unless you lower your car more than 3 inches with a body kit you can fit any jack under the car, you can crawl under if you wanted. i have to put my stock jack under there and raise it about an inch before i can fit my hydraulic jack under there and raise it the rest of the way. at shops, its their problem to deal with, if they crack the kit, guess who pays for it? if they dont want to take the risk then you just take off the front bumper, its the only one that hits. and this takes me less than one minute to remove whenever i do it
