Try sticking with the topic at hand, and keeping your stupid comments to yourself. Phantom grips work pretty well and will make a nice difference for hooking up in the quarter mile. Being Quaife doesn't make a differential for our application, you now get involved with finding another rear differential from another car, then getting axles and modifiying them to fit our application, it becomes much more expensive plus the necessary fabricating to make it all fit correctly. Alot of time and money when a phantom grip will more then likely do the trick.
