Thanks Weasel
you been a such great help as always,

my 4.8is has 4 wheel air suspension.

i called the guy ask him the same you explained above he said yes i am going to change the position of the sensors thats all (is it safe to do? what about gt1?) yes i have made custom brackets which are adjustable thats why i am charging you $100 and yes it can be done by gt1 i can do it for you but it will drop it by 3 to 4 inches you may not like sitting too low and ride quality will be poor and air springs wont last too long.

and yes he is a bmw tech wont allow me to post his name or contact info but he may be reading this as a member lol
