Big brake swap issue.

Doing a big brake swap(231mm S13WL) on my Or Tacoma Double Cab prerunner along with Bilstein 5100's and OME 2881 coils and SPC UCA's.

I just realized that I ordered the rotors for S13WE calipers. It seems to be fine so far. The problem I'm having is wheel stud length. I have stock Steelies with a 1/4" wheel spacer. I had the same rims and spacer on before though and it was fine.

Now I'm really confused, just measure the thickness of the new rotors vs. Old. New rotor 6.22 mm thick where it mounts to hub. Old rotor 6.85.
I know it's not much, but.the total opposite of what I expected to see

 

Get the correct rotors.

 

I just looked up the specs, it's the exact same rotor.

 

The stud length should be the same regardless since they are both for Toyota hubs.. something is not fitting correctly.

 

I figured it out. The opening on the new rotors matched but the bevel was different. I just hid to clearance the chambered edge out a bit.
