OK I test rode my Spyder with the new 185 S Drives and it seems to be really lite or too easy to move (at highway speeds). I don't feel any steering resistance. It tracks really well almost too good. I wasn't expecting that. Maybe after a Laser alignment it will be different. Im just reporting my findings. I haven't tested them on any twisty roads yet. Ill probably do that at Spyderfest 2018...
