Parts were actually in-stock unlike every other retailer I tried. Quick shipping too.

Recent purchased new Hawk HPS brakes for my 2010 Hyundai Genesis Coupe 3.8 Track.

The order was processed quickly, packaged very well, and was the correct items I had ordered.

Not only did I experiece great customer service and quick shipping/processing, Autoplicity also had the LOWEST price of any vendors for these parts I could find online.

Great service + Great pricing = Match made in heaven!

Had problems using the search tool so I called direct. They helped locate Air Lift shocks I needed and told me that I.E. browser is sometimes a problem. They were helpful and my items got shipped the next business day.
