I agree, the 9 inch would be way overkill. Personally, the best way for u to switch gears is to buy the whole carrier....of the ratio u like best, with the posi already installed. Then u can put it in urself and save the installation costs.

I do not theink the 600 will be overkill....but maybe more then u need. I think the 600 will be a good choice for you...gives u room to grom in the future.

With the gears u will feel the difference. Ur next best bet would be exhaust and/or a shift kit if u do not have one already.
