need more info on page for parts like what engine is in your car other then that everything was great

product just as described, received in 3 days

I paid for 2nd day shipping and 5 days later they were shipped out. So, I should receive my rotors in a full week from when I paid for 2 day shipping. I called customer service and they discounted the shipping rate to ground service. At least they were polite and helpful in the phone.

Best price for the particular part I was ordering. Their staff/customer service is very helpful and polite, but unfortunately their shipping times are lacking. Before ordering on Monday, I called to verify the item was in stock, and asked what shipping method I would need to ensure it would arrive before Saturday. I was told 2nd Day Air. I ordered that same day (around 1pm). The package wasn't shipped until Wednesday evening, AFTER I called and inquired a to why it hasn't moved. What really upset me though was that the package ended up being shipped UPS Ground anyways, to arrive here the very next day. Long story short, I shouldn't have had to pay the extra $20+.

Great prices will shop here again.

Excellent on-line merchant with outstanding customer service and the best prices on equipment and shipping. Highly reccomended!

Good prices and easy ordering process (order #18003). The only issue that I had was after placing the order, completing the entire process, I received three emails stating that "We noticed that you started checking out on our site, but didn't quite finish the process". After calling customer service, they ensured me that the order was complete. Since then, I receive the same email(3 emails at a time) on a daily basis. Just a little annoying, but easy enough to delete.
