Correct!!!

If you are leaving 2 black marks or both tires are spinning simultaneously with TCS off then the car has an LSD. When you get sideways then the vehicle compensates, that is the yaw controller.

If our cars had an open differential you would NEVER leave 2 black marks and both tires would never spin at the same time. Period!!!!!

I have been racing for 22 years. I have built 3 vehicles form the frame up. I have rebuilt, swapped out, modified enough rear ends in addition to the 3 cars I have built to know what the Hell I am talking about.

Did you know you can convert a LSD to a locked rear end without buying a single part?


Probably not!!!

If the vehicle had an open diff with TCS one wheel would spin and the TCS would apply the brake to that 1 wheel. It would never switch to the other wheel!!!

In addition the TCS only applies the brake when the rotational speed of one wheel exceeds a preset % relevant to the other wheels. This preset is adjusted only by rewriting the code or selecting the "W" on the console. Switching to the winter mode. Read your owner's manual.


Please check out the link it describes all the different types of differentials. Obviously if we had an open 1 wheel would spin free. Hence If you sit there and bake the tire with one wheel spinning you would not move forward. With LSD you would move forward, and with locked both rear wheels would spin at the same rpm regardless if 1 tire is on ice and attempting to spin.
