Customers' comments

These are the perfect addition to my JCW. I have a red over black JCW with the Xenon head lamps & black housings. These are the perfect way to tone down the brash bright red of the tail/brake lamp housings to match the front lamps. Not only do you eliminate the chrome but the housing itself is black thus darkening the appearance of the entire assembly. I would say these should be flying off the shelf but i don't want everyone to have a MINI that looks as good as mine.

Swing, batter, batter, batter, SWING!
I always hit a home run with parts and great customer service from OUTMOTORING. Aaron and the gang are always helpful and they've got the goods I'm looking for. THANKS!!!

The owner is nice, prices are in line with others or better. My complaints are twofold. First not a blasted thing comes with any installation instructions. The Eventuri intake had excellent ones you could download, the rest had nothing. I guess you are supposed to know how to install before you buy.
Second, I have left a lot of reviews on products (most of them very favorable) and yet they don't show up under the product listing. I rely heavily on customer reviews as I have found they are generally the best gauge of the product. It has aggravated me beyond speaking that I spend the time writing a detailed review, only to never have it post. When I go to the item, it will say "no reviews for this product" and then underneath it "you have written a review for this product". Seriously?
