The road I drive on when leaving home is fairly smooth and in the wet it becomes pretty slippery. Totally my fault because I was in a hurry and pushed it too hard, they are not real soft. They chip more than wear because of the roads I drive on. I have Champs on the front and they feel far better. Online reviews bagged the Champs saying awful in the wet and wear out in no time. But I have had mine on 12 months and they have another 12months at least left in them. Tiny bit of edge wear and feathering because I push it a bit hard on my way home but that's nothing. I read your write up about shimming the cones but I'd rather not because I have always had someone else work on my diffs. I have a mate in Adelaide who would machine it for me and be ok not doing a full rebuild, I suspect.
