My installer was in contact with H&R because had an X5 with the same springs and he said it was smooth compared to mine the numbers are for the 1.2kit I don't have them off hand but we checked the box and springs themselves. H&R claimed the diesel will sit lower than the 4.8 must be heavier maybe iron block vs aluminum I am not sure I haven't really looked into it much.
