The rear of the car is looking shinny like the front is. The 4 link and Trac-bars are all polished stainless. 
 

The rear-end housing looks big compared to the rest of the other pieces. Lots of strength which is a good thing.
 

Now you can see the 4 link bars a little better. It's a shame they'll be covered by the body. 
 

Here we have the rear disc brake which is 12" in diameter. The front are one  inch smaller then the rear. Those calipers sure are shinny.
