Thank you very much for your write up. It's funny that you mention forged wheels bending and cast wheels cracking. My friend bought a set of BBS CH wheels years ago, and one of them cracked. He is planning on JB Welding the wheels back together. I told him that he is insane to do that and then put them on his e39 M5.
On a side note: Where I live the roads are terrible at best in the winter time. I had OZ low pressure cast wheels on my S8 for the winter. I bent 3 of them last winter, so I bought Volk forged wheels for this winter. So far so good. I truly believe they are a stronger wheel. I don't know what the weight load capacity is on either wheel, but I guess this means the Volk wheels have a higher capacity. How do I find out what the capacity is? I never see this number advertised.
