Today we’re cranking up the power on a X6M, and the gains are rather awesome.

The X6M in question originally came to us requesting some ideas about changing his brakes. Upon coming to the shop, a little bit of chatting about BMWs revealed his interest in a dyno tune. While we set the car up properly for its dyno runs, let’s take a look at the two things you’ll notice most about this specific X6M.

The most obvious change to this vehicle lies at all four corners. The OEM wheels were replaced with a set of Savini Forged SV-34s, the exact same wheel you may have seen on the GTHaus/Meisterschaft E92 M3 widebody, which has been shot numerous times by our good friend Jeremy Cliff. It’s been all over the internet as much as some memes have, so you’ve probably seen them even if you don’t recognize them. Behind those wheels lie Rotora’s Big Brake Kit for the X6M; however, these aren’t your dime-a-dozen standard material brake systems — this is Rotora’s carbon-ceramic offering. While they do tend to squeak a bit in normal driving, they’ll stop just about anything short of a freight train loaded with solid lead. And even then, they’ll probably put up a hell of a fight.

Aside from the definitely-not-stock-at-all wheel and brake setup on all four corners, the only other thing you’d notice most readily is the M-badging. While the dual exhaust outlets are a good sign that something isn’t quite right under the hood of this X6, the badging is what really lets people know that there’s some serious power waiting to be unleashed. Eventually, they’ll just paint a giant ///M on the side of the vehicle and be done with it. Hopefully that didn’t give them any ideas, but the badging looks nice when contrasted against the stark white exterior paint.

And now for the fun part of the post — the gains. Sadly we didn’t capture any video since *somebody* didn’t shut off the microphone last time they used the camera, killing the battery and leaving us without a replacement in its stead. However, the dyno graphs put the proof into the pudding, as we see low-end gains of 75 awhp and 85 awtq. At redline, there’s a gain of 25 awhp, but no matter where we are on the power curve, the owner will definitely be feeling some extra pushin’ behind the cushion. Will he be back for more? Time will tell!

We’ve got this short blog post today because we’re running out the door very soon to shoot the RS6 with local photog Matt Magnino. Expect some very sultry shots to hit the internet soon!
