Default Update on my diff decision

I had another thread going about which diff to buy for my 02 C5 6speed but it got closed since DTE, RPM, and ECS kinda got into it I guess. Anyway to make a long story short if any of you was wondering what i ended up doing, i ended up buying the Stage 3 from RPM transmissions w/ a 3.90 gear like you guys suggested.
The customer service was excellent at RPM right up until i drove 450+ miles to pick it up and swap it for mine but i got stood up twice that day but luckily i believe either it was Rodney &/or Todd showed up and i ended up getting it in the end and looks like a nice diff. i hope its as strong as it costs lol cuz damn I hated spending $2600 but i wanted RPM's reputation to build me a good diff so i'm gonna give it a whirl!
Plus i just bought the PFADT trans brace and motor mounts to compliment my existing DTE brace as well...... Lol anyway i hope this driveline is practially bullet proof now.
I was gonna call TJ and ask but i figured i get some thoughts on here first. What gear lube do i run with that rearend using the carbon clutches in it etc.????? And do i put the additive in it as before too?

Thanks!

After spending all that money and time, why would you not ask RPM directly? Who cares what the forum thinks, you have to follow the builders recommendations.............if you want a warranty.

I just purchased the C6 ZO6 Diff output shafts, spider gear for the short shaft, seals for my 02 Z from Gene Culley and Patrick. I going to purchase some other hardened stuff like the clutch pack springs and the spider gear cross shaft to help the rear survive. Ordered the 300m cross pin shaft and Heavy Duty Clutch pack springs from RPM.

Will be going thru it my self very soon. Will post some pictures.

FYI Update: RPM suggested Valvoline 75/90 synthetic w/ GM limited slip additive for the new diff.
