Help with identifying rotors?

[stealthtt24]

So I got these 2 sets of rotors in a bunch of parts when I purchased a GVR4 and cant remember if they said they would work or not, anyone know?

the 2nd one looks too worn/thin...1st one might but you'd have the measure it

The sloted is just a upgraded stock size 4 bolt vr4 rotor . It has the "R" on it to indicate the right side, and the other 2 holes are for the abs bolts. The rusty rotor is your rear rotor.

So the only one worth anything is the front 2, thanks!

Bumping this cause I was going to use these rotors to save some cash. Saw some etching on the side and it says "BR 31218 MIN THK 22-4 MM 101700". Will they fit and I assume they are for the rears correct? Stock 4 lug going on stock size calipers. Also I'd like to get matching front ones, anyone know what would be the equivalent of these? Thanks!

Stock rotors are vented in front and non-vented rear. Looks like those are front rotors.

I matched them up to my old rusted front rotors and they look the same, other than the drilled, slotted, and no rust part. Thanks! Guess I gotta grab some rear ones now.
