AE86 LSDs

Well the catch under acceleration offcourse is that in case of heavy cornering you may not be having any wheelspin, but all the power still goes mostly to only one wheel that then brakes grip if you push the accelerator even more.

With LSD power is divided between the wheel with the least grip (but still having grip) AND the wheel that has the most grip making it possible to use more power and accelerate faster without spinning the inner wheel.

So the maximum power you can put down on the road is much higher with an LSD then without because you can put much more power on the road with the wheel with the most grip before traction is lost by overpowering.

This effect works even better with torston diffs, while a clutch diff will attempt to put equal power to both wheels, potentionally loosing power to the wheel with the least grip slipping, a torston diff will put more power to the wheel with the most grip. But for the same reason a torston diff is harder to drift, its harder to brake traction and once traction is broken suddenly the torque converter has no torque left to convert and you immediately loose all power to the wheels, it's like putting the car in neutral in the middle of a drift (all in my lamemans terms offcourse, but this is how my simpleton brain interprets what I've read about them).

What I do not know any theory about is what good locking the wheels does during deceleration. Obviously there is an advantage because people put down faster lap times when they have a 2 way diff. But I dont understand what it is because with deacceleration locking the diff would only result in more difficult cornering because the rear wheels wanne go straight ahead. It cant be more braking power, your brakes should take care of that, unless maybe braking on engine power has something to do with it......
