I have mud guards on my car and i found them to be kind of useless. The 3IS is probably the worst car I've ever owned for flinging stuff onto the sides of the cars. I have mudguards and extended side skirts, made no difference.

This seller is passing these off as authentic. I am unsure if they are.

 

I just got mine and they look exactly like that, but haven't put them on yet. Were only half the price though, and didn't come from Hong Kong.

 

Called the dealer, and Parts said there aren't OEM Lexus mudflaps for 3IS.

Also asked them about "plugs", as the front fenders seem to have plugs that line up with the holes on the flaps but the rears do not. Would appear we need to drill holes for the back? Kindof wonder about rust with putting bare screws in there.

 

I ordered mine from the UK. You won't find them in North America i believe.

 

 

sorry i cant remember... i do remember it being hard to find. I ended up installing some ebay ones to fit my side skirts (they were a bit thinner), if i were you i would go with that same quality and significantly cheaper.

 

sorry a bit off topic but I sent you a message regarding the f-sport exhaust you had for sale.
