9-inchers are overrated - literally. Back in the day, Mustang modders ripped out their "weakling" C4 trannies and 8-inch rears and put in the brute C6/9 inch combo.

Thereby adding more than 150 pounds to the car for no good purpose. Many *very* hot setups (9 second bracket) run well-built C4s and 8-inchers in pass after pass, getting more from the weight savings than from the additional strength of the bigger pieces.

Unless you're running over 600HP and plan to have your foot deep in the throttle a lot, a well-prepped 8.8 is all the rear end you need. And a helluva lot lighter than a 9-inch.
