Pro comp series 51 vs 52

[BP 92]

I'm at a loss. Couldn't find an answer even using google.
What is the difference between Pro Comp Series 51 and 52?
Both seem to have same design, # of spokes, same material, same center hole diameter.

Anyone wanna inform me?

Also, wasn't sure where to post this question so if inbred to move it let me know.

Since 77 people have viewed your post with no response, I'm going to move this to the Wheels & Tires section for you.

For those interested.
A quick call to pro comp (shoulda done it first) revealed they are the same wheel
They are phasing out the 52 (manufactured in China) and replacing with the 51 ( manufactured in Chula Vista, CA).

Other than manufacturing location wheel is the same.

Or at least that's what I understood from the conversation.
