Seats aren't going to get much lower, there's about 2" of space between the seat bottom and the floor. Even if you dropped the seat to the absolute floor, it wouldn't help you. The problem is the leg length. You have to do what tall people have always done in smaller cars: push the seats back to the max, and adjust the angle of the seatback until it's relatively comfortable. Also, tilt the steering wheel up and out so that it doesn't hit your knees. Good luck!
