I'm debating whether or not to go with the Df210 or Nf210 springs on my 2012 xB. I just picked up some XXR 530s last week, 18x8.75 33 offset with 225/40/18 tires all the way around. It looks like I have quite a bit of room to lower the car so I'm leaning toward the Df's but I do drive a lot and often carry stuff in the hatch with my rear seats down, plus I sometimes have passengers, so I don't want to rub. Any feedback? Thanks!
