Raybestos 7038R rotor heads up.

 The famous Disk o tech 11.75 rotor upgrade has a part not up to par. Sold as an exact copy of the factory part, it isn't. The 5 sets of extra ribbing on the inside of the hub has 4 pairs missing. On factory rotors there are 2 ribs between the 5 lug nuts. The 7038 only has one set.
 This ribbing was added to prevent hub/disk cracking.

This could use pics.


Who else still makes a good version of the rotor?

What I ordered: https://www.rockauto.com/en/moreinfo.php?pk=391220&cc=1092686&pt=1896&jsn=10549
See the ribs? 4 sets missing on new part.

It's possible that improvements in material over the year deem the extra ribs unnecessary

Yea that's the 43.00 each gamble I'm playing. (Never had any issue with Raybestos.)

It's possible, but I'm about as skeptical as I could get.  Modern Chinesium vs original Mopar metal.

I could have go with the 11.75" rotors upgrade (drilled and slotted) if I was found pin kind calipers brackets for the upgrade. I don't want to change to slide calipers. But wasn't posible on a decent price.

So I bought drilled and slotted 10.9" CENTRIC brand rotors and ceramic pads.

Yea had I known the pics were wrong even showing "made in Canada" cast into the rotor. The box was fairly hammered also.

Where did the current producer get the idea that it was safe to skip some of the ribs?  Was an earlier OEM version of the rotor done that way?
