so far so good!!!

very good

Quick, easy and the best price

Lowest price anywhere on EBC brakes, got front and rear sets for 2011 Camaro SS for the price of just the fronts anywhere else, and that is with shipping included! Now I know why the other guy had "free shipping" just added it plus some to the cost of the parts! Now don't get me started on UPS though, but that isn't the vendors fault fedex is just as bad and DHL died.

I have used them a couple times. Always seem to be one of the lowest prices on the internet and pretty quick turnaround on shipping. If you live near Los Angeles, they have a warehouse in Cerritos, so things arrive real quick once they're shipped.

This was my second order with Autoplicity. The first order I had to call to get an update, but just happens the part was out for delivery the day I had called. This second order went without a hitch! In both cases, shipping was fast and the products delivered at great prices, not to mention some of the best prices on shipping. I will definitely look here for my future parts needs!!
