I have a 01 Trans am WS6.. basically bone stock! and im lookn at getting a Moser M9 complete rear end setup in the next few months, just wondering what gearing is more preferred on a M6 F body.. i do alot of highway cruising.. and im kinda liking my 28-29 mpg with it but that 6th gear at 55 is kinda bogy..

What rpm are your running in 6th with those gears?

Also will i need my speedo recalculated?

I'm looking to take it to the track maybe once if not twice a year..
