I have a 2015 RT-S SM6. I know there are at least 3 different makers of floor boards for the manual transmission. Rivco, CanAmSpyderAccessories, and Inspector Gadget. Has anyone used these and their thoughts? Or any others I am missing? I know on the Inspector Gadget you have to use their heel-toe shifter. Thinking these and new seat will be cheaper than new Spyder.
