If you are going to have n engine put in with high H.P., say over 400 H.P. then i would suggest LSD. I went with a 525 H.P. motor and we decided the posi LSD was the way to go. My backdraft car is still being built but I have found the cars i have driven with LSD are more controllable when putting down alot of power to the ground. JMO
