1. Not warming up was part of the issue, not cooling down was the other.
2. It's almost like you have selective tunnel vision trying to find ways to justify your claims. You literally zoned in one one part of 034's response and zoned out every other part.
3. It's also funny how you're able to make such claims and have never seen the car in real life, and we're not there to inspect it. But then again most of your claims you've made have been off. You've claimed the f80 rotors are much improved over the e90 m3 brake rotors in terms of design and yet the design is nearly identical the f80 is just larger in diameter. This is kind of shocking that you'd claim this with zero backing as to why it's better, and you supposedly own both an f80 and e90 and have worked on both braking systems. So if you're unable to identify and observe the similarities in real life, then imaging your observational skills over the Internet looking at photos.... And that's being exposed when you blamed the mounting points being semi-circles and differently spaced.
4. You claim you see no abrasive or ablative braking, you do realize metallic race pads are only abrasive when cold right? Upon hard braking the brake pad reaches operating temps in seconds and now can be even more rotor friendly than semi metallic or organic pads. The abrasiveness would only be in at for a few seconds at most and there is a huge chance it won't leave deep lasting impressions into the rotor. It's going to add unneeded stress but it may not show, especially if it's wearing evenly across the face of the rotor. Even despite this you can see uneven wear on the Audi owners rotor right in the middle but you seem not to care nor notice. There's a reason why people running race pads don't have weird wear patterns on their rotors, beecause albeit they're abrasive it's not going to etch/wear multiple mm into the rotor.
5. You claim to be an aerospace structural engineer with 40 years of experience, yet without actual scientific evidence, statistical evidence of multiple repeated failures, or even seeing the faield item in real life you're able to claim a critical design issue. Yeah that's pretty impressive....
All of this combined with how you were incorrectly jumping all over the place blaming rotor mounting points spacing, hat design and gaps between the rotor, different metallurgical composition of the rotor, poor engineering practices, only looking at one part of 034's response and some how from 2 photos being able to deduce more information that the team that has access to the car and the owners testimony just trying to justify your reasoning that these rotors are defective based on 1 single use case just proves you have no idea what you're talking about. You're not interested in reality, you're viewing the information with confirmational bias to back your view point. This explains your post ton post appreciation ratio.

Yep, you’ve got me figured out. Your net worth in life is based on the reps you get on a forum. Sad. I have e92 M3s and a f82 M4. The f8x rotors are superior to the e9x rotors and if you don’t see the difference immediately then you shouldn’t be creating long posts discussing rotor design.
