C5 Differential upgrade
I'm looking to replace my stock diff (3.42 gears) with a newer (maybe upgrade at the same time) my 99 (92K miles) unit. Any recommendations: DTE, or Transzilla, Etc? I have brought a low miles Z06 tranny which it will go with it and I plan on road racing (not drag racing). Will a Stage 2 DTE be enough of a upgrade?

Talk to CJ at RPM Transmissions. They built my diff this past April:
This is what it looked like when I delivered it on a Thursday morning:

Oh yes, sell that Z06 trans. Its 1st and 2nd gear are inferior to the standard MN6 trans for road racing.

The Quaife differential is a very good item.
RPM installed one in my diff.
