2016 28I MSport Finally Arrived...already thinking about mods
So after waiting for 5 months almost to the day that I ordered it, my long awaited first ever BMW arrived a few days ago. I posted pics on the "official" photo posting section of the forum (http://x3.xbimmers.com/forums/showth...=456656&page=3) I'm the last poster, so you'll have to scroll all the way to the bottom of a very long page to see my pics.
First thing I noticed when I got the car is the huge wheel well gap, especially in the rear. I think this is highlighted by the extra low profile tires that I have. So first thing that came to mind is either a magnetic or air adjustable suspension set up that will not mess with the Dynamic Handling. I'm wondering if anyone has done this set up on their X3. I'm also a fan of aftermarket exhausts and wondering if anyone can make a recommendation on a good set up for the X3 since it is after all an Msport model so having a little louder exhaust tone is probably not a bad thing. I'd be curios what it would sound like before even considering purchasing it though since I've never heard a BMW SUV with one. Thanks in advance. |

Although I am biased with my research into the aerodynamics of our X3, it would be an interesting exercise if BMW could run Richy's X4 with its mods in their wind-tunnel compared with a stock X4. Selfishly, I would be interested to see how the Cd would change at high speed when the frame was lowered for it would translate over to us as well (albeit to a lesser degree given the X4's physical form), especially as the air suspension is on our 'Wish list'.

My general experience from windtunnel tests:
-lowering means less air under vehicle= slightly less drag (Cd) - almost same at all speeds. In the region of 5% of total drag. -tilting forward would probably have same impact - only slightly more so. I can - of course - not feel any difference of the Cd on my - 1 1/2 inch - lowered X4, but more so on: steering precision, steer-into-a-curve, straight ahead stability and sidewindsensitivity- and not-so-positive: ridecomfort. |

I would suggest getting a muffler delete or a catless downpipe or both.
A flash tune would be best and would allow you to run catless downpipe without any indication on the dash. A must would be tint for the windows, some better tires, and blacked out grilles.

Thanks Tjalle! That X4 does look sleek when lowered. I didn't realize that an air suspension system can take up so much room. It pretty much takes all of the space on the spare tire well. I'm not sure if I'm willing to do that especially that the X3's storage is already minimal as it is. It'd be interested to know if he has Dynamic Handling, and if so if it affected it, like throw some kind of error code or cause it to malfunction.

Richi has everything on his vehicle, but they had to take out springs AND shocks when installing the airride.
It should not cause the VDC to malfunction, but probably trigger an error code - which seem to be easy to correct. I only changed springs to lower mine, which is a compromise - I am now slightly riding on bumpstops. The correct way to do this is, of course, to also change to shorter shocks - preferrably with adjustable shocks. One of the German tuning companies might have this - but it will not come cheap. |

I've already did the tint job early this week as I too need to have those in there. I'm not sure how a black out grill would look on a black car, but it does offer an attractive contrast on a white car. I did see a blacked out X3 with a black grill but wasn't that attractive to me and I'm not sure if it was because of the fact that everything was black. Tuning might come later when I feel the need for more than what it got, or perhaps gets assigned to Germany so I can drive it in the Autobahn |

Not sure what the new Remus may sound like, but I have a clip of a Remus exhaust I REALLY like..not sure if it is catless (It's on an E83 not the newer F25) or what since the description is in German--sounds fantastic to me though.

This unfortunately is the old x3 so it is highly unlikely the remus muffler for the f25 will sound like this.

This one sounds like a straight pipe Honda civic. I find deep low tone growl exhaust sound much more attractive than high pitched ones. I've heard of 4 cylinder engines with such sound before, but I'm not sure if the manufacturers make them for X3.
