My argument.... is that in a year or so, numerous aftermarket companies will offer a drilled/slotted rotor for half the price of what BMW does.... and in many cases, even higher quality. Spending big $$$ on BMW branded rotors seems silly, when pad upgrades will provide far better braking anyway.

Looks are important too, of course.... but I'll just wait for stoptech or somebody to make a rotor upgrade of that's the case.

X5M uses different brakes(6 pot). However X3M uses the same calipers, so their rotors should fit on our vehicles.

Interesting.... I didn't know that. I may look into that once parts become available. That would be a nice upgrade. I exchanged multiple conversations with the Tronik folks in Russia, and to date, "upgrades" to the M50i just aren't worth it. That may change once a few X5Ms have been crashed, and parts become available.

Rear brakes need an upgrade FAR sooner though. I can't believe BMW is still installing those same single piston cast calipers on the rear.... PARTICULARLY on the X5M..... that's just embarrassing and shameful.

Interesting. Do we have any way to confirm it is the same? I would love to add them to my truck.

Here are the part numbers for the front and left.

X3M Front Left: Disc Brake Rotor - BMW (34-11-8-054-825)

X3M Front Left: Disc Brake Rotor - BMW (34-11-8-054-826)
https://www.getbmwparts.com/oem-part...MtMGwtbDYtZ2Fz

They are $350 each which isn't awful. The problem is the rear caliper is definitely not the exact same part number as the G05, so we would have no way to know if that fits without test fitting it.

The rear rotors on both is 370×24, so there shouldn't be a problem.

Maybe... I've watched videos of rear brake pad installations on both the X3 and X5, and the EPB is present in both, but clearly a different unit.

While the diameter and width of the rotors are the same... that doesn't necessarily mean that the....... "offset"??? Is the same. Not sure what term is used to describe the offset or "ET" of a rotor is.... but similar to a wheel, it matters.

Then.... there is the hub diameter to consider as well. Not sure if they are the same. That would also cause non-interchangeability. It is perfectly feasible to consider that the much heavier X5 has a larger hub, larger bearings, etc than the X3 does.

Maybe not.... maybe they fit perfectly.... but there is more to consider than just diameter and thickness of the rotor

Good info, there's so little options for G05 right now it's annoying.

Agreed. There's a few MPerformance parts, a few odds and ends..... but if you want something that is actually going to make an "impact", you have to start with the tuning, wheels, tires, suspension, etc.

It's understandable though. A typical BMW driver can't and won't turn a wrench to save their lives, unless they are an enthusiast, which is generally reserved for full-M cars. Plus, the non-M G05 isn't exactly an "enthusiast" car, so aftermarket companies aren't as willing to invest in R&D.

However... the X5M came out much later, and relatively recently, and I foresee a LOT of interchangeability between aftermarket parts..... which is a good thing. X5M production numbers are low, so it may take a while..... but I believe we'll start to see much more aftermarket support for our cars within the next year.

I suppose you can always cover the car in adhesive-backed fake carbon fiber stick-on parts??? LOL Ebay is full of them

[Ninefourteener]

Sooooo...... wheels should be arriving any day now, and I had a day off, so I figured why not go ahead and install my BBM lowering links. I figured I'd start with a moderate drop, because it's much easier to adjust them to the new wheels, than it is to do a full installation AND adjust them.

Dropped the front 1/2 inch
Dropped the rear 1 inch.

First picture - OEM SPORT MODE
Second picture - BBM SPORT MODE
Third picture - BBM LOADING MODE

I'm doing a full write up, installation instructions, and specific measurements calculation in the suspension forum. Easiest suspension job I've ever done in over 25 years. Less than 2 hours,.and that was including taking pictures, documenting lengths and ride heights, and adjusting...... for about 100 bucks? Lol

When I know that a traditional suspension takes 8-12 hours (I know, I've done at least 15 full suspension jobs)... and leaves your back sore, knuckles bloody, and costs thousands of dollars worth of parts???

Shiiiiiiiittttt....... I'l probably never buy a car without air suspension again. Way too easy. Lol

[bforbrian]

A write up with instructions would be so amazing to have! I intended on having links installed at a shop but if it's easy enough (which you say it is) I may just do it myself. Let us know if there are any particular tools that most people do not have in their garage...

Thanks Auricom.

Here's the most important picture of all the ones I took today.... and I have no idea why it's sideways.... lol:

[TomCat6065]

Looks great...nice to do your own work!

[Ninefourteener]

Shit's fixxin' to get real just arrived 10 minutes ago.

I had to at least take a peek at one of them.

[TomCat6065]

Very nice! Can't wait to see them mounted.

[Ninefourteener]

So..... the place I bought my tires (and installation) is closed until Sept 1st. Apparently they go on holiday for the entire month of August every year. Because..... Europe. Uggghhhh.

So.... I've got a 10-day wait before I can get them installed.

I'm actually going to post up an entirely different thread, because I am SO impressed with Vossen as a company. They went WAY above and beyond to get these to me.

In the meantime.... I had to open and check for damage. Just to be safe. They are absolutely GORGEOUS. ABSOLUTELY FLAWLESS. I couldn't be more impressed.

And..... the wait is over, and it's no longer a surprise as to what the ET/offset is. I intentionally didn't specify what I wanted, because there's no information out there on the correct fitment on a set of wheels this wide. So.... I left it to the experts at Vossen to make that determination.

These MFers are going to look like BEASTS. This is a SUPER aggressive fitment, and will likely require a bit more tweaking of my droplinks to set the ride height perfectly. I'm looking forward to it.

22x10.5 front, ET 19
22x12 great, ET 20.

That means, they'll poke out about 15 and 20mm more than my current setup.... or 30mm and 40mm more than stock fitment.

B E E F Y.

More to follow in 10-ish days.

[GOLFFRR]

looking forward to seeing the new wheels mounted

Most aggressive offsets I've seen so far!
Keep the pics coming.

My wife and I brought our Harleys with us to Europe...lots of great riding.

So.... it's been rainy, cold, and haven't had the opportunity to do the full brake caliper re-coloring, re-adjusting of droplinks, etc.

No change today in the grey weather..... but I couldn't stand just staring at them in the garage. They had to go on.

Car is filthy, tires still have Install goop, cloudy grey day, and I'm a shitty photographer anyway.

Wish I could show the "pop" of the color..... it's impressive. Not on a dark, cold, rainy day though. Can't wait to get some "sunlight" pics.

But..... I'm incredibly pleased with these.

Front:
Vossen HF-2 "deep", Satin Bronze

Looks great in bronze. Good decision.

I found a last thing you can still change. Why didn't you already? You have done so many things. That would have been one of the first for me.
