So my rear diff is all apart. I have a newer trak loc, 8.8 rebuild kit and crush sleeve eliminator. I got rid of the 3.27s and picked up a used 3.55 gear set practically free. What I would like to know is if it would be smart to acquire some 3.73s and put them in while I still have it apart. Transmission is an M5R2 and I do not drive my car on the street, road course only. Gears 3-5 are most important to me to try to optimize. Engine is 306ci and I rev it to 6700RPM.
