how much did you lower it by on the front/rear? was it 2.0/1.2 or 40/30mm?

also, what was the final cost for springs and labor? did the dealer put them on for you?

is this something they normally do for new orders?

how is the ride? is it a harshe ride? or no difference felt?

sorry for all the questions..but really interested in doing this.. and want it done right..
