Good price

great so far

good

Great easy process to order

The item could have more pictures from different sides and dimensions.

Great price - even with shipping price was still 10% less than the lowest price I found with "free" shipping. Great communication and fast shipping. Glad I found the site!

Don't see where my coupon code took off 10%. Also did not receive a second email with tracking info. First e-mail said we would receive a tracking number in next email.

very good price on ebc rotors. the shipping was about avg $ and was sent fedex, amazing it got here without being damaged, but was delivered quickly. would buy from again if prices stay low

Thank You

I just received my order, I was expecting it on Saturday so that was a nice surprise. I will have to install it in my car and then finish my comments. Then I will let you know the rest of the story. Thank you.
