Brembo on a budget! Let's make x5 great again :)

I'm going this route..just picked up some 6 pots off an M5. It won't be cheap but should be next level. Keep you all posted..

On another note need to solve for the rears..is a 2 pot off of an M3/M4 an option? Can I retain e-break?

The next step is to put back the original calipers, if things get better Ill rebuild the front MPBKs calipers.

You could go 50i in the rear. Much cheaper and closer in size. Several have gone that route with no issues.

Also quite sure it isn't motor mounts. You typically don't feel them at speed. Mostly at idle and unless they tore off it won't be violent by any means but more of a subtle vibration.

E brake has nothing to do with rear calipers/rotors as it's in the hub and without an adapter any other model rear calipers besides X5/6 Or M won't fit. You can run the M5/6 rear but again need an adapter with them as well.

Thanks for confirming..I've been perusing the M5/M6 forums and apparently it's an issue with upgrading their rears.

Ya their rear caliper seconds as the parking brake. It's got a separate motor attached to the back of the caliper that activates the piston.

Is it possible to put F85 size rotors on a F15 with 50i calipers? Would that look ridiculous?

No possible. You would need new calipers to fit the larger rotors.

Just got my M5 calipers delivered..these things are HUGE.

What am I missing other than brake pads of course - Looks like pins? Anything else?

Wow, so jelly.... You need adapters to mount them.

[fr_tz]

I plan on running 400m M5 rotors ...do I still need adaptors?

Panamera 4 pots for the rears

Damn! Those are bad boys! You'll need 1 sensor wire too (only need 1 per axle). And proper fluid of course to add.

It's so nice to see forum members actually taking it to another level.

P.S. I hope folks will chime in about adapters, as I lost my grip on this mod and I'm no longer knowledgeable. Things went far beyond my lowly 4 pot Brembo calipers lol.

Ive always wanted a 6/4pot combo for mine! what rotor are you planning on running for the rear Panamera calipers? also will they fit without a bracket?

As I understand it you don't need adapters if you run M5 rotors. Easy way to find out to be 100% is to pop a wheel off and detach the caliper and test fit with oe bolts.

Yes you need adapters and I'm pretty sure the calipers need trimming to fit properly. At least that's what the Russian company told me they had to do as they don't just sell adapters for the panamera calipers but as a full kit. But they do sell just the adapters for the larger calipers.

I just have F/R calipers right now but the rear 4 pots will work with F85 rotors. Please note the Panamera's calipers need modification in order to work. This is troniks kit option #3.

Do I need new brake lines and sensors for the front and rear or am I able to repurpose the existing ones off my 19 X6?

You can tell just by looking at these calipers that they won't bolt on without adapters. Hard to explain but the bolts on these go straight in to the caliper rather than horizontally across the caliper (perpendicular to the wheel hub).

I wanted to ask @tro-nik but he was banned apparently lol. Probably for advertising his adapters and various kits directly on forum threads rather than in vendors. He could have told us definitive answer. Sad, because in terms of brakes and different adaptations for x5 (and for other models) he was probably the most knowledgeable and he has adapter kits for almost everything lol. fr_tz - I'm afraid you need to contact him directly - he sells his stuff on ebay.

I know rules and such, but we are getting into supercar territory with 400mm+ rotors and 6 pot calipers lol, I wish tro-nik was here.

You are correct. He's actually missing the bracket entirely. Looks like they sent it without it. So yes he would need the oem adapter. But that oem M5 adapter should bolt up to the X15. Tronik sells one on eBay as well to connect to F15.

Now I'm really confused..my sets are missing a bracket plus I'll need an adapter or one or the other?

Can you show me what the caliper bracket you're referring too? I went on getbmwparts and their diagram only details a complete caliper without identifying the individual components. Looks like I'm missing some screws on the caliper itself. I do have the pins

Ya you'll have to get the bracket from eBay. The adapter is the bracket. By adapter simply saying the bracket may need to be special to fit the X5 vice an M5 which I don't think is needed

Thanks ..I'm going to see if my seller still has the original bracket. One good thing is that the fronts cleaned up quite nicely. Don't even need to powdercoat them. Practically perfect other than the fading M. I'm going to see if tronik can match them before sending out my rears.
