IIRC, Daman's weigh right at 26 lbs. Girodisc is like 3 lbs less. I've run many different rotors with different weights - and (honestly) I can't tell the difference. Even my data doesn't show any appreciable improvement. If a driver can differentiate a 3lb difference when driving a 3400 lb car, that's world class sensory perception IMO.

Also, all rotors get spider cracks. Maybe the scope of cracking was misread. Lots of people do it. For example, these rotors are just broken in and have a ton of life, despite what appears to be cracks.

I agree- I vote for Deman for the price and support. I dumped my Giro Discs- too many issues with them even though they eventually made good. I lost confidence , track time and costs due to bad machining - sold them new in box for a loss. My confidence is with Deman's product.
