I'm looking at lifting my d40 about 2" but I'm not sure what brand I should go with. I don't want it to affect the ride on the road, I don't want it to be stiff and uncomfortable. I can get the tough dog lift kit for $1100 or I can get something like the old man emu kit for $2200. Is it worth the extra money or it the tough dog kit just as good. Does anyone have any experience with these kits.
