Explicit resolution reports before identified causes, performed actions and suggestions. Within each level, matching component labels precede direct query mentions and inherited thread context; successful versus unsuccessful discussion counts, owner confirmations and independent discussion support determine order. This is not a probability of success.

TL;DR dealer replaced his covers after it started during a track session which caused a warning light (ditto at last Winton), he thinks they are under engineered.
Leading evidence: 'Replace covers' (no explicit attributable resolution; this is a reported action or suggestion). Across 1 matching discussions, The most frequently discussed action is 'Replace covers' (1 discussions). For that action, 0 discussions report a resolution and 0 report an unsuccessful attempt. No action has an explicit, attributable resolution report under the current rules. These are forum reports and suggestions, not a confirmed diagnosis.
Source reports, not a diagnosis or a success probability. Counts refer to discussions and can overlap.
These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

Has anyone experienced warping of the dust covers for their brake discs? I've had it twice now after attending Winton.
Are there some upgraded dust covers available on the market?
Thanks Pauly, did search rennlist but didn't find anything other than them talking about the handbrake covers.
It's part 3 in this diagram.
When the aluminium heats it ends up warping onto the edges of the disc which then starts with a subtle sound similar to the sound of a rock bouncing around inside the rim - as I previously spoke about on the SMT last time. Once it really heats up and then cools down it's constant direct contact producing a constant high pitch squeal. The fix is easy as it's just a matter of trying to bend it back with a few hard taps on each of the corners.
It's more annoying than really harmful, but I would prefer if it didn't happen. I guess I could possibly remove them, but I'm not sure what effects it would have.
you'll probably find them referred to as 'backing plates' or 'protective plates'

Thanks Russ.
Found a thread talking about them on Rennlist for 928's (
http://rennlist.com/forums/928-forum/632758-what-s-the-real-purpose-of-brake-dust-shields.html
) and what the purpose is but nothing about them on the 996.
General consensus is that they stop debris interfering with the pads which is what I thought. Other theories include stopping water splashing directly onto the rotor as well as stopping brake dust attaching itself to other parts of the car (which I don't completely believe)
Google at least yielded another guy with the same issue

Looks like I might just leave em on and bang them out for the meantime, but I'll have a chat to Michael from Autoart and find out if he's had anyone else with 996's which have had the issue and if he has the on his track going 996 GT3
they really just keep debris and stuff out of your brakes, I've had cars where I took them off as they were deformed an NLA and never had an issue (and that chuffing noise where they rub on the rotor always got on my nerves)
An AU falcon for example by design doesn't have backing plates and has no issues
