I want to run my 7.5" rear for as long as I can... What is the fastest anyone of you have run yours? ET's and MPH's? And what combos are you running... N/A, Supercharger, Turbocharger, Nitrous, Manual transmission, Automatic Transmission, transmission brake, foot brake... HP and Torque numbers... Pro-touring or Drag... Daily driver, or trailer queen? Also, do you think rear gear ratio would have any affect on how durable the rear is, since it enables the rear to take advantage of a higher torque range of the engine? And what is the weakest link of the 7.5", what is the first to go out and what would be a good way to fix/prevent it for a while?
