I fitted these some genuine Nissan splash guards some time ago. It took me a long time to decide to get them as I wasn't 100% sure I liked the look. One thing that swayed me was the fact I've got spacers they might help keep the car cleaner now the wheels stick out further. Anyway, here are some pics after I fitted them: Having driven through a lot of bad weather since I can say the front splash guards really help reduce the amount of spray up the sills. I am not sure the rears really do much but they might reduce the spray if you are following, I couldn't say. Other than rain and a little snow I'd not given them a decent test until I had to make a flying visit to Cornwall when I found some extremely dirty roads. This was the result: I think it's fair to say it saved a lot of 'mud' being sprayed up the side of the car!
