If anyone is curious, the J30 axles have been installed along with the 300zx N/A diff. I have pics, but they are not on my website yet.
It is awesome. It drives much better than before, feels more solid. Wet weather take offs from the stop light are much easier now as well.
The 300zx diff does weigh more than the open diff that was on the car. My sore arms can vouch for that. It feels good though.
I guess either suspension or exhaust is next.
Too bad 99% of the exhausts for the s14 look rice. I dont want a car whose *** looks like it just got out of prison.
