I don't see why this is still being discussed. These new SC series monobloc wheels by HRE look amazing.
My 19" P40s have consistently impressed me over the last 4 years with their durability. (The stock forged 19s 220ms have impressed me as well) These wheels are just structurally so solid. I've hit nasty, nasty pot holes, expansion joints, dips, ridges and in some cases I was just waiting to feel the flat or bent rim, but it never came.
I can't say enough about my experience owning and truly putting my HRE Wheels to the test.
Maybe it's time to trade in my first gen P40...P43SC or P44SC for me
