Limited Slip Differential?

I got stuck in a snowbank this morning, and got to thinking that it would have been a lot easier to get out if not for the open differential. Anyone know of any LSD that will fit in the gearbox? Even one of those crappy Phantom Grips would probably be good enough for a stock 451.

As long as the ESP is engaged, you're stuck (literally.) Add something to the stock diff - I doubt it. You can try the "remove fuse 11" solution which should work.

kinda wondering why you'd be driving in a snowbank to begin with. haha

all joking aside.... you also have to remember that on top of ESP, the Smart has the ability to basically limit the amount of torque applied to the wheels in order to try to get out of a slippery situation. I'm guessing that if you were stuck.... you were stuck, and a different differential wouldn't have been of much use either.

the ESP does the same as a LSD in that situation by applying that individual wheel's brake... Why would you use the emergency brake??? thats for cars that dont have ESP.. well and are rear wheel drive. Now disconnecting #11 will just worsen the effect! I think that your issue might have been more tread related or simply that there is a physical limit to our smarties in snow... that is unless you go with snow tracks!

I did pull #11 for the ride back home and it helped a bit. Still, it would be nice to have two wheels for traction versus one.

Yes, I would agree a mechanical limited slip dif would be a nice upgrade! I drive with the esp/abs off and when you trying to drift around a corner or cut a cookie the inside tire spins up and the car will kick the gearbox out of gear. It really sucks... Does anyone know how to disconnect that safety feature? Also if you wip the car around fast enough the car thinks itís been in an accident and will turn the engine off. Does anyone know how to turn that feature off as well? Nothing like trying to have fun when the car kicks itís self out of gear and turns its self off! Lol And no I donít have the wrong car, just trying to tune this one to me needs just like any other vehicle. 🤠

What in the world are you doing that kicks the car out of gear and shuts the engine off? I've literally jumped my smart with actual airtime and I regularly offroad mine without any of those problems.
