Update by user Jul 17, 2018 Resolved Original review posted by user Jul 16, 2018 Returned defective items to summit, received credit. Months later placed a new order, was told that my account was on hold because I had received a double credit. I asked for documentation, was sent copy of orig. order & orig. credit. Nowhere did it show a extra credit, nor did my credit card summary show this supposed "extra" credit. These folks are at worst dishonest, at best just stupid, u chose. Better off going with Speedway or Jeg. No one signed the letter I was sent demanding money I do not owe, so I have no way to even follow up. This used to be a top notch supplier, however over the last 5 years more & more of their product is being imported from China, it is ill fitting & of very poor quality.
