Ive been wanting to go to a 3.55 or 3.23 posi. I have the stock 3.08 right now with 245/45/20's. If I change my tires to 255/35/20 that will get me pretty close to the 3.23's(i think). Does anyone have this size tires on their stock srt suspension? (i know it looks good on a lowered suspension) How does it look on stock suspension? And what would the exact ratio be compared to stock. I was just thinking of this because I need to buy new tires and I want a little more pep off the line like you get with lower gears. opinions please.

Effective gear ratio is about 3.24 with the shorter 20's wherever you get them from.
