my rx8 lasted about 7 weeks. It was the 4 hole. I live up in Canada but am about 3hrs away from the Idaho border. I arranged to have it shipped back to an Idaho shipping address so I could just pick it up and save the 2 week delay through customs. I was told 4 times it would be no problem. I took the day off work cancelled my other weekend plans and made the trip because we don't have much season left and I don't have a spare. Now I am here with my truck, all spare parts, laptop and find out that they shipped it to the Canadian address instead of the Idaho address. 2 thumbs down for a product that does not last 2 months, 2 thumbs down for customer service in regards to the shipping.
