As for cornering..although I only got to drive it for one day before it snowed here...it seems to improve it substantially. Because it widens the the stance..it gives it a larger surface area to distribute the weight over.
I don't think the spacers voided anything. I had the ford dealer do it while they were putting on the mud flaps and changing the rims out. I asked about that and they didn't not mention anything. I have heard from others though, that if you go over 40mm it causes extra stresses on the hub and the axel. So, that could be true. I kept it to 30mm which is ample to achieve the goal of making the rear tires flush with the fender wells.
Hope that answers your question. If you are ever coming to Laramie (in the summer), because I don't drive it in the winter, give me a ring and we can go cruzing with the other two bullitts in town.
