I had a bad experience with Toytec. The 550 coils were warping in towards the shock body til it looked like they might rub, so Doug sent replacement springs, which I changed out. Same thing happened again, so he ask me to send them in. He said nothing was wrong with them, and sent them back, only they never showed up.
Doug told me it was "suspicious" that they were missing. He was inferring that I took them and was commiting fraud. In the end, he said I could take a used set or a partial refund.
I was fed up by this time and just wanted my money back, but he insisted on shorting me $125., even though he shipped them insured UPS. I'll never deal with him again
