As Syleng1 and the other guys has said. at the end of the day, no one gets under the car and looks unless you have being judged on a concourse. So the better question is what are you doing with the car.. Is the 489 the best out of the 741,742,489 cases, some say so. Is the 489 more of a pain to setup if you don't put in a crush sleeve eliminator? Yes. Are you pushing more than about 600hp/TQ at the tire? if so you should be looking at a S60 or the like. 741/742/489 run them....
