IDK, 270mm is what they run on 220 lb dirt bikes, and stop them well. Using them to stop a 2000 (guesstimate) lb car? If they work out, that's a great price for more stopping power, IMO.
My X3 is in the shop 3 hours away or I would measure. Anyone out there able to do this?
I will say that looking at the photos it seems like the relocating brackets for the calipers move them out an inch or so which would be 25mm....meaning stick is maybe closer to 240mm...10ish inches. While an inch in diameter may not seem like much it’s quite a bit more friction area in circumference as the rotor turns. The science is sound. Bigger rotor equals more stopping power via surface area and if I’m not mistaken the actual physics of having the pressure points further out in the rotating mass is more efficient too.
Like someone else said, I’m kinda willing to try anything at this point to improve the brakes....
From a brochure I found online for a 17 DS. Should be the same for all X3'S.

Front Dual 262 mm ventilated disc brakes with hydraulic twin-piston calipers
Rear Dual 248 mm ventilated disc brakes with hydraulic twin-piston calipers
I just pulled up the PDF specs for my XRS I had forgotten I had saved...same stock measurements mentioned above.
Regarding the lack of difference in the front/rear Streamline specs: I’m guessing the 270mm would fit the rear with the appropriate caliper placement....I mean there is definitely the same amount of space inside the wheel right? I would guess the difference in the front/rear kits is probably with the caliper brackets. At a minimum they sit in different locations on the respective knuckles....
For the rear going from 248mm to 270mm would be very effective and well worth the money.
For the ront, going from 262mm to 270, I'd pay 50 bucks, no more. The front should go to 285-290mm to have an balanced effect.
Going to 270mm front and rear would be dangerous.
The rears would lock up long before the fronts would effectivly slow down the car.
Stepping on the brakes in a turn and the rears locking up will give you a spinnout, and at the wrong time, a rollover.
Isnt ~80% of your stopping power in the front brakes? Hell I ripped the back brake off my dune quad years ago and havent missed it a bit. Front brakes are where its at especially in the sand
^^My thoughts exactly but if someone does try it you could always add a bias control. I would like to hear how just a front conversion works. I question if there is enough change in diameter on the fronts to tell a difference.
I got the galfer pads yesterday and the big brake kit for the front earlier in the week. I won't be able to put them on until next week so it could be a little bit before i can give a report...

I race a lot my xrc in rally races, ebc brakes pads are the best imo, the do not ruin your rotors like ceramic ones and last a lot, if you don't mind the squeaking noice every time you brake, they are really good, the original ones overheat too fast..
I missed the post title and first post because I was researching the streamline oversized rotors on Google and linked over to this post. I read back through the post backwards but I guess I didn't make it all the way to the top. I ordered front and rear rotor kit from streamline. After seeing your question and referencing the first post, I'll try the pads if I'm not satisfied with the rotors or after my pads wear out.
I just installed the Galfer pads all around and went with the Motul 660 fluid to see if I can get a little more braking. I will go with the Galfer rotors if this does not help.
How many miles do you have on them? Do you notice any more brake squeak with the EBC pads over stock? Thought I saw some other comments in this regard
