I agree. That was the one regret I had with this purchase. I purchased it from an online vendor, and I specifically asked if it was hubcentric and I was assured it was before placing the order. However, that was obviously misinformation that I later discovered after verifying it directly with forgestar. Unfortunately, after I tried to fight it and cancel my order, I was denied because it was already 4 weeks into my order. That was a rookie error on my part for waiting too long to verify it myself with the company directly.
But, I have used hubcentric rings before with aftermarket wheels on my previous car for over 95k miles, and I had no issues with them whatsoever. So I just came to accept these because I love the look with regard to style, paint quality, weight (21.4 lbs), and concavity for stock width (8.5) that are rotary forged.
I'm not sure if you're aware, but there are hubcentric 19s available from other manufacturers like VMR and FAST wheels, and are all relatively lightweight. For forged, obviously, they're custom forged so they're going to match the hub bore.
