I've posted this before but I was considering getting the mud flaps, front and rear, for my new XC90. I found them online for $130 shipped in the U.S. with no tax except in Rhode Island
on Steingold Volvo's parts webpage. The front mudflaps
can be found here, (those are for people without a body kit) and the rear mudflaps
can be found here. I received the mudflaps aprox. a week after ordering and they printed out all the installation instructions and included them in the box as well. I had already viewed the installation instructions online and knew they would be a breeze to install but having them print and send them in the box is a good thing for those who do not research installation beforehand.
The install took me aprox. 35 minutes and that was only because I had some Opticoat 2.0 left over and took the extra time to alcohol prep and then opticoat each one before installing. Installation was as easy as removing 3 10mm screws from each wheel well and then installing the flap using 3 new 10mm screws for each flap in each wheel well.
I don't think on my Onyx Black First Edition they look 'bad'. I was getting minor mud and road grime splatter on the doors which is what made me consider them. I can say after 1 1/2 weeks of having them including a road trip last weekend, they do help minimize 'splatter' on the doors even up to the side view mirrors.
Here's pics of them installed for anyone who may be on the fence and was hoping to see pics of them installed.
