Guys, sorry for the delay. As for putting washers under the bolts, I thought of that idea also. Actually, the two rails don't rest flat on the floor. The way it is right now, the seat is anchored only by four bolts that rest on top of little mounds. So, the way e46myway explained it, was the way i first thought it was. But, take a look under the seat and notice that the full length of the rails don't rest on the floor of the car. Putting washers under the back screws wouldn't then seem like it changes anything all that much except for the amount that the screw goes down. Getting new screws would then be of priority. I still would feel nervous doing such a thing because I am not an engineer and don't know what could possibly happen in an accident. I will have to ask the dealer and see if they can offer me anything.
