Fast and easy

Tried looking for a lower price else where, but couldn't. As soon as another part becomes available on your site, I'll be back! Awesome site, easy browsing, and Paypal!

Spoke to auto tech to see if sold in sets of two, he said yes. Placed order. Very easy. Thanks! After I received order, found out from the tire company, I only needed one box. Returned the other box. Now I found out, it is the wrong part for my car. I will have to see if they take back this one. Must take pictures and email tracking number for returns. Must be shipped within 5 days.

Thank you

I think it comes one set left and right it's not indicating I will see
