Rear Diff.
 

what does locking the rear differential do? is it good for drifting, high speed, acceleration? does it make it handle different? please help.
btw, i know how, just want to know what it does to the handling and speed.
thanks

does anyone know?

It gives u positraction rear end. letting u spin both wheels at the same speed. Great for burn outs in real cars.

i did it and it seems like its able to do donuts better. btw, i have the s2 drag with stocks all around.
