I love the HRE and Champion wheels and I would by FAR pick them over any wheel from ADV. But the problem is that they lack concavity. The OP said he is looking for a Concave wheel and unfortunately the HRE and Champion wheels pictured pretty much lack concavity altogether.

I agree, but something else to consider.
Smaller may be lighter, but sometimes it can be a wash when you add in the tires. Ultralight 19s weigh more than ultralight 18s, but when you add the tires, the weights are pretty similar. Biggest advantage are the tire options for the 18s.

I do have one thing to add about disadvantage of 19: Assuming overall tire+rim diameter is the same for both 19 and 18, 19 has thinner tire and that means less compliance, and harsher ride.

Increase rear tire width and keeping front width the same DECREASES oversteer. Similarly interesting

Wow this is an excellent point that I haven't thought of. Is that for sure regarding total weight being the same (you've checked the math?)? I will quote this from now on.

235/40R18 26 lbs
295/35R18 32 lbs
18x8.5 is 15.3 lbs
18x12 is 19.3 lbs
Total weight = 185 lbs
Same combo, in 19s
235/35R19 24 lbs
295/30R19 31 lbs
19x8.5 17.5 lbs front
19x12 20.1 lbs rear
Total weight = 185.2 lbs
Looks like a wash - although this is only one example...and as you know, tire weights vary tremendously. Biggest difference that I found were the number of choices in 18s versus 19s. When you start picking wider tires in 18s, the numbers will fluctuate again.

DPE, D2 Forged, Iforged, COR, and Rennen all have great concave offerings. We have had great success with Rennen wheels and the concavity with the "extreme concave" line is incredible. Check out this BMW F10 build we did with Rennen R7Mesh extreme concave wheels:

They have and still choose not to let them on here. Trust I've already been down this road. We have been carrying this brand since Day 1.
This is still my favorite wheel from them.
