Saw another accident right out front of a tow truck drivers shop, (Pure Grunt Performance, V8 guys). Whoever it was on the motorbike did not come off to well. It involved 3 cars and a motorbike. Apparently it always happens on that road.
Bryanlee38, there is 3 basic types of diff's. One is called a open diff, that drives the car forward with one whell, usually the easiest one to move. If turning left (correct me if I am wrong here Paul) it drives the car forward with the outside wheel. A locked diff, also illegal, drives the car forward with both wheels all the time. It makes your car a horrible pig to drive but makes sure 2 wheels always spin in a burnout. When turning a corner, the inside one skips as it is trying to cover the same amount of ground as the outside one which we all know is impossible, thus making the whole car vibrate and jump horribly. A LSD is the best of all 3 and has been explained to you by Paul. This guys car is open, but when open diffs are worn out, they become LSD soughta, very unpredictable what wheels will drive when and make the car dangerous if driven in a already dangerous manner.
Sorry for babbling up half the page but hope that helped a little more.
