How much play was there in your driveshaft? I don't have a BDR, but the problem sounds awfully familar to something I experienced on my car. When I got on it it started to get a pretty loud noise and some vibration... turned out to be worn U-Joints. With the angle of the driveshaft that these cars have (at least SPF's, but I think most all of them) and the power we put through them (especially with that monster you have under the hood) they wear out if not lubricated properly. It only cost me about 200 bucks to have new ones put on and properly set up. I hope thats all it is... or one of the other simple fixes listed above.... nothing worse than you child being sick and you cant do anything for them...
