hello. so as far as i know the rear diff in a N/A crossfire is just an open diff. so what i,m wanting to know is if there is a way to make it a limited slip diff. i don't want to weld my diff, if possible id like to know if there's anything that can be done to the inner workings of the diff to make it act like an LSD. or if there's an LSD on something else that can swap over with minimal modifications
