i was wondering if i would need new axles with these suspension mods
-aluminum driveshaft
-driveshaft safety loop
-70/30 and 50/50
-rear upper/lower control arms
-torque box reinforcements
-drag launch springs or 4cyl in front
-drag radials

if i do need new axles, i will buy the 31 spline axles but does that mean i have to buy a new differential because im goin from 28 to 31??
i will be taking my car to the track this summer and my car is an automatic

What do you have for power or plans for future power?

As of right now no you do not. If you plan big power gains later on you will need to consider it at that time.

If your not planing on add a bottle , heads or cam swap you'll be fine

I still say no because your not really going to be much over stock power. With the mods you have and plan for power wise.

You are no where close to needing the stock axles replaced.
