bad customer service in my opinion. and you see what the end result was, they lost a sale and possibly lost a customer for life. their company is suppose to be an expert in tires and wheels. you'd figure they'd help any potential customer (and past customers) with their tires and wheels needs, or any items associated with the two.
i'm not surprised though. i use to own an e34, and a lot of the aftermarket wheels have hubs made for the e39, which means you have to use hub centric rings. i got my hub centric rings from tirerack, and didn't run into any issues, probably because i ordered by their part number. but countless other e34 owners have run into problems, where basically tirerack asks if they bought the wheels from tirerack. if the owner's answer is no, tirerack would refuse the sale. they seem to have some type of weird policy.
