Hard to measure the impact of any single drivetrain mod. Most people add a bunch at a time or add them in different order and it skews the impressions.
I will say that I find replacement bushings and inserts for the transmission and differential to be very noticeable, eliminating all the movement of the shifter. I was unhappy with the amount of slop and lash it had stock, particularly when letting off the gas in lower gears and higher engine RPM.
I did most (if not all) drivetrain bushings (except engine mounts) and am very pleased with the result, but it wasn't until the last mod that it really made a big difference. It might be that the last one (the diff bushings) are the important ones, or that all the bushings/inserts are needed together.
I did Perrin rear bushing, Whiteline front insert, Torque Solutions front carrier bushings, Whiteline rear subframe inserts and Whiteline diff inserts.
