First, let me explain what a differential does and then I’ll explain the Limited Slip Differential (LSD) because I believe it us important to understand that first in order to truly understand the benefits of the LSDs.
A differential allows the left and right wheels on an axle to rotate at different speeds, which is essential when turning. Without a differential, tires would scrub, bind, and wear excessively in corners.
The downside of a standard open differential is that it sends power to the wheels with the least traction. If one wheel slips, such as in inclement weather and especially on hard launches, most of the engine’s torque is wasted.
A LSD will restrict how much faster one wheel can spin relative to the other. When slip is detected, it biases torque to the wheel with more traction, instead of letting all power escape through the slipping wheel.
Most people only do the rears on the SHO because they’ll get nice hard launches. You’ll feel it. It is AWD. The tires stick. This car already sticks pretty goods, and accelerates hard, and you’ll feel it even more with the LSDs.
The reason I decided to buy the front as well is because it will reduce torque steer and inside-wheel spin during hard acceleration as well as keep the car pulling forward instead of washing out.
There are other benefits too that you’re not necessarily chasing if you’re main purpose is straight line racing, but you’ll gain more grip when accelerating out of turns and more stability when doing some spirited driving. It will also improve traction in inclement weather. This includes ice as long as at least one wheel is still touching the pavement.
I know that is a lot. Feel free to ask if you need some more clarity.
