Sometime this week I will be receiving a new eaton posi differential and new stock gears 3.42. Since the new gears will be stock, does the computer need any new settings?

 

No.

 

cool, thank you

 

why are you going with new 3:42's?? did u break ur orignals? I highly reccomend you installing 4:10's with an M6, if your going to be installing gears anyways. i daily drive my car and they dont bother me at all. 4:10s should have come stock from the factory on a M6. Seriously look into 4:10s

 

Well for a couple of reasons:

About 6 mons ago I had put synthetic fluid in the differential and now its whining like a newborn baby lol.

I'm moving to Baton Rouge, Louisiana from San Jose, California and will be driving the Z. Also I would like to get good gas mileage (of course I'm gonna get a tune-up) on my 2200 mile trip. Then later I will be getting rid of the car because the car is not balance enough for me..too much body-roll, can never get the suspension right, too damn heavy. I'm debating if I should go ahead and buy a swaybar kit and a subframe connector on a 112K body/chassis.

So eventually I will sell the car and upgrade to the Z06 which is my dream car.

 

My Hotchkis sway bars made a big improvement with body roll, for what it's worth.
