Ken, the one I suggested earlier http://www.acroname.com/robotics/parts/gp2y0a21yk_e.pdf... well, I just read the timing chart on page 4, and believe it or not, this infra red sensor is slower than your sonar! But, the good part is, you wouldn't have to wait for one to finish, before sensing the other. It would be nice to find a faster response sensor, if possible though, to allow your car to measure under 20 ms (at least for the side).
