That, or you're really putting down a frick ton of HP, which most FWD's aren't.
A LSD will increase your understeer in most situations with a FWD. I'd prefer without unless it were a straight line race, or I was dealing with surfaces with extremely uneven grip. |
Others have already answered this but I think it bears mention that LSD refers to
limited slip differential, not zero slip differential. All differentials allow
differences, or differentials between the amount of torque and the turning speed of the 2 wheels on opposite ends of the axle. An open diff is basically a 100% slip differential, ie. It allows 100% slippage between the two wheels. One side gets 100% of the torque, the other side gets zero.
A stock Porsche 911 LSD used to be 40%, (if not mistaken), which offered no disadvantage in road driving under any condition, IMO. A 0% LSD diff would be a locked axle. The Evo I recently owned briefly had a Quaife LSD in the front axle that greatly reduced the *one wheel spinning* problem while exiting corners under power, particularly when the power was increased from stock.
An intelligent limiting diff in a FWD car would be one of the best improvements you could make, I would think.
