I'm sure it's been covered many times. I just got tired from the clips falling off. A member here on a CL posted he found some clips at AutoZone that worked. Just making a new thread to show the clips vs OEM. They have a better bite overall. I tried pulling them to see if they would slip out. They didn't budge. Time will tell after some highway driving of course.

 

OR...you cam just remove those ugly looking things. LOL! One of the first "mods" I did to my IS350 after my initial purchase.

 

Or you can use zip ties, you can't see them anyway.

 

LOL well it's too late. Like I said I pretty much got tired of hearing people asking. What's those things hanging from your car. I didn't want to remove them. As for now I pushed it to pretty hard. The clips are still holding well. Lexus should of got similar OD to these to begin with.
