do you run anti-rattle clips on track

[kolosy]

my bbk came with anti-rattle clips which i installed, but they recommend not using them on track:

Some of our customers have been running the anti-rattle clips on track and so far we haven't come across any issues. However, we would recommend using the pad retainer tube for track to ensure the pads move freely under extreme track conditions.

what do people do? these appear to be the same design as the ap racing ones... https://paragonbrakes.com/anti-rattl...9661-calipers/

They just put down pressure on the pads so they're not... rattling around in there. This could cause a minor amount of dragging so they don't recommend it on track so you're not lightly dragging your track pads on the rotors at high speed.

Will it matter either way? Probably not.

my Bimmerworld Alcon kit came with them pre-installed

doesn't make any sense... the clips don't restrict movement in a negative way.
you'll be fine either way regardless. just know they'll clack on occasion and thats normal.

I remember the first time I ran track pads on the OE brakes with no clips. Clack - clack - clack...WTF is that?

Same here, thought something had come loose in the rear suspension.
Went underneath to check, couldn’t find anything obvious.
Sat in the garage and cried to myself “All I did was change brake pads…WTF?’”

"oh, that sound. those are my racing brakes bro. i need racing brakes because i track my racecar."

🤣🤣🤣

OE brakes and no clips? Thought the clips are literally integral to how they work.
There is play in the slider mechanism for any sliding caliper. I'd expect unequal contact on the disc face and wouldn't be surprised if inner rings formed.

On monoblocs, do away with them.

Bimmerworld recommends not running the clips when using brass bushings in the the OEM calipers. I've been running without for years with no issues.

Brass slider makes sense as that takes out considerable flex in the system off the brakes. I might consider that then actually.

I run the anti-rattle clips on my AP9660 calipers up front without any noticeable issue.

It's probably not nearly as much flex as you'd think. The slide pins have very little load on them. I did them almost purely for reliability as I was worried about melting the rubber.

wait, aren't the slide pins what secure the caliper to the wheel hub? do you mean very little longitudinal load?

Common misconception I think. The slide pins only job is to keep the caliper located on the pads and let it "float" side-to-side. The caliper's only job is to squeeze the pads, that's it, the radial force the rotor puts on the pads is transferred from the pads to the caliper bracket (not the caliper) and into the hub.

Think about how small those pins are and how much force the rotor imparts on the pads. If 1/1000th of that load went into the pins they would immediately sheer off.

yeah, it makes sense, i just can't think of where the contact point is between the caliper and the bracket..

EDIT: Just realized you said bracket to caliper. There isn't really a contact point between those two. The load goes directly from the pads to the bracket. The caliper is not involved in it at all other than squeezing the pads.
