Thule or OEM Cross Bars

The price is about the same. Has anyone compared the OEM BMW Accessory and the Thule AeroBlade bars? Before I spend the ~$300, can anyone suggest pro's and con's?

I agree the BMW bars are very noisy.

I now have the Thule and it's much better, not to mention there are so many more choices for things I can mount!

Interesting, as I have BMW bars and during the last two ski trips my passengers were commenting how quiet the car is @ 90mph even with a pair of skis on the roof. Initially I was concerned with the possible noise and was going to take the bars off once the season was over, but ended up keping them on since I couldn't spot any increase in ambient noise.

I have the OE bars, I use them with a Thule 2100 roof box and my bike racks. Traffic here moves at around 120-130 km/hr on the 401, and once you go over 120km/hr, you can definitely notice the additional noise

Hang on guys; apples to apples. I know there will be extra noise with a roof box or a bike rack. But what about with the naked bars - when you are not tansporting anything?

Even with just the naked bars, you can hear the difference.

Currently I use Whispbar System in my car (vw passat) - I can recommend it as really quiet -> check here: http://www.yakima.com/shop/baserack/whispbar-s46-rail

I plan to purchase the same one for the X5 I'm waiting for (delivery date in about 3 weeks).

I have tried both - Thule (oval shaped) and OEMs. I have to say that OEMs produced significantly less noise (when properly installed!) than Thule. Thule were noisy around the ends, as they were sticking out and creating wind turbulence. OEMs dont have sticking-out ends.

With Thule's, you need to get their special air deflector to minimize noise, then again most of the noise is coming from the ends. In the end I am keeping OEMs.

The only pro of Thule is that they are sitting approx 0.75" lower than OEMs, making it easier to load up - either bike rack or box.

I am wondering if there would be issues with the sunroof since these sit so low?

For noisy OEM bar installation, do you have the correct bar up front with the little air spoilers installed? The OEM bars are on all the time with acceptable wind noise IMO.

Yes, it has 3 little plastic things attached to the front bar.

Pricey !!!! But designed to be never taken off...

I suspect very low install might cause problems when you installing the box, as depending on mounting bracket they might be touching the glass. Also, very small clearance might end up causing whistlening effect.

You mean the little plastic thing that does't really do anything? Yes I have that attached and it sounds like it's not doing anything.

I'm assuming no pun intended "sounds like it's not doing anything". They are suppose to force airflow separation on bottom of the bar too reduce Karman vortexes from building behind the bar to reduce sound vibration. How well they work is debatable but here are some things to try, make sure top rubber strips installed and reposition the bars forward/aft to reduce interactions. I looked at the yak and thrule racks but didn't like the look. To each his own I guess.

Am curious about this too. I was thinking of the Thule as I can use the same setup on my other car too.

Whats the verdict on the OEM bars with noise when you have the big sun roof. Some are saying quite others say really noisy. Which one?? The
whisper bars might work, but it looks like they sit really low and dont give much clearance under them, especially with the sunroof.

I have the Thule quiet bars, forgot the marketing name. They work great, very quiet (in spite of the big sunroof). With the Ski holder, they get noisier, but you have a 6" vertical barrier sticking up.

I say sunroof closed, shade closed undetectable up to 80 MPH (did not try above). Shade open but sunroof closed... slight noise at 60+. But very tolerable.

BTW, with the bindings down you can not flip the sunroof up unless you pay attention to the exact location of bindings. Of course with bindings up and flat skis on the rack there is plenty of room for the sunroff to flip up.

Now, any accessory installed on the cross bar is likely to be a bit noisy. Cross bars come off so easilly, that I just removed them along with the ski holder accessory.

I bought the BMW cross bars and have not noticed any unusual noise. I am very happy.
