I just went with an rpm one. Im still on break in but Ill report as soon as I can romp on it and can report any true data. With rpm you get a little more bang for your buck but with dte you get a new case I think. I dont think a z rear will bolt up Im pretty sure its different.

Its not direct swap compatible as-is. The Z06 tranny and rear use a 30 spline output shaft and the C6 uses a 28 spline shaft.

You can have your tranny rebuilt and use the the 30 spline Z06 output shaft, or use a Z06 tranny and you would be good to go.

This is also assuming you have an 06 or later car. If your an 05 you would also need to change the trans tail housing to the 06 and later one.

I went with 3.42 because Im an auto and didnt want to get too crazy. A lot of guys with manuals depending on the application have great success with 3.90 and 4.10. I think 3.73 is the more mild application on m6 cars but it really depends on what you want to achieve.

I just wanted a faster car at the strip without going overboard.

I went with an RPM 3.73 STAGE II, very happy so far. I think it's all in where your located. I would try to deal with someone as local as possible, instead of going cross country.

"Cheap" was probably the wrong word used. We can build our differentials at a lower price because we do them in house, and have been doing so for years. We'll guarantee that you will not find a better differential at a better price, period. We stand behind our rebuilds with our 30 years of being in business.
