's like the wheels are following the road, but there's so much slop in the bushings that the car stays straight until the bushings load up enough to move the car just a tiny bit.

Also, it doesn't feel like it's wandering because the front tires are turing, it feels more like the entire car moves latterally about a quarter inch or so.

But yes, the offset is significantly different and has pushed the centerline of the tire away from the stock location. We'll see how the rear bearings do.
