1LE rear questions

[T-Type]

I'm new here and I joined because I hope you guys can help me out. I actually have a Pontiac G8 GXP but for repair reasons I am swapping in a 1LE rear out of a 2013 Camaro SS. I have a couple questions on the 1LE suspension. First, the one I got did not come with calipers. Looking around I see there are two options. There are black calipers that sell for around $240.00 each. The other option are red calipers that sell for around $1000.00 each.
What's the difference between the two? Other than the color they seem identical. Most importantly, can I just use the black ones?



What is the fluid GM recommends for the differential. It's completely stock as far as I know and I want to change the fluid.


Is there a torque spec for the differential cover?



Thanks in advance for your help.

Both Calipers are identical other than color: SS are black; SS(1LE) are red

Differential: I’ve always used RedLine

To change the fluid you just need a 3/8 wrench.
2 little nuts on the drivers side by axle and just under it.

Make sure to check on fluids.

It should include LSA-limited slip additive. If not just add a bottle or is it 1/2 bottle?
I believe the differential holds 1 bottle

I can't believe the price difference between the two for just the color. That's just crazy. Thanks for the info, I'll be getting the black ones.
