Installed this set on my 2017 Infiniti Q60 Red Sport. I had previously installed the SPL Parts Rear Camber and Toe Arms, in conjunction with RS-R Best*I Active C/Os. Biggest difference over the OEM traction arms is this upgrade keeps the tires planted to ground in higher-speed turns and during left/right turn on/off throttle transitions, as the weight shifts and rear tires are loaded/unloaded. Overall, the rear suspension and ride quality has firmed up, as expected.
