Rear brake drum help

Good morning everyone I'm new to this forum, I have a 2006 tundra double cab SR5 and I was deciding to do my rear brakes but when I took off the tire this is what I found. I have never seen a drum like this can somebody tell me what those extra bolts/nuts are for?

 

That’s a wheel spacer.

 

My advice is to get rid of it

Especially if you don't own a torque wrench, or you ever have tire shops manage removal/install of your wheels. Because over-torquing the lugs or the spacer bolts will result in cracking the spacer, which can lead to nasty stuff.

 

It's a spacer. At least it looks like it's the correct hub centric. I agree with @shifty` about getting rid of it. The only problem is you might get into a tire rub situation because someone used them to correct for the wrong offset on the wheels. Are they on the front as well?

 

Only reason I didn't mention that is because it's on the rear, which naturally sits about 1" closer to the flare, and has more leniency on backspacing.
