School me on BMW/Porsche brake upgrade options.

Sorry, but in my opinion stock calipers are not "pretty damn good" I think they're absolutely junk. To be completely honest, something is terribly wrong with my current calipers, even after 2 rebuilds so I'm going to scrap them. For some reason the pads are sticking to the rotors even after releasing the brake pedal. Yes I've lubed and cleaned the guide pins, yes I rebuilt the calipers correctly, yes the master cylinder has been replaced, yes the servo works properly, and yes all brake lines have been checked for kinks.


This is causing the pads to CONSTANTLY drag the rotors causing a ton of heat, accelerated tread wear, pad deposits, and a shimmy that is driving me effing bonkers. I can turn the rotors and the issue is gone for about 2 weeks, then its back. I have no other ideas here regarding the fault besides the calipers themselves, so I'm chucking them.


I would rather spend 250$ on lightly used 4 pots than 400 on brand new e36 OEM M3 calipers.


That's actually interesting point, did you try to compare contact area size of OEM brake pad and pad from e38 caliper? 4 pistons are fine, but what else you'll gain?


I will no longer be dealing with a sliding caliper design.

Weird double posting like this, but you could get lightly used e36 calipers for cheaper still, and get better performance to boot.

What about those 4 pot porsche calipers on rally road?? I would go for those if I was in your position and wanted a brake upgrade...

[m3f_Mr ///M3_1448fff35e]

OK. To cut to the chase, I'm looking to upgrade my front brakes for less than $900. Obviously I'm after a multi-piston caliper and drilled and/or floating rotors.



I'm officially giving up on trying to source 840ci calipers for the 8 series 4 pot brake upgrade. NO ONE has them. Not even the re-builders. Trust me, regardless of what their website says online, they don't have them I've called them all.



I hear a lot about Porsche brakes working on our cars, and I've seen it done but I don't know enough details about what fits and what doesn't. We all know Porsche parts are more common than 8 series parts so I'm all ears.



What do you guys know?



Sorry for asking, but are you intending on racing your M3 ?

How many miles are on them?



Price?



:hmm:

They have 120k on them and I never had any problems with them either. just wanted to upgrade to big brakes for the track. They worked great when I pulled them off. They have Stainesss lines attached as well, but not sure the condition of the lines off the top of my head. IDK....if you want them shoot me an offer I am reasonable.
