Upgrading rear shocks from 5100's to 5160's?

I've been wondering, would there be any advantage to changing out my rear shocks from 5100's to 5160's? The 5100's have been great, but I was curious if I'd notice any advantage or difference really with the 5160's having the remote reservoir, besides looks obviously.
I have 5100's up front, but I'm not currently looking into upgrading them to the 6112's.
Would it be worth the time and money to change the rears?

Thanks.

 

I m considering 6112s up front and 5160s rear as well...interesred in input from the hive too.

 

I went from the 5160s in my TRD Baja setup that blew out at 25k miles with 5100 shocks in the rear.

They ride almost exactly the same on road. Only major difference is that the 5100s get a little jumpy after a half mile going quick on a rough road where the resi shocks would stay planted. I rarely do this in the Northeast so I went with non resi shocks. But if your blasting across the desert, its probably worth it.

 

Thanks for the input. I won't be blasting the desert but Michigan roads are just as bad...

 

I have both,I would not bother until your 5100's are in need of replacement.
