Whatever ratio you decide on I'd stick with FRPP gears. Have heard of others being noisy and whining even with good, knowledgable installers. Still loving my 4:10's but have heard from some that they are too much in a supercharged car for a daily driver and then again other have kept them even after supercharging. I'm used to mine and love stomping on them when I get a chance. Combined with Bama tunes they make a good combo for me! And have Rick do the install!
