Brass caliper bushings

[nsogiba]

During a routine pad swap and brake bleed last night I noticed that there seemed to be a small but noticeable amount of movement between the fixed caliper bracket and the caliper itself at each wheel when a significant amount of pressure was applied to the brake. I am assuming the rubber caliper bushings have worn out after 81K miles and a half dozen HPDE weekends.

I see FCP offers a rear kit for the E92 M3 - anyone know if this is an OEM BMW part or aftermarket? I have a store credit with them so I'd like to buy there if possible.

Also, this seems to be the same kit - any reason to pay double elsewhere? I have a charge pipe from X-PH on my X5 and the quality was decent.

Using the FCP part or X-PH? How's the fitment?

didn't really use my OEM calipers longs before i went to a Alcon BBK, but it's something i would do 100% if i was on oem brakes.

Sweet! I have the rears on the way from FCP and fronts coming from Bimmerworld. Excited to throw them in before my HPDE in a few weeks at PittRace.

I have been using the bimmerworld ones for some time now they’re all the same. Haven’t had any issues with mine but I do check them after every oil change interval and just make sure they’re greased up. Make sure you use slide pin lube.

FCP recommended a copper one but I see Permatex now makes a CERAMIC EXTREME slide pin lube (read in Hulk Hogan voice). Wonder what that's all about. ....

I keep debating going brass...not sure I am good enough with HPDE to reap the benefits.

That is what I use to lube my slide pins. After a track day when I'm swapping back to street pads, I notice there isn't a lot, if any, grease left on the pins. The small remains of grease that is left toward the back, hex side isn't as slick either. Not sure it's a really a problem and everything seems to work fine, but it's just an observation.
