They are a bit thicker, so probably a little noisier at high speeds than the OEM parts which are very thin and probably why the OEMs weight capacity is much lower. 5 or a 3 for my 10-year old. This is my review on the day one not sure what other downsides this case has. I have lowered the rating to 3 stars because I already have holes in the soles of the slippers. The you tube directions for setting up the camera are helpful. la seul affaire j avais lu dans les commentaire qu il y avait des autocollant. Bike rack works excellent on my 2008 Jeep Wrangler JKU. You can see in a couple of my photos they aren’t a symmetrical bar. When we go to a dock & dine restaurant they all have cleats so I just hook onto those.
