In a FD built up making 450whp roughly.. what needs to be done to the rear end to make sure you dont shell it driving it around town and hopping on it from a stop light? ya know basically I dont wanna blow my rear cuz i over looked it!

 

hmm will a kaaz locker do it? or do i need it with the 300m axles also?

if it helps i plan on running around town with drag radials in the back all the time..
