HELP! E39 Touring

[E39HoR]

soo, i just bought a 99 540it, and i want to dump it really low. it has an air ride suspension, i know i can go to the dealer to lower the air bags. but i need it low and stiff. if you guys know what i need that would be awsome. Thanks

You can buy some coilovers for the front and trick the bags in the back with shorter level sensor arm.

it has factory air suspension? never heard of that before?! thats awesome!
get some stiffer shocks or add secondary springs if thats possible on your car.
