Well, I've order once for SLR - a set of Bilstein shocks. Was told I would get an email with the tracking number, did not. Called back numerous times to find out if they had shipped, after about the third time when someone finally had the time to look for my order while I was on the phone (the other times I was promised a call back which I never got), I was told they had not shipped yet, and that when they they would call me with the tracking number. Finally after a couple of weeks of this I sent an email to the owner, and a couple a days later I got an email back with the tracking number. Which also happened to be day the shocks showed up at my door. Sorry, this type of customer service sucks, and it was my first and last time to order anything from them.
