I cannot believe my '08 SRT8 comes with a single spinner, not even an LSD!! how **** is that? you pay $80k+ for what is potentially a race car, and it doesn't even have LSD!! my guess is it has something to do with the ESP, an LSD would be trying to force two wheels to spin and the ESP would be trying to stop both wheels from spinning rather than controlling the single wheel spinning and shifting the power to the non spinning wheel... my plan, tell me if it cannot work, is to put an air or magnetic locker (like those used in off road 4x4 applications) into the diff and wire the activator (the relay to apply the locker) to the ESP off light. this would mean the diff would be single spinner while the ESP light is off (the ESP is functioning) but when you turn the ESP off (the little light is on) the diff would be locked solid... this way, whenever you wanna do a demo, or you are at the track, you turn the esp off, the diff locks and away you go!! sound feasible?? anyone had an experience with this sort of stuff before? anyone know how to go about it, especially wirting into the ESP light?
