I've had 3 different final drive setups in my car. 2 rules that I follow are:
1 Only let a qualified shop do the install, it's not for the beginner mechanic don't skimp on this or you will have a noisy or short lived diff.
2 Use a quality fluid in your diff.
The only 2 shops I trust to setup my diff are Spencer Fabrication in NH and Weir performance in CA I have had flawless work done from both companies. Both offer the same parts and options. DO THE UPGRADES IF YOU DRIVE HARD!!!!!


A 4:56 ratio would be the way to go with a manual daily driver
