im getting my limited slip rebuilt real soon but i dont know if i should just save up some more money and replace the differential and get 31 spline axles. are 28 splines capable of holding up to the mods in my sig + im doing h/c/i over the winter?

the 28 spline axles will hold up to a lot of beating9 prolly 350-400 hp but if you got the money for moshers hardened axles now would be the time to install them while the rear end is torn apart. i guess it all depends what your use of the car is, do you drag race it and burn out a lot or so you drive it on the street most of the time?

get the 31's its good insurance. ive seen 13 second cars break axles and ive seen mid 11 second cars run them over a year. i cut two low 1.5 60ft's then i decided to change mine. i drive my car over a hour each way to the track.
