I am buying the Whiteline sways. I had them and liked them on my RX8. A side note, the performance End links I bought required drilling out to fit. I burnt up two cobalt drill bits drilling through the sways, gave up and took them to a machine shop. They also had trouble drilling the hole to a slightly larger size. The Tech said that was some of the toughest spring steel he had seen. I recommend buying their end links that are made to fit.
