Depends on where you want to end up. If you want to be in the 10's, 9's and mostly a track car, then you may was well do it now. if you are just going to be a quick street car then the stockers will be fine as long as you stay with street tires and not going with street/drag tires. The stickier you get the harder it is on the axles.
as of right now im using nittos street tire. just mostly street racing, maybe track here and there not much. i just dont want to break an axle at the track my car is an 86 and its 20 years old but im going to weld my torque boxes for sure
if i get the axles i might as well get the posi unit too for the 31 spline axles. whats a good posi unit for the street and little track use thats not going to kill my pocket book
