All I know is that the SH is a little heavier and comes with a spoiler (unless it was added on a base) and also comes with a lights on the doors, and most importantly the ATTS system (Active Torque Transfer System). It allows for better performance in curves...which is amazing!!! I love it...I know some people who dont and think its a waste of weight...oh well.

I have never heard of a SR-V before.
