55+ pounds seems a little excessive for 17" wheels- that's heavier than most 20" truck wheels! I was under the impression th weight was in the mid to high 20s per wheel.Originally posted by C280Sportster
The heavy AMG Monoblock kill some of the C43s quickness...if you lose the monoblocks (55+ pounds, ouch,) you might be able to drop 20 pounds a wheel... that's close to 80 pounds of (un-sprung, I believe) weight.
This is just a minor point, but I don't want owners freaking out about their wheel weight too much- but I do agree lighter wheels will definitely help!
