I just ordered a set of 4 mud guards for my LS460L. If anyone else is interested here's the link:

Now I need to find installation instructions in English.

 

the same mud flaps for the 2013 are $600.00, from the same site.

 

Mine is a 2010 and with shipping it will be $440. A little steep but I'm so tired of washing then it looking like I went off roading a mile down the street.

 

Someone from Japan is selling the same stuffs on eBay for $424 shipped.
Look like it is pretty easy to install.

 

Agreed they seem to be pretty simple to install.

 

These are "stupid easy" to install. I got mine on in less than 30 minutes.

 

Can anyone tell me if the factory mud flaps for a LS 460 are flexible? My wife's car had with mud flaps that were made from fiberglass (or some hard material). They would hit on the speed bumps in malls and other places. They finally broke off and I replaced them with flexible ones (rubber, plastic or something),
I would like to get Lexus mud flaps for my car but not if they are going to break!
